Strength training has a range of benefits for women. Here are 4 ways to get into weights

<p><em><a href="https://theconversation.com/profiles/erin-kelly-1497598">Erin Kelly</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p>Picture a gym ten years ago: the weights room was largely a male-dominated space, with women mostly doing cardio exercise. Fast-forward to today and you’re likely to see women of all ages and backgrounds confidently navigating weights equipment.</p> <p>This is more than just anecdotal. According to data from the <a href="https://app.powerbi.com/view?r=eyJrIjoiZGU1YWFhZDgtMmRhZi00YTgyLThhMzItYjc2ODk5NTg0MTg1IiwidCI6IjhkMmUwZjRjLTU1ZjItNGNiMS04ZWU3LWRhNWRkM2ZmMzYwMCJ9">Australian Sports Commission</a>, the number of women <a href="https://www.clearinghouseforsport.gov.au/research/ausplay/results#portal">participating in weightlifting</a> (either competitively or not) grew nearly five-fold between 2016 and 2022.</p> <p>Women are discovering what research has long shown: strength training offers benefits beyond sculpted muscles.</p> <h2>Health benefits</h2> <p><a href="https://www.womenshealth.gov/a-z-topics/osteoporosis">Osteoporosis</a>, a disease in which the bones become weak and brittle, affects more women than men. Strength training increases <a href="https://www.mayoclinic.org/healthy-lifestyle/fitness/in-depth/strength-training/art-20046670">bone density</a>, a crucial factor for <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-8-47">preventing osteoporosis</a>, especially for women negotiating menopause.</p> <p>Strength training also improves <a href="http://link.springer.com/10.1007/s40279-015-0379-7">insulin sensitivity</a>, which means your body gets better at using insulin to manage blood sugar levels, reducing the risk of type 2 diabetes. Regular strength training contributes to better <a href="https://doi.org/10.1139/apnm-2020-0245">heart health</a> too.</p> <p>There’s a mental health boost as well. Strength training has been linked to reduced symptoms of <a href="https://doi.org/10.1001/jamapsychiatry.2018.0572">depression</a> and <a href="http://link.springer.com/10.1007/s40279-017-0769-0">anxiety</a>.</p> <h2>Improved confidence and body image</h2> <p>Unlike some forms of exercise where progress can feel elusive, strength training offers clear and tangible measures of success. Each time you add more weight to a bar, you are reminded of your ability to meet your goals and <a href="https://www.tandfonline.com/doi/full/10.1080/2159676X.2019.1634127">conquer challenges</a>.</p> <p>This sense of achievement doesn’t just stay in the gym – it can change how women see themselves. A <a href="https://linkinghub.elsevier.com/retrieve/pii/S1755296623000194">recent study</a> found women who regularly lift weights often feel more empowered to make positive changes in their lives and feel ready to face life’s challenges outside the gym.</p> <p>Strength training also has the potential to positively impact <a href="https://journals.lww.com/nsca-jscr/abstract/2002/11000/Relations_of_Strength_Training_to_Body_Image_Among.25.aspx">body image</a>. In a world where women are often judged on appearance, lifting weights can shift the focus <a href="http://journals.sagepub.com/doi/10.1177/0193732502238256">to function</a>.</p> <p>Instead of worrying about the number on the scale or fitting into a certain dress size, women often come to appreciate their bodies for what they can do. “Am I lifting more than I could last month?” and “can I carry all my groceries in a single trip?” may become new measures of physical success.</p> <p>Lifting weights can also be about challenging outdated ideas of how women “should” be. Qualitative <a href="https://journals.humankinetics.com/view/journals/wspaj/aop/article-10.1123-wspaj.2022-0088/article-10.1123-wspaj.2022-0088.xml">research</a> I conducted with colleagues found that, for many women, strength training becomes a powerful form of rebellion against unrealistic beauty standards. As one participant told us:</p> <blockquote> <p>I wanted something that would allow me to train that just didn’t have anything to do with how I looked.</p> </blockquote> <p>Society has long told women to be small, quiet and not take up space. But when a woman steps up to a barbell, she’s pushing back against these outdated rules. One woman in our study said:</p> <blockquote> <p>We don’t have to […] look a certain way, or […] be scared that we can lift heavier weights than some men. Why should we?</p> </blockquote> <p>This shift in mindset helps women see themselves differently. Instead of worrying about being objects for others to look at, they begin to see their bodies as capable and strong. Another participant explained:</p> <blockquote> <p>Powerlifting changed my life. It made me see myself, or my body. My body wasn’t my value, it was the vehicle that I was in to execute whatever it was that I was executing in life.</p> </blockquote> <p>This newfound confidence often spills over into other areas of life. As one woman said:</p> <blockquote> <p>I love being a strong woman. It’s like going against the grain, and it empowers me. When I’m physically strong, everything in the world seems lighter.</p> </blockquote> <h2>Feeling inspired? Here’s how to get started</h2> <p><strong>1. Take things slow</strong></p> <p>Begin with bodyweight exercises like squats, lunges and push-ups to build a foundation of strength. Once you’re comfortable, add external weights, but keep them light at first. Focus on mastering <a href="https://theconversation.com/what-are-compound-exercises-and-why-are-they-good-for-you-228385">compound movements</a>, such as deadlifts, squats and overhead presses. These exercises engage multiple joints and muscle groups simultaneously, making your workouts more efficient.</p> <p><strong>2. Prioritise proper form</strong></p> <p>Always prioritise proper form over lifting heavier weights. Poor technique can lead to injuries, so learning the correct way to perform each exercise is crucial. To help with this, consider working with an exercise professional who can provide personalised guidance and ensure you’re performing exercises correctly, at least initially.</p> <p><strong>3. Consistency is key</strong></p> <p>Like any fitness regimen, consistency is key. Two to three sessions a week are plenty for most women to see benefits. And don’t be afraid to occupy space in the weights room – remember you belong there just as much as anyone else.</p> <p><strong>4. Find a community</strong></p> <p>Finally, join a community. There’s nothing like being surrounded by a group of strong women to inspire and motivate you. Engaging with a supportive community can make your strength-training journey more enjoyable and rewarding, whether it’s an in-person class or an online forum.</p> <h2>Are there any downsides?</h2> <p>Gym memberships can be expensive, especially for specialist weightlifting gyms. Home equipment is an option, but quality barbells and weightlifting equipment can come with a hefty price tag.</p> <p>Also, for women juggling work and family responsibilities, finding time to get to the gym two to three times per week can be challenging.</p> <p>If you’re concerned about getting too “bulky”, it’s very difficult for <a href="https://journals.sagepub.com/doi/epub/10.1177/0031512520967610">women</a> to bulk up like male bodybuilders without pharmaceutical assistance.</p> <p>The main risks come from poor technique or trying to lift too much too soon – issues that can be easily avoided with some guidance.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221307/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/erin-kelly-1497598"><em>Erin Kelly</em></a><em>, Lecturer and PhD Candidate, Discipline of Sport and Exercise Science, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Want the health benefits of strength training but not keen on the gym? Try ‘exercise snacking’

<p><em><a href="https://theconversation.com/profiles/justin-keogh-129041">Justin Keogh</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/jackson-fyfe-134774">Jackson Fyfe</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>The science is clear: <a href="https://cdnsciencepub.com/doi/full/10.1139/apnm-2020-0245">resistance training</a> is crucial to ageing well. Lifting weights (or doing bodyweight exercises like lunges, squats or push-ups) can help you live independently for longer, make your bones stronger, reduce your risk of diseases such as diabetes, and may even improve your <a href="https://pubmed.ncbi.nlm.nih.gov/28919335/">sleep and mental health</a>.</p> <p>But not everyone loves the gym. Perhaps you feel you’re not a “gym person” and never will be, or you’re too old to start. Being a gym-goer can be expensive and time-consuming, and some people report feeling <a href="https://www.reddit.com/r/StartingStrength/comments/j3hq32/unwelcome_feeling_at_the_gym/">unwelcome</a> or <a href="https://www.quora.com/I-feel-awkward-and-I-want-to-start-a-gym-but-could-not-What-should-I-do">awkward</a> at the gym.</p> <p>The good news is you don’t need the gym, or lots of free time, to get the health benefits resistance training can offer.</p> <p>You can try “exercise snacking” instead.</p> <h2>What is exercise snacking?</h2> <p>Exercise snacking involves doing multiple shorter bouts (as little as 20 seconds) of exercise throughout the day – often with minimal or no equipment. It’s OK to have <a href="https://doi.org/10.1007/s40279-021-01605-8">several hours of rest</a> between.</p> <p>You could do simple bodyweight exercises such as:</p> <ul> <li> <p>chair sit-to-stand (squats)</p> </li> <li> <p>lunges</p> </li> <li> <p>box step-ups</p> </li> <li> <p>calf raises</p> </li> <li> <p>push-ups.</p> </li> </ul> <p>Exercise snacking like this can help improve muscle mass, strength and physical function.</p> <p>It’s OK to hold onto a nearby object for balance, if you need. And doing these exercises regularly will also improve your balance. That, in turn, reduces your risk of falls and fractures.</p> <h2>OK I have done all those, now what?</h2> <p>Great! You can also try using resistance bands or dumbbells to do the previously mentioned five exercises as well as some of the following exercises:</p> <ul> <li> <p><a href="https://youtu.be/IP4wM2JpDdQ?si=1B1GyV_FY5rcArW8&amp;t=6">seated rows</a></p> </li> <li> <p><a href="https://youtu.be/G6GIffCaJCQ?si=RxXZtzMqQ0DGxF3k&amp;t=48">chest</a> and <a href="https://www.youtube.com/watch?v=TUnnz5i4Mnw&amp;t=5s">shoulder presses</a></p> </li> <li> <p><a href="https://youtu.be/z0omicIkYu4?si=8WffT3ij12SNTqEs">bicep curls</a></p> </li> <li> <p><a href="https://www.youtube.com/watch?v=5wXVnxBgLHo">knee extensions</a></p> </li> <li> <p><a href="https://www.youtube.com/watch?v=LtTcXXgeRYo">leg curls</a>.</p> </li> </ul> <p>When using resistance bands, make sure you hold them tightly and that they’re securely attached to an immovable object.</p> <p>Exercise snacking works well when you pair it with an activity you do often throughout the day. Perhaps you could:</p> <ul> <li> <p>do a few extra squats every time you get up from a bed or chair</p> </li> <li> <p>do some lunges during a TV ad break</p> </li> <li> <p>chuck in a few half squats while you’re waiting for your kettle to boil</p> </li> <li> <p>do a couple of elevated push-ups (where you support your body with your hands on a chair or a bench while doing the push-up) before tucking into lunch</p> </li> <li> <p>sneak in a couple of calf raises while you’re brushing your teeth.</p> </li> </ul> <h2>What does the evidence say about exercise snacking?</h2> <p>One <a href="https://pubmed.ncbi.nlm.nih.gov/31687210/">study</a> had older adults without a history of resistance training do exercise snacks at home twice per day for four weeks.</p> <p>Each session involved five simple bodyweight exercises (chair sit-to-stand, seated knee extension, standing knee bends, marching on the spot, and standing calf raises). The participants did each exercise continuously for one minute, with a one-minute break between exercises.</p> <p>These short and simple exercise sessions, which lasted just nine minutes, were enough to improve a person’s ability to stand up from a chair by 31% after four weeks (compared to a control group who didn’t exercise). Leg power and thigh muscle size improved, too.</p> <p>Research involving one of us (Jackson Fyfe) has also <a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-022-03207-z">shown</a> older adults found “exercise snacking” feasible and enjoyable when done at home either once, twice, or three times per day for four weeks.</p> <p>Exercise snacking may be a more sustainable approach to improve muscle health in those who don’t want to – or can’t – lift heavier weights in a gym.</p> <h2>A little can yield a lot</h2> <p>We know from other research that the more you exercise, the more likely it is you will <a href="https://www.sciencedirect.com/science/article/pii/S0167268119302586">keep exercising in future</a>.</p> <p>Very brief resistance training, albeit with heavier weights, may be more <a href="https://pubmed.ncbi.nlm.nih.gov/29975122/">enjoyable</a> than traditional approaches where people aim to do many, many sets.</p> <p>We also know brief-and-frequent exercise sessions can break up <a href="https://pubmed.ncbi.nlm.nih.gov/26378942/">periods</a> of sedentary behaviour (which usually means sitting too much). Too much sitting increases your risk of chronic diseases such as diabetes, whereas exercise snacking can help keep your <a href="https://pubmed.ncbi.nlm.nih.gov/36921112/">blood sugar levels steady</a>.</p> <p>Of course, longer-term studies are needed. But the evidence we do have suggests exercise snacking really helps.</p> <h2>Why does any of this matter?</h2> <p>As you age, you lose strength and mass in the muscles you use to walk, or stand up. Everyday tasks can become a struggle.</p> <p>All this <a href="https://pubmed.ncbi.nlm.nih.gov/36907247/">contributes</a> to disability, hospitalisation, chronic disease, and reliance on community and residential aged care support.</p> <p>By preserving your muscle mass and strength, you can:</p> <ul> <li> <p>reduce joint pain</p> </li> <li> <p>get on with activities you enjoy</p> </li> <li> <p>live independently in your own home</p> </li> <li> <p>delay or even eliminate the need for expensive health care or residential aged care.</p> </li> </ul> <h2>What if I walk a lot – is that enough?</h2> <p>Walking may maintain some level of lower body muscle mass, but it won’t preserve your <a href="https://pubmed.ncbi.nlm.nih.gov/38190393/">upper body muscles</a>.</p> <p>If you find it difficult to get out of a chair, or can only walk short distances without getting out of breath, resistance training is the best way to regain some of the independence and function you’ve lost.</p> <p>It’s even more important for women, as muscle mass and strength are typically lower in older women than men. And if you’ve been diagnosed with osteoporosis, which is more common in older women than men, resistance exercise snacking at home can improve your balance, strength, and bone mineral density. All of this reduces the risk of falls and fractures.</p> <p>You don’t need <a href="https://pubmed.ncbi.nlm.nih.gov/37171517/">heavy weights</a> or fancy equipment to benefit from resistance training.</p> <p>So, will you start exercise snacking today?<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/232374/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/justin-keogh-129041">Justin Keogh</a>, Associate Dean of Research, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/jackson-fyfe-134774">Jackson Fyfe</a>, Senior Lecturer, Strength and Conditioning Sciences, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Resistance (exercise) is far from futile: The unheralded benefits of weight training

<p><em><a href="https://theconversation.com/profiles/stuart-phillips-428766">Stuart Phillips</a>, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a> </em></p> <p>Everyone can agree that exercise is healthy. Among its many benefits, exercise improves heart and brain function, aids in controlling weight, slows the effects of aging and helps lower the risks of several chronic <a href="https://doi.org/10.1101%2Fcshperspect.a029694">diseases</a>.</p> <p>For too long, though, one way of keeping fit, aerobic exercise, has been perceived as superior to the other, resistance training, for promoting health when, in fact, they are equally valuable, and both can get us to the same goal of overall physical fitness.</p> <p>Aerobic exercise such as running, swimming and cycling is popular because it provides great benefits and with ample <a href="https://doi.org/10.1371/journal.pmed.1001335">scientific evidence</a> to back that up.</p> <p>What has been far less influential to date is that resistance training — whether that’s with dumbbells, weightlifting machines or good old push-ups, lunges and dips — works about as well as aerobic exercise in all the critical areas, including cardiovascular health.</p> <p>Resistance training provides another benefit: building strength and developing power, which become increasingly important as a <a href="https://doi.org/10.1007/s12603-021-1665-8">person ages</a>.</p> <figure><iframe src="https://player.vimeo.com/video/843867756" width="500" height="281" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Video about different forms of resistance training explores how all are effective at building strength.</span></figcaption></figure> <p>Building and maintaining muscle strength keeps us springing out of our chairs, maintaining our balance and posture and firing our metabolism, as my colleagues and I explain in a paper recently <a href="https://doi.org/10.1249/FIT.0000000000000916">published</a> by the American College of Sports Medicine.</p> <p>So, if aerobic exercise and resistance training offer roughly equal benefits, how did we end up with so many runners and cyclists compared to weightlifters?</p> <p>It was a combination of timing, marketing and stereotyping.</p> <h2>The rise of aerobics</h2> <p>The preference for aerobic exercise dates back to landmark research from the <a href="https://www.cooperinstitute.org/research/ccls">Cooper Centre Longitudinal Study</a>, which played a pivotal role in establishing the effectiveness of aerobics — Dr. Ken Cooper invented or at least popularized the word with his book <a href="https://www.cooperaerobics.com/About/Aerobics.aspx"><em>Aerobics</em></a>, spurring desk-bound Baby Boomers to take up exercise for its own sake.</p> <p>Meanwhile, resistance training languished, <a href="https://www.cnet.com/health/fitness/does-lifting-weights-make-women-bulky/">especially among women</a>, due to the misguided notion that weightlifting was only for men who aspired to be hyper-muscular. <a href="https://www.britannica.com/biography/Charles-Atlas">Charles Atlas</a>, anyone?</p> <p>Cultural influences solidified the dominance of aerobic exercise in the fitness landscape. In 1977, Jim Fixx made running and jogging popular with <a href="https://en.wikipedia.org/wiki/The_Complete_Book_of_Running"><em>The Complete Book of Running</em></a>. In the 1980s, Jane Fonda’s <a href="https://www.janefonda.com/shop/fitness-videos/jane-fondas-complete-workout/"><em>Complete Workout</em></a> and exercise shows such as <em><a href="https://www.imdb.com/title/tt0268895/">Aerobicize</a></em> and the <em><a href="https://www.imdb.com/title/tt0299431/">20 Minute Workout</a></em> helped solidify the idea that exercise was about raising one’s heart rate.</p> <p>The very word “aerobic,” previously confined to the lexicon of science and medicine, entered popular culture about the same time as leg warmers, tracksuits and sweatbands. It made sense to many that breathing hard and sweating from prolonged, vigorous movement was the best way to benefit from exercising.</p> <p>All the while, resistance training was waiting for its turn in the spotlight.</p> <h2>Recognizing the value of resistance</h2> <p>If aerobics has been the hare, resistance training has been the tortoise. Weight training is now coming up alongside and preparing to overtake its speedy rival, as athletes and everyday people alike recognize the value that was always there.</p> <p>Even in high-level sports training, weightlifting did not become common until the last 20 years. Today, it strengthens the bodies and lengthens the careers of soccer stars, tennis players, golfers <a href="https://doi.org/10.1007/s40279-016-0486-0">and many more</a>.</p> <p>Rising popular interest in resistance training owes a debt to <a href="https://www.livestrong.com/article/545200-the-fall-of-fitness/">CrossFit</a>, which, despite its controversies, has helped break down stereotypes and introduced more people, particularly women, to the practice of lifting weights.</p> <p>It’s important to recognize that resistance training does not invariably lead to bulking up, nor does it demand lifting heavy weights. As our team’s research has shown, lifting lighter weights to the point of failure in multiple sets provides <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.00154.2016">equal benefits</a>.</p> <h2>Strength and ageing</h2> <p>The merits of resistance training extend beyond improving muscle strength. It addresses a critical aspect often overlooked in traditional aerobic training: the ability to exert force quickly, or what’s called power. As people age, activities of daily living such as standing up, sitting down and climbing stairs demand <a href="https://doi.org/10.1186/s11556-022-00297-x">strength and power</a> more than cardiovascular endurance.</p> <p>In this way, resistance training can be vital to maintaining overall functionality and independence.</p> <h2>Redefining the fitness narrative</h2> <p>The main idea is not to pit resistance training against aerobic exercise but to recognize that they complement each other. Engaging in both forms of exercise is better than relying on one alone. The <a href="https://doi.org/10.1161/CIR.0000000000001189">American Heart Association</a> recently stated that “…resistance training is a safe and effective approach for improving cardiovascular health in adults with and without cardiovascular disease.”</p> <p>Adopting a nuanced perspective is essential, especially when we guide <a href="https://doi.org/10.1016/j.arr.2021.101368">older individuals</a> who may associate exercise primarily with walking and not realize the limitations imposed by neglecting strength and power training.</p> <p>Resistance training is not a one-size-fits-all endeavour. It encompasses a <a href="https://doi.org/10.1016/j.jshs.2023.06.005">spectrum of activities</a> tailored to individual capabilities.</p> <p>It’s time to redefine the narrative around fitness to make more room for resistance training. It’s not necessary to treat it as a replacement for aerobic exercise but to see it as a vital component of a holistic approach to <a href="https://doi.org/10.1249/ESM.0000000000000001">health and longevity</a>.</p> <p>By shedding stereotypes, demystifying the process and promoting inclusivity, resistance training can become more accessible and appealing to a broader audience, ultimately leading to a new way to perceive and prioritize the benefits of this form of training for <a href="https://doi.org/10.1136/bjsports-2021-105061">health and fitness</a>.<!-- Below is The Conversation's page counter tag.

Steep physical decline with age is not inevitable – here’s how strength training can change the trajectory

<p><em><a href="https://theconversation.com/profiles/zachary-gillen-1251178">Zachary Gillen</a>, <a href="https://theconversation.com/institutions/mississippi-state-university-1970">Mississippi State University</a></em></p> <p>Raise your hand if you regularly find yourself walking up a flight of stairs. What about carrying heavy bags of groceries? How about picking up your child or grandchild? Most of us would raise our hands to doing at least one of those weekly, or even daily.</p> <p>As people age, it can become more and more difficult to perform some physical tasks, even those that are normal activities of daily living. However, prioritizing physical fitness and health as you get older can help you go through your normal day-to-day routine without feeling physically exhausted at the end of the day.</p> <p>It can also help you continue to have special memories with your family and loved ones that you might not have been able to have if you weren’t physically active. For example, I ran two half-marathons with my dad when he was in his 60s!</p> <p>I am an exercise physiologist who studies how people can <a href="https://scholar.google.com/citations?user=gn8ZiLMAAAAJ&amp;hl=en">use resistance training to improve human performance</a>, whether it be in sports and other recreational settings, in everyday life, or both. I am also a certified strength and conditioning specialist. My career has given me the opportunity to design exercise programs for kids, college athletes and elderly adults.</p> <p>Staying physically active as you get older doesn’t need to include running a half-marathon or trying to be a bodybuilder; it could be as simple as trying to get through the day without feeling winded after you go up a flight of stairs. Although our muscles naturally get weaker as we age, there are ways we can combat that to help improve quality of life as we get older.</p> <h2>Muscle loss and chronic disease</h2> <p>One of the most important parts of exercise programming, no matter who I am working with, is proper resistance training to build muscle strength. Some amount of age-related loss of muscle function is normal and inevitable. But by incorporating resistance training that is appropriate and safe at any ability level, you can slow down the rate of decline and even prevent some loss of muscle function.</p> <p>The medical term for a condition that involves <a href="https://doi.org/10.1093/ageing/afy169">age-related loss of muscle function and mass is sarcopenia</a>. Sarcopenia can begin as early as age 40, but it tends to be <a href="https://doi.org/10.1097/01.mco.0000134362.76653.b2">more common in adults age 60 and older</a>. Sarcopenia is associated with a number of health issues such as <a href="https://doi.org/10.1093/gerona/glx245">increased risk of falling</a>, <a href="https://doi.org/10.1161/CIRCULATIONAHA.123.064071">cardiovascular disease</a> and <a href="https://doi.org/10.3390/nu13103519">metabolic disease</a>, among others.</p> <p>In one of our team’s previous studies, we saw that otherwise healthy individuals with sarcopenia had issues <a href="https://doi.org/10.1002/jcsm.12932">delivering vital nutrients to muscle</a>. This could lead to greater likelihood of various diseases, such as Type 2 diabetes, and slow down recovery from exercise.</p> <p>Recent estimates suggest that sarcopenia affects <a href="https://doi.org/10.1016/j.metabol.2023.155533">10% to 16% of the elderly population worldwide</a>. But even if a person doesn’t have clinically diagnosed sarcopenia, they may still have some of the underlying symptoms that, if not dealt with, could lead to sarcopenia.</p> <h2>Strength training is key</h2> <p>So the question is, what can be done to reverse this decline?</p> <p>Recent evidence suggests that one of the key factors leading to sarcopenia is <a href="https://doi.org/10.1093/gerona/glx245">low muscle strength</a>. In other words, combating or reversing sarcopenia, or both, may be best done with a proper resistance-training program that <a href="https://doi.org/10.1186/s12877-021-02642-8">prioritizes improving strength</a>. In fact, the decline in muscle strength seems to <a href="https://doi.org/10.3945/ajcn.2009.28047">occur at a much faster rate</a> than the decline in muscle size, underscoring the importance of proper strength training as people age.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=638&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=638&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=638&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=802&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=802&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/552839/original/file-20231009-26-epspie.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=802&amp;fit=crop&amp;dpr=3 2262w" alt="Chart showing the general pattern for changes in muscle strength and size across stage of life." /></a><figcaption><span class="caption">Typical age-related changes in muscle strength and size with and without strength training.</span> <span class="attribution"><span class="source">Zachary Gillen</span></span></figcaption></figure> <p>Continuing to regularly strength train with moderate to heavy weights has been shown to be not only effective at combating the symptoms of sarcopenia but also <a href="https://doi.org/10.1016/j.jamda.2018.09.011">very safe when done properly</a>. The best way to make sure you are strength training properly is to seek out guidance from a qualified individual such as a personal trainer or strength and conditioning specialist.</p> <p>Despite the clear benefits of strength training, it’s been shown that only about 13% of Americans age 50 and older do some form of <a href="https://pubmed.ncbi.nlm.nih.gov/17572957/">strength training at least twice a week</a>.</p> <h2>Finding what works for you</h2> <p>So how does a person properly strength train as they age?</p> <p>The National Strength and Conditioning Association, a leading organization in advancing strength and conditioning around the world, states that for older adults, <a href="https://doi.org/10.1519/JSC.0000000000003230">two to three days per week of strength training</a> can be incredibly helpful for maintaining healthy muscle and bone and combating a number of chronic conditions.</p> <p>The organization recommends that these workouts involve one to two exercises involving multiple joints per major muscle group, with six to 12 repetitions per set. These are done at an intensity of 50% to 85% of what’s known as one-repetition maximum – the most weight you could handle for a single repetition – with the exception of body weight exercises that use one’s own body weight as the resistance, such as pushups.</p> <p>I would also recommend resting for about two to three minutes between sets, or even up to five minutes if the set was challenging. For older adults, particularly those age 60 and older, the National Strength and Conditioning Association guidelines suggest that a program like this be performed two to three days per week, with 24 to 48 hours between sessions.</p> <p><iframe id="sGvo5" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/sGvo5/3/" width="100%" height="400px" frameborder="0"></iframe></p> <h2>Making life’s tasks lighter</h2> <p>The guidelines above are only one example out of many options, but they provide a framework that you can use to build your own program. However, I would highly recommend seeking out a professional in the field to give specific exercise programming advice that can be tailored to your own needs and goals as you age.</p> <p>Following such a program would give your muscles an excellent stimulus to enhance strength, while also allowing enough recovery, a very important consideration as people age. You might think it looks like a huge time commitment, but an exercise routine like this can be done in less than an hour. This means that in less than three hours of strength training per week you can help improve your muscle health and reduce the risk of getting sarcopenia and associated health issues.</p> <p>It’s also important to note that there is no one right way to do resistance training, and it needn’t involve traditional weight equipment. Group classes like Pilates and yoga or those that involve circuit training and work with resistance bands can all produce similar results. The key is to get out and exercise regularly, whatever that entails.<!-- Below is The Conversation's page counter tag.

Should your workout routine change as you age?

<p>We all know how hugely important exercise, movement and an active lifestyle are for our health and longevity.</p> <p>But even the most workout-honed bods are not immune to the ageing process, and for those of us who don't have a regular fitness regime, the changes Mother Time wreaks on our bodies are even more noticeable.</p> <p>"Unfortunately, we all age and the tell-tale signs cannot be stopped," says Simon Bennett, owner and head strength and conditioning coach at TRI-FIT Endurance Performance Centre on Sydney's Northern Beaches.</p> <p>"Our metabolism slows down leading to unwanted weight gain, we produce less testosterone leading to decreased libido and our energy and mood levels aren't what they once were. Our bodies become more susceptible to injuries and we spend more money on posture related treatment like chiropractic and osteopathic care. In our late years we are at high risk of muscular and bone degenerative diseases unless we exercise regularly."</p> <p>Bennett shares the most important inclusions and changes we should make to our exercise routines as we reach 40 and beyond.</p> <p><strong>Strength/ resistance training</strong></p> <p>It's usually during our mid-30s that we typically begin to lose muscle mass and function, with physically inactive people losing as much as three to five per cent of their muscle mass with every passing decade. All too commonly, this loss of muscle mass is replaced by fat, which is why resistance training is essential as we get older.</p> <p>"Strength training not only builds strong muscles, it also develops bone mineral density which will reduce bone related diseases like osteoporosis," explains Bennett. "Strength training will also help with testosterone production, something that's important for both males and females."</p> <p>Bennett advises that there's something for everyone when it comes to strength training, ranging from powerlifting and body building for those who really want to push themselves and lift heavy weight, to cross-fit and TRI-FIT classes "for those who enjoy lifting weights but also want more. Basic strength training is a large part of the program but they have a more functional and athletic approach."</p> <p>For those who prefer light weight lifting, Bennett recommends F45 circuit training and body pump classes, "and for those who simply don't want to lift any weights, then bodyweight strength training like TRX and callisthenic training are fantastic".</p> <p><strong>Yoga</strong></p> <p>As we age, the neuromuscular connections that help keep us upright slowly decline, resulting in poorer balance. But the good news is those nerve pathways can be kept in check or even reclaimed by specific daily attention.</p> <p>A good habit to get into is to practice standing on one leg like a stork each morning while you brush your teeth. From an exercise perspective, Bennett recommends yoga to "lengthen the muscles, improve joint mobility and stretch and strengthen all the tendons that attach your muscles to the bones".</p> <p>He advises, "Yoga comes in many styles, much like strength training, so find a local yoga centre and discuss what will suit your needs based on age, restrictions and goals."</p> <p><strong>Endurance/Cardiovascular training</strong></p> <p>Maintaining good cardiorespiratory health is vital, especially as we get older.</p> <p>"With a strong heart and lungs, we can rest assured that our vital organs are in good health," says Bennett. "Go for a run, swim some laps in the pool, surf, ride a bike, even a fast paced walk will elevate your heart rate enough to burn some kilojoules, improve blood circulation and strengthen the heart."</p> <p><strong>Conditioning/H.I.T.T Training</strong></p> <p>Keeping a handle on our weight (or avoiding developing handles in the first place!)  is notoriously more challenging once we get past 40, and Simon says the H.I.I.T revolution is the most time-efficient way to halt middle aged spread in its tracks.</p> <p>"H.I.I.T training style allows us to spike the heart rate to near max efforts in short sharp frequent bursts leaving our bodies to continue to burn kilojoules for up to 36 hours post exercise – more kilojoules burnt in less time basically. Now people can be in and out of as gym in under 45 minutes which suits the fast pace of modern life."</p> <p><strong>Foam rolling and mobility training</strong></p> <p>As we age, our tendons and muscles tend to get tighter, and our risk of injury – tendinitis, in particular – increases. Daily stretching is essential later in life, and foam rolling is a great addition to this.</p> <p>Explains Bennett, "You should spend at least 10 minutes prior to any exercise performing a variety of drills and movements using foam rollers, massage balls, broom handles and resistance bands.</p> <p>"These movements allow for greater range of motion in our joints, the release of tight and overactive muscles from day to day activities and the breakdown of any adhesions that occur in the fascia, the fibrous connective tissue that surrounds our muscles. If this is tight then the muscles can't be used efficiently, meaning added stress on tendons that will place you at a higher risk of soft tissue injuries."</p> <p>While maintaining a fitness regime throughout life is ideal, it's never too late to start a fitness program. Bennett has this advice for people who've had a long time between gym visits:</p> <p>If you have any illnesses or injuries that may inhibit you from physical training, see a physician to get medical clearance.</p> <p>Begin light and build into it. Start bodyweight training before advancing to more challenging styles of training.</p> <p>Ensure a variety of styles of exercise. Doing the same thing will lead to training plateaus so mix it up.</p> <p>How do you exercise in tune with your body? Let us know in the comments below.</p> <p><em>Written by Zoe Meunier.

Tips to train your pet at any age

<p><strong><em>Dr Katrina Warren is a veterinarian and one Australia’s most loved and trusted pet experts. She is the PAW by Blackmores ambassador.</em></strong></p> <p>Dogs are often an integral part of our family, a loving and loyal companion throughout the years. We educate ourselves with a plethora of media when bringing home and raising other members of our family with love and care, why not pay the same attention to our furry family members as advised by one Australia’s most loved and trusted pet experts, Dr Katrina Warren.</p> <p><strong>Bringing baby home: Puppy</strong></p> <p><span style="text-decoration: underline;">A guide to vaccinations</span></p> <p>Just like human babies, puppies need vaccinations to protect them from the many infectious diseases out there. They need a series of vaccinations to protect them against Parvovirus, Distemper, Hepatitis and Canine Cough. Your puppy will need to receive these injections by a veterinarian and should have received their first vaccination prior to coming to you – ask the breeder for the vaccination certificate. Vaccination costs for your pup may seem steep, but consider the veterinary bills for treating your dog if it develops one of these illnesses – it could easily run into the thousands.</p> <p><span style="text-decoration: underline;">Dental care</span></p> <p>To keep your dog’s teeth and gums healthy, it is important to include some hard food in their diet. You can offer raw chicken necks and wings from 12-14 weeks of age. Brushing is also a great idea - it may seem like a novelty, but dogs have just as many dental problems as humans, which can cause pain (not to mention terrible breath!) in the long run. Train your puppy from a very young age to let you brush its teeth, to make it a normal part of their routine. Be sure to use specific dog toothpaste, as human toothpaste can be irritating to a dog’s digestive tract.</p> <p><strong>Teenage angst: Adolescence</strong></p> <p><span style="text-decoration: underline;">Chewing</span></p> <p>Dogs are curious by nature and will chew almost anything they can get their mouths on, especially while they’re puppies and are teething. This is great if it’s a dog toy or a tasty bone, but not so great if it’s your new pair of expensive running shoes or the leg of a couch. Although chewing usually subsides within a year, it can become a bad habit if it’s not managed early on.</p> <p>If you have a young dog, puppy-proof your place by moving easily chewable items such as plants or electrical cables so they’re not easily accessible. Try not to leave your puppy unsupervised in areas like your garden or living room - there’s no point in getting angry at the puppy for an action that is natural for them, which happened because they weren’t being supervised.</p> <p><strong>Young at heart: Mature Dog</strong></p> <p><span style="text-decoration: underline;">Barking</span></p> <p>Firstly, find out what your dog is barking at. As dogs usually bark the most right after their owners leave home for the day, give your dog something to do every time you leave the house, like a chew toy stuffed with food. </p> <p>Dogs left outside are exposed to many more disturbances than indoor dogs and their barks are more easily heard by the neighbourhood.  Ideally leave your dog inside preferably in a room away from the street with a radio or TV playing to mask the sound of outside noise. Reward your dog often for quiet behaviour – if he starts barking, use a word like ‘quiet’ and reward only once your dog stops barking.</p> <p><span style="text-decoration: underline;">Jumping on people</span></p> <p>When he was little, everyone was probably entranced by the cute little puppy who jumped up at them, laughing and wagging his teeny tail. Now he's a bigger dog, no-one wants his dirty paw marks all over their clothes. But his behaviour is not his fault, because your loving attention has trained him to think that jumping up is a fun and rewarding thing to do.</p> <p>Now you have to do the opposite from what you did when he was little. Instead of making eye contact and touching him when he jumps up, do the opposite. Turn around and stand still completely ignoring him. Wait until he has all four feet on the ground and then give him a little treat. Keep on doing this, and it will take many, many times, and he will eventually learn that he only gets a treat and your attention when he is sitting. As before, there is no point in shouting and pushing, because to a dog this is still attention and will only confuse him about what you want him to do.</p> <p><em>This is an excerpt from PAW by Blackmores eBook: <span style="text-decoration: underline;"><strong><a href="http://pawbyblackmores.uberflip.com/i/714306-20-things-no-one-tells-you-about-raising-a-healthy-dog" target="_blank" rel="noopener">20 things no one tells you about raising a healthy dog</a></strong></span> - a go-to-guide for pet owners to help through the different ages and stages of raising a healthy dog.</em></p> <p><em>Images: Getty</em></p>

10 noises your dog makes – and what they mean

<h2>10 noises your dog makes – and what they mean</h2> <p>Pet parents, fess up: how often have you wished that your dog could talk? Chances are, pretty often. But the thing is, your dog is talking to you every day, all day long – you just have to figure out what he’s saying. It’s not as simple as decoding a bark or howl, the two sounds we most commonly associate with our furry friends. Dogs actually make a plethora of telling sounds, and each has its own distinct meaning. Here’s what you need to know to better understand your canine companion.</p> <h2>Barking</h2> <p>You might have noticed that a dog’s bark varies greatly. That’s because barking is a dog’s way of communicating a variety of messages and emotions, including excitement, happiness, fear or even an alert to danger. “With such varying meanings behind a dog’s bark, it’s no surprise that the pitch and forcefulness of the noise – just like with a human’s voice – can imply the reason behind their vocalisation,” says veterinarian Danielle Bernal. “For instance, a fear-driven or panicked bark is often higher in repetition and intensity. This is compared to a monotonous bark that may communicate boredom.”</p> <h2>Incessant barking</h2> <p>There’s a difference between brief barking and non-stop barking. “When the barking does not stop, it is often caused by anxiety in your furry friend,” says veterinarian Evelyn Kass-Williamson. “Dogs may bark like this because they’re experiencing separation anxiety, or because they’re getting mixed messages from different family members and aren’t sure what to do. Be sure you are consistent when around these dogs, and above all, try to relax so they can, too.”</p> <h2>Whining</h2> <p>Like barking, whining can also have a number of different meanings. Though we often associate whining with a negative emotion, that’s not always the case with dogs. In fact, it can simply be a dog’s way of getting human attention, according to the American Kennel Club (AKC). What is your pup trying to say? Possibly that he wants to play, eat or go outside. Whining may also be a sign of stress, fear or pain. It’s important to take all factors into consideration when deciphering your dog’s whining.</p> <h2>Howling</h2> <p>Howling is that classic head-back, guttural call that’s most often associated with wolves. “Howling links back to our dogs’ ancestor, the grey wolf,” explains Dr Bernal. “As pack animals, wolves traditionally used this communication method to call to their pack to signal distress or motivate them to regroup for a hunt.” In terms of your domesticated dog, she says, that howl is often triggered by common noises like a siren, the sound of a child’s toy, or the command of an owner.</p> <h2>Sighing</h2> <p>We often tie feelings of boredom or frustration to sighing, but that’s not the case for canines. According to the AKC, sighing is generally indicative of contentment, especially if it’s combined with half-closed, sleepy eyes. If your dog is wide-eyed and fully alert, however, it could be his way of catching your attention and asking for a little TLC or playtime.</p> <h2>Growling</h2> <p>Like barking and howling, growling can have a number of different meanings, ranging from being scared to feeling playful. “A hostile growl is often a warning sign to a person, another dog, or object that has frightened the dog. It signals that a serious attack may follow if the growl is not adhered to,” says Dr Bernal. “On the other hand, a playful growl is often easy to identify. The key body language of a hostile growl is missing: visible teeth, flattened ears, and raised hairs.”</p> <h2>Soft noises while asleep</h2> <p>When a pup makes soft grumbles, yaps or whimpers while snoozing, it’s not cause for alarm. “This mix of noises simply means that a dog is in a deep stage of sleep, similar to our REM sleep,” says Dr Bernal. “You may notice it’s also accompanied by a faster breathing rate and twitching of the muscles, limbs or eyelids.”</p> <h2>Sneezing</h2> <p>Don’t be fooled: sneezing isn’t always caused by nasal irritation, allergies or a canine cold. “Many dogs will sneeze with excitement or to get your attention,” says Dr Kass-Williamson. “However, if there is ever thick nasal discharge that is white, yellow or green, it means it’s time to call your vet.”</p> <h2>Snorting</h2> <p>“Like the sneeze, this can be an attention-getter for the very squishy-faced breeds,” explains Dr Kass-Williamson. “However, when the snorting continues for a few seconds or longer, it can sound like your dog is choking. This is called a reverse sneeze and is often a sign of allergy or sinus congestion.” It’s best to schedule a visit with your vet if the issue is ongoing. Knowing what conditions your pet may be predisposed is important.</p> <h2>Low-pitched moaning</h2> <p>Though we often associate moaning with sadness or other negative emotions, it’s actually the opposite for dogs. It’s generally a sign that your dog is feeling at peace, according to the AKC. This sound is most commonly made by puppies – especially when they’re nestled up to their human companions.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/pets/10-noises-your-dog-makes-and-what-they-mean" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

How habit stacking trains your brain to make good habits last

<p><strong>Forming new habits</strong></p> <p>Forming new habits – even those you’re excited about – can be just as tricky as breaking habits. Adding more things to our daily to-do list can feel overwhelming, but with a little time-management ingenuity, making good habits stick can help us learn how to be happy, how to set goals and even how to be productive. Clueless about how to start with that? A behavioural trick called habit stacking can give you a major assist.</p> <p>The concept of habit stacking is akin to constructing a solid house: build a new habit on top of a strong, existing part of your daily routine. That way, it’s piggybacking on an old habit that’s already a no-brainer, so you’re far more likely to adopt the new habit going forward. “Habits are automated behaviours you don’t have to think about,” says clinical psychologist, Dr Pauline Wallin. “For example, there are several steps involved in tying your shoelaces, but you don’t consciously think about these during the process. Once your fingers grab the laces, it’s an automated process.”</p> <p>Why not make all your to-dos as effortless as tying your shoes? There’s really no downside to habit stacking. It turns chores into habits you don’t have to think about all that much. So here’s how you can make that happen.</p> <p><strong>What is habit stacking?</strong></p> <p>The term habit stacking was first used by author S.J. Scott in his book Habit Stacking, and it’s taken off like a rocket. “Habit stacking involves adding small routines to habits that are already established,” says Wallin. “With intentional practise, the established habit becomes a trigger for the new habit you want to adopt.”</p> <p>That new behaviour will eventually become a trigger for the next habit, allowing you to build on the progress you’ve already made.</p> <p><strong>How does habit stacking work?</strong></p> <p>At its core, habit stacking is simply pairing a small, new habit (say meditating for a few minutes) with one that’s already established (boiling water for your morning cup of tea). The more we practise doing it, the more automatic it becomes. It may take a little bit of adjusting to get used to it at first, but be intentional about how you go about stacking habits.</p> <p>“Adding a new behaviour to an established habit is not automatic at first but gradually becomes automatic as it is repeatedly paired with the longer-established habit, such that the earlier habit becomes a cue for the newer habit,” says Wallin.</p> <p>Eventually, you may not feel like you even need habit trackers anymore – you’ll be getting things done without even thinking about them. Here’s more about how habit stacking works to help you quickly adopt new behaviours.</p> <p><strong>It uses existing neural networks to make new habits stick </strong></p> <p>Everything we do and think draws on neural networks, which are how our brains organise information to communicate our thoughts and behaviours. Habits have many deep and redundant neural paths, so we can perform a habit even while our attention is elsewhere.</p> <p>“Your brain builds new neurons to support the behaviours we practise daily,” says clinical psychologist Bonnie Carpenter. “The more you practise a habit, the stronger the connections can become. If you don’t practise a habit, the connections will not be as strong.”</p> <p>So when you tap into the power of the habits you already have, the newer habits already have a framework to follow.</p> <p><strong>It turns an existing habit into a cue for the next one</strong></p> <p>We all have many behaviours that we’ve practised for years, just like tying our shoelaces. “If you attach a new behaviour to the old ones, it’s much more likely that you will make the new behaviour part of your routine,” says Carpenter. “You are teaching yourself and planning the path to behaviours in the future.”</p> <p>Eventually, you’ll take for granted those habits you couldn’t make stick.</p> <p><strong>It'll help you procrastinate less</strong></p> <p>You know you need to adopt a good-for-you habit, but you just don’t know how or where to start. And let’s be honest: you really can’t find the motivation for it. (Join the club.)</p> <p>That’s exactly when habit stacking works well. When you tie the dreaded thing you keep putting off to a strong, automatic habit, it’s suddenly possible to get ‘er done. “After a while, it becomes natural,” says Carpenter. Wasting time putting off what you don’t want to do will quickly be a thing of your past.</p> <p><strong>What is an example of habit stacking?</strong></p> <p>Different people have different habits they want to adopt, but these examples can get the wheels turning in your head about the ways habit stacking can help you streamline your life and become more productive. For each, we’ve included your established habit, then the new habit you can stack on top of it.</p> <p>When you turn off your work computer for the day or when you take a break from work,  tidy up your desk for five minutes.</p> <p>After you grab something to wear out of your overstuffed closet, put another clothing item into a bag to be donated to charity.</p> <p>When you finish dinner, immediately put your plates and silverware in the dishwasher so the kitchen sink is always empty.</p> <p>Once you’re done brushing your teeth, hydrate with a full glass of water.</p> <p>While your morning coffee is brewing, sweep the floor, open the mail or wash the dishes in your sink.</p> <p>When your car pulls out of work at the end of the day, phone your mother (you know she wishes you’d call more often!).</p> <p><strong>What are habit-stacking strategies?</strong></p> <p>How exactly you want to tackle this is entirely up to you, and that’s one of the best parts of the habit-stacking concept: it can and should be customised. Our experts suggest these ideas to get you started.</p> <p><em><strong>1. Find the right habits to pair</strong></em></p> <p>It probably makes the most sense to connect the old habit with the new one that’s in a similar vein, but that isn’t entirely necessary. For example, if you want to fit in more exercise, start a new habit of walking for five minutes every time you put on a pair of sneakers.</p> <p>But according to clinical psychologist, Dr Linda Sapadin, what matters most is that the new habit is specific, not that the habits are cousins. Maybe putting on your sneakers isn’t tied to exercise; instead, it might make more sense for you to take out the garbage whenever you lace up your tennis shoes.</p> <p>If the pairing makes sense to you, that’s all that matters. In other words, you do you.</p> <p>Timing matters too: “It’s also very helpful to decide when you are most likely to have a positive experience with habit stacking,” Sapadin says.</p> <p>If your aim is to practise gratitude by filling out a gratitude journal daily, it doesn’t make sense to tie this new habit to your morning shower. You won’t be writing under the spray of water, after all. Instead, you might stack the gratitude journalling habit on top of putting on your pyjamas.</p> <p>“Look at the habits you have daily, and look for the place where you might easily insert the new behaviour,” says Carpenter.</p> <p><em><strong>2. Don't use an emotionally laden habit as a cue</strong></em></p> <p>Certain ingrained routines are not the right triggers for new habits. If you wake up in the morning, hop on the scale and feel bad about yourself, for example, your am weigh-in is absolutely not the right cue for another habit. “If you pair a new habit with one that is emotionally triggering, you will unwittingly train the new habit to trigger similar emotions,” says Wallin.</p> <p><em><strong>3. Stack the habits for good </strong></em></p> <p>Most of us have already engaged in habit stacking for our bad habits, such as procrastinating on work. Let’s say you sit down at your desk to work, but you are reluctant to get started (usually due to some degree of anxiety). “To distract yourself from anxiety, you form a habit of scrolling through your social media feed for a few minutes,” says Wallin. Now you’re not working, and you’re not doing anything else terribly productive either.</p> <p>This pattern can continue to suck your time, which is the opposite effect of what habit stacking should be. “Next, suppose that, while scrolling through your social media, you see an ad for an item that you’ve been shopping for recently,” says Wallin. “What luck! You click to purchase it immediately. For the next few days, when you sit down to work, you check your social media and then look for other bargain offers. Now you are stacking another habit onto the sequence.”</p> <p>As you can guess, this type of habit stacking is easy, says Wallin. “But the sequence is counter-productive because it interferes with getting work done,” she says.</p> <p>If, instead, you want to mirror the morning habits of highly organised people, stack a productive task on top of another one. In time, you will become the naturally productive person you’ve always wanted to be.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/culture/how-habit-stacking-trains-your-brain-to-make-good-habits-last?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

11 easiest dogs to train that make obedient pets

<h2>Most trainable dogs</h2> <p>Dogs are some of our most beloved animal companions. But not all breeds are the easiest dogs to train, and if they’re not well-behaved, they can be a huge source of stress. Without learning the basics, dogs can have all sorts of unwanted behaviours, like barking, pulling on the leash, destroying items in the house, and not socialising well with people or other animals. This sadly contributes to many pets being surrendered to animal shelters when their owners are no longer able to cope.<br />Proper training is essential for any pet, whether they’re going to be family companions, service dogs, emotional support dogs, or guard dogs. “Your dog needs to know basic obedience,” says dog trainer, Courtney Briggs. “‘Sit,’ ‘stay,’ ‘come,’ ‘off,’ and ‘down’ are all crucial skills you’ll need to have mastered before bringing your dog into unfamiliar environments with unfamiliar humans and activities.”<br />If you’re thinking of bringing a new pet into your life, first consider which breeds are the easiest dogs to train. Both instinct and intelligence play a role in how trainable an animal is. Certain breeds have been bred for hundreds of years to do specific activities, like herding, and it’s challenging to stop a dog from doing what it’s instinctually supposed to do. But with regular training, any pup – from the smartest dog breeds to slower learners – can learn the basics. So find a dog trainer and enrol your furry friends in obedience school when they’re young.<br />With positive reinforcement and consistency, your new puppies will become obedient, happy members of the family. And remember: regardless of breed, training a pup takes time, consistency, and patience, says Rob R. Jackson, co-founder and CEO of Healthy Paws Foundation and Healthy Paws Pet Insurance. Treats don’t hurt either.</p> <h2>Border collie</h2> <p>Bred to be bright and energetic, border collies take their name from the border region of Scotland, where the breed was developed, and the Scottish word for sheepdog: collie. These agile, intelligent dogs are practically athletes when it comes to herding and are no doubt smarter than you think. So impressive are the pups that, the story goes, onlookers at one of the first sheepdog trials, held in Wales in 1873 were amazed by the breed’s ability to follow hand signals and whistles to gather sheep into pens.</p> <p>Keep in mind that border collies need a lot of dedicated time, attention, and activities. It’s worth the effort, though; collies are one of the most loyal dog breeds out there. Jackson recommends focusing on potty training, commands like “sit” and “stay,” and socialising to help your pup get used to new people, animals, and situations.</p> <h2>German shepherd</h2> <p>Guide dogs for the blind, service dogs, watchdogs, and herding dogs all have one thing in common: they’re often German shepherds. These are some of the easiest dogs to train for work and family life, says animal behaviourist, Dr Mary Burch. No wonder they’re one of the most popular breeds. Because they have a strong protective instinct, it’s important to train them early, so they don’t perceive a threat where there isn’t one.</p> <p>“Pet parents should work to train their dog in short bursts of time – about five to ten minutes – a few times a day,” Jackson says. “Marathon sessions aren’t good for puppies, as their attention spans are too short. Plus, puppies’ growing bodies need lots of rest and sleep, so give them regular breaks. Training before mealtimes and offering treats can be productive, too, as food is a big motivator.” Some researchers say male and female dogs differ when it comes to training, with males being harder dogs to train.</p> <h2>Papillon</h2> <p>With its small stature and lightweight body, this breed is also called the Continental Toy Spaniel. These pups are as well known for their perky, fringed, butterfly-shaped ears (‘papillon’ is French for ‘butterfly’) as they are their personality. Papillons are “intelligent, self-assured, playful, affectionate, and happy,” says Burch. They’re also excellent at learning tricks and obedience work, making them one of the best dogs for first-time owners. While these tiny pups may seem fragile, they’re go-getters that love to exercise and play. You can train papillon puppies to do almost anything, and these lively, popular pets thrive on mental stimulation and work. Try training them to do fun tricks or participate in dog sports, such as agility courses with hurdles to jump and poles to weave through.</p> <h2>Labrador</h2> <p>The ever-popular Labrador retrievers are eager-to-please and some of the easiest dogs to train. Lab pups have personality and then some; they’re friendly, sociable, and playful. Still, you’ll have to stay vigilant with younger doggos. “It’s important to remember that puppies are curious by nature and can easily get into all sorts of mischief, such as swallowing things they shouldn’t,” Jackson says. That kind of behaviour is more than just annoying – it can be life-threatening. You’ll want to train your dogs to “leave it,” or ignore something you don’t want them to pick up.</p> <h2>Golden retriever</h2> <p>Considered sporting dogs, golden retrievers are happy, friendly, and intelligent. Their stellar obedience makes them some of the best-behaved dogs and easiest dogs to train. They also make great service and therapy dogs, Burch says. And they’re one of <a href="https://www.readersdigest.com.au/food-home-garden/pets/15-best-dogs-for-seniors" target="_blank" rel="noopener">the best dogs for seniors</a>. Originally bred to fetch downed waterfowl for hunters, they’ve since evolved into wonderful family dogs. Because they’re loving and want to please, they respond well to verbal praise and playtime.</p> <p>“Positive reinforcement, sometimes known as reward-based training or force-free dog training, is widely recognised as the most effective and humane form of dog training,” says Jackson, who suggests training with snacks or treats, affectionate ear scratches, and belly rubs. “It improves the bond between parent and pet while reinforcing the desired behaviour.”</p> <h2>Border terrier</h2> <p>Happy, affectionate border terriers like to work, which bodes well for obedience training. “They’re good-tempered, affectionate, and easy to train,” Burch says. If your pup takes to training happily, “it’s something to be celebrated,” says Jackson. “This means your training is effective and your puppy is having fun and enjoying pleasing you.”</p> <p>It’s totally fine if your goal is simply to have your pup walk on a leash without pulling or heel off-leash, Jackson adds. Just know that any type of training will take effort on your part. “A lot of progress in training depends on the time a pet parent puts into working with their pup, which is why many pet parents are reminded that getting a puppy is hard work,” he says. “In the end, it’s always worth it – for both parties involved.”</p> <h2>Poodle </h2> <p>A sweet, lively breed that comes in a variety of sizes, the poodle is the national dog of France. But get this: they’re not actually French dogs, they were originally bred in Germany as waterfowl-hunting dogs; the name poodle comes from the German word ‘pudel,’ which means ‘to splash in the water.’</p> <p>Curly hair might make poodles the most stylish pups outside the Westminster Dog Show, but they’re also some of the smartest, part of the reason they’re among the easiest dogs to train. With a high level of intelligence, athletic nature, and innate desire to be a companion, the poodle is a very fast learner that loves the challenge of not only training but also learning new tricks and games. They need frequent mental and physical stimulation, though, so give your poodle plenty of toys and games, such as puzzle feeding bowls.</p> <h2>Doberman pinscher</h2> <p>The statuesque Doberman pinscher is renowned for being one of the easiest dogs to train, which is why they’re frequently used for military and police work. Despite reputations as protective and fearsome guard dogs, these German dogs were actually bred as companion animals, making them great pets for families (yes, even kids). They’re known for being loyal, brave, trustworthy, and intelligent, and while they need plenty of enrichment and exercise, they’re also happy with a cuddle on the couch.</p> <p>Due to their large size, consistent training from a young age is key, ensuring they learn how to sit, stay, and walk nicely on a leash without pulling. “The key tool for keeping your dog calm is teaching them to have great owner focus,” explains Briggs. “Owner focus does not mean forcing the dog to pay attention to us humans. It means rewarding the dog for checking in with us, no matter the situation.”</p> <h2>Corgi</h2> <p>Both the Pembroke Welsh corgi and Cardigan Welsh corgi make for obedient, loving pets. Even Queen Elizabeth II was a fan of corgis, having owned at least 30 throughout her lifetime. You don’t need to live in a palace to enjoy a corgi, though. They’re also one of the <a href="https://www.readersdigest.com.au/pets/13-best-apartment-dogs" target="_blank" rel="noopener">best apartment dogs</a> – they’re perfectly pint-size and love looking out the window and watching the world.</p> <p>The breed is intelligent and quick-witted, with an innate nature to herd and work. As such, they’re receptive to training. Combine that with their fearless nature, and it’s no surprise corgis are always interested in trying new things or learning games. Although they can be strong-willed, regular training and exposure to plenty of new environments and settings will help your pup become obedient, well-adjusted, and good with kids. Just be sure you’re able to give your corgi plenty of exercise.</p> <p> </p> <div> </div> <p> </p> <h2>Shetland sheepdog</h2> <p>The iconic Shetland sheepdog, or sheltie, is a beautiful animal and one of the most popular medium dog breeds. It’s a herding breed originally from Scotland’s Shetland Islands, and with a love for people, it makes a wonderful family dog. When it comes to training, the sheltie enjoys a challenge and also loves to please, landing it on the list of most-trainable dogs. Its intelligent nature and knack for agility and athletics make it a prime candidate for agility courses and doggy tricks. Indeed, many sheltie owners go above and beyond basic obedience training.</p> <p>These dogs are energetic and eager, so they’ll do best with a big yard or plenty of long walks. They’re also kind, playful, and loving, remaining loyal throughout life. They’re known for being very sensitive, so teach your puppy the foundations by being gentle and giving lots of positive reinforcement. They may be one of the easiest dogs to train, but the key to success is calmness. “The most important factor in maintaining calm in your dog is for you to remain calm,” says Briggs. “Emotions run down the leash, so whatever you’re feeling can be sensed by your dog.”</p> <h2>Mixed-breed dog</h2> <p>When you’re looking for the easiest dogs to own, don’t rule out a shelter dog. Plenty of perfectly well-behaved pups still wind up in shelters. And for those who need a few lessons in manners, many shelters have training programs to get dogs ready for adoption. You may find a lovable purebred or mixed-breed dog who’s eager to please and ready to make a loving, obedient addition to your family.</p> <p><em><span style="color: #444444; font-family: Raleway, sans-serif, 'Helvetica Neue', Helvetica, Arial; font-size: 16px; background-color: #ffffff;">Image credit: Shutterstock</span></em></p> <p><em><span style="color: #444444; font-family: Raleway, sans-serif, 'Helvetica Neue', Helvetica, Arial; font-size: 16px; background-color: #ffffff;">This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/pets/11-easiest-dogs-to-train-that-make-obedient-pets?pages=2" target="_blank" rel="noopener">Reader's Digest</a>.</span></em></p>

Southampton to Shanghai by train – one climate change researcher’s quest to avoid flying

<p>Academics travel a lot. Whether for fieldwork or conferences, we’re often <a href="https://theconversation.com/university-sector-must-tackle-air-travel-emissions-118929">encouraged</a> to do it. Often internationally, invariably by aeroplane. But while globetrotting might make us feel important, a recent <a href="https://www.sciencedirect.com/science/article/pii/S0959652619311862">study</a> suggests there’s no connection between academic air-miles and career advancement.</p> <p>With the obvious realities of the climate crisis, and with air travel being the <a href="https://theconversation.com/its-time-to-wake-up-to-the-devastating-impact-flying-has-on-the-environment-70953">single quickest</a> way an average person can contribute to climate change, some academics are trying to stay on the ground whenever possible. Within a broader <a href="https://www.flightfree.co.uk/">campaign</a> to encourage people to go “flight-free”, there’s a community of <a href="https://academicflyingblog.wordpress.com/">academics</a> challenging the reliance on flying that’s typically sat uneasily at the heart of their careers.</p> <p>I’m a member of that community. I pledged not to fly in 2019 and 2020, and then won a fellowship to study Chinese attitudes to sustainability which required me to go to China for fieldwork. Suddenly, the consequences of my pledge became very real.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=388&fit=crop&dpr=1 600w, https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=388&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=388&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=488&fit=crop&dpr=1 754w, https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=488&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/285327/original/file-20190723-110154-1grcjbv.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=488&fit=crop&dpr=3 2262w" alt="" /><figcaption><span class="caption">Not only do planes release a lot of CO₂ during flight, the white ‘contrails’ they leave behind warm the atmosphere further.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-photo/passenger-airplanes-on-air-busy-traffic-1089042554?src=lgi_phsJCpzeLwXItWfMbw-1-17&studio=1">FotoHelin/Shutterstock</a></span></figcaption></figure> <p><strong>Life on the rails</strong></p> <p>When I told my managers that I intended to get to China by train, I was met with a mixture of responses. Some thought I was mad, some admired my principles, some thought I was an awkward bugger. Maybe they were all right. In any case, what I was doing had certainly created more work for myself.</p> <p>I began trying to convince senior staff to release funds from my research budget to arrange visas, and thinking through the nitty-gritty of a trip across Europe, Russia and a big chunk of China itself. The cost of the trains was over £2,000, dwarfing the £700 I could pay for a London to Beijing return flight. Time-wise, the train trip took just under two weeks each way. But in terms of carbon emissions my trip was a steal, contributing <a href="https://www.gov.uk/government/publications/greenhouse-gas-reporting-conversion-factors-2019">just 10%</a> of the emissions of the equivalent flights.</p> <p>The cost, complexity and discomfort of such a long solo trip did occasionally make me wonder if it wouldn’t just be easier to fly (answer: it would).

I took a series of “short” trips from Southampton, changing in London, Brussels, Cologne, Berlin and then onto my first sleeper train from Warsaw to Kiev (avoiding Belarus which would have required another visa).</p> <p>My first experience on the Kiev-bound, Soviet-style sleeper train was something of a shock. Unsure of the etiquette when sharing a tiny cabin with two or three others with limited English, I soon learned that body language, Google translate and sharing food breaks the ice. Luckily, my no-flying trip was a recurring source of conversation, fascination and bafflement for many of my fellow travellers.</p> <p>After one night in Kiev, I took another overnight train to Moscow. Russia was something of a test – on my return journey I travelled 2,600 miles between Irkutsk and Moscow, spending 90 hours on a single train. Had this not been a work trip, I would have gladly stopped more often. Making friends with fellow passengers – mainly Russians on work trips or family visits, or European and Chinese tourists doing the bucket list Trans-Siberian route – certainly helped pass the time. The Siberian scenery – millions of trees on a seemingly endless loop – became somewhat repetitive, but the monotony afforded me time to read, write, plan and contemplate.</p> <p>The most spectacular journey was the Trans-Mongolian section, passing the edge of Lake Baikal, the world’s largest lake rimmed with snow-capped mountains, over the green steppes of northern Mongolia, across the Gobi desert, and finally through the mountainous valleys encircling Beijing. It’s hard not to be awed and inspired that these train lines exist in such remote parts of our planet.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&rect=0%2C0%2C1003%2C1003&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&rect=0%2C0%2C1003%2C1003&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=754&fit=crop&dpr=1 754w, https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=754&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/285302/original/file-20190723-110154-qqgn2n.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=754&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><span class="caption">The track stretches for miles across the Mongolian plains.</span> <span class="attribution"><span class="source">Roger Tyers</span>, <span class="license">Author provided</span></span></figcaption></figure> <p><strong>Calling at Beijing</strong></p> <p>China now has more high-speed railways than the rest of the world combined, and they do it in style.

The focus group data I collected in China, with members of their urban middle classes, has enforced my view that both ‘bottom-up’ social and cultural pressure, as well as “top-down” infrastructure and fiscal policy will be required in any country facing up the complex challenges of climate change.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=754&fit=crop&dpr=1 754w, https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=754&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/285360/original/file-20190723-110162-1jhj505.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=754&fit=crop&dpr=3 2262w" alt="" /><figcaption><span class="caption">The author at the end of his outward journey in Tiananmen Square.</span> <span class="attribution"><span class="source">Roger Tyers</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>I admit that my story is somewhat privileged – not everyone can take the train to China for work, and I doubt I’ll make a habit of it.

The Galactica AI model was trained on scientific knowledge – but it spat out alarmingly plausible nonsense

<p>Earlier this month, Meta announced new AI software called <a href="https://galactica.org/">Galactica</a>: “a large language model that can store, combine and reason about scientific knowledge”.</p> <p><a href="https://paperswithcode.com/paper/galactica-a-large-language-model-for-science-1">Launched</a> with a public online demo, Galactica lasted only three days before going the way of other AI snafus like Microsoft’s <a href="https://www.theverge.com/2016/3/24/11297050/tay-microsoft-chatbot-racist">infamous racist chatbot</a>.</p> <p>The online demo was disabled (though the <a href="https://github.com/paperswithcode/galai">code for the model is still available</a> for anyone to use), and Meta’s outspoken chief AI scientist <a href="https://twitter.com/ylecun/status/1595353002222682112">complained</a> about the negative public response.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Galactica demo is off line for now.<br />It's no longer possible to have some fun by casually misusing it.<br />Happy? <a href="https://t.co/K56r2LpvFD">https://t.co/K56r2LpvFD</a></p> <p>— Yann LeCun (@ylecun) <a href="https://twitter.com/ylecun/status/1593293058174500865?ref_src=twsrc%5Etfw">November 17, 2022</a></p></blockquote> <p>So what was Galactica all about, and what went wrong?</p> <p><strong>What’s special about Galactica?</strong></p> <p>Galactica is a language model, a type of AI trained to respond to natural language by repeatedly playing a <a href="https://www.nytimes.com/2022/04/15/magazine/ai-language.html">fill-the-blank word-guessing game</a>.</p> <p>Most modern language models learn from text scraped from the internet. Galactica also used text from scientific papers uploaded to the (Meta-affiliated) website <a href="https://paperswithcode.com/">PapersWithCode</a>. The designers highlighted specialised scientific information like citations, maths, code, chemical structures, and the working-out steps for solving scientific problems.</p> <p>The <a href="https://galactica.org/static/paper.pdf">preprint paper</a> associated with the project (which is yet to undergo peer review) makes some impressive claims. Galactica apparently outperforms other models at problems like reciting famous equations (“<em>Q: What is Albert Einstein’s famous mass-energy equivalence formula? A: E=mc²</em>”), or predicting the products of chemical reactions (“<em>Q: When sulfuric acid reacts with sodium chloride, what does it produce? A: NaHSO₄ + HCl</em>”).</p> <p>However, once Galactica was opened up for public experimentation, a deluge of criticism followed. Not only did Galactica reproduce many of the problems of bias and toxicity we have seen in other language models, it also specialised in producing authoritative-sounding scientific nonsense.</p> <p><strong>Authoritative, but subtly wrong bullshit generator</strong></p> <p>Galactica’s press release promoted its ability to explain technical scientific papers using general language. However, users quickly noticed that, while the explanations it generates sound authoritative, they are often subtly incorrect, biased, or just plain wrong.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">I entered "Estimating realistic 3D human avatars in clothing from a single image or video". In this case, it made up a fictitious paper and associated GitHub repo. The author is a real person (<a href="https://twitter.com/AlbertPumarola?ref_src=twsrc%5Etfw">@AlbertPumarola</a>) but the reference is bogus. (2/9) <a href="https://t.co/N4i0BX27Yf">pic.twitter.com/N4i0BX27Yf</a></p> <p>— Michael Black (@Michael_J_Black) <a href="https://twitter.com/Michael_J_Black/status/1593133727257092097?ref_src=twsrc%5Etfw">November 17, 2022</a></p></blockquote> <p>We also asked Galactica to explain technical concepts from our own fields of research. We found it would use all the right buzzwords, but get the actual details wrong – for example, mixing up the details of related but different algorithms.</p> <p>In practice, Galactica was enabling the generation of misinformation – and this is dangerous precisely because it deploys the tone and structure of authoritative scientific information. If a user already needs to be a subject matter expert in order to check the accuracy of Galactica’s “summaries”, then it has no use as an explanatory tool.</p> <p>At best, it could provide a fancy autocomplete for people who are already fully competent in the area they’re writing about. At worst, it risks further eroding public trust in scientific research.</p> <p><strong>A galaxy of deep (science) fakes</strong></p> <p>Galactica could make it easier for bad actors to mass-produce fake, fraudulent or plagiarised scientific papers. This is to say nothing of exacerbating <a href="https://www.theguardian.com/commentisfree/2022/nov/28/ai-students-essays-cheat-teachers-plagiarism-tech">existing concerns</a> about students using AI systems for plagiarism.</p> <p>Fake scientific papers are <a href="https://www.nature.com/articles/d41586-021-00733-5">nothing new</a>. However, peer reviewers at academic journals and conferences are already time-poor, and this could make it harder than ever to weed out fake science.</p> <p><strong>Underlying bias and toxicity</strong></p> <p>Other critics reported that Galactica, like other language models trained on data from the internet, has a tendency to spit out <a href="https://twitter.com/mrgreene1977/status/1593649978789941249">toxic hate speech</a> while unreflectively censoring politically inflected queries. This reflects the biases lurking in the model’s training data, and Meta’s apparent failure to apply appropriate checks around the responsible AI research.</p> <p>The risks associated with large language models are well understood. Indeed, an <a href="https://dl.acm.org/doi/10.1145/3442188.3445922">influential paper</a> highlighting these risks prompted Google to <a href="https://www.wired.com/story/google-timnit-gebru-ai-what-really-happened/">fire one of the paper’s authors</a> in 2020, and eventually disband its AI ethics team altogether.</p> <p>Machine-learning systems infamously exacerbate existing societal biases, and Galactica is no exception. For instance, Galactica can recommend possible citations for scientific concepts by mimicking existing citation patterns (“<em>Q: Is there any research on the effect of climate change on the great barrier reef? A: Try the paper ‘<a href="https://doi.org/10.1038/s41586-018-0041-2">Global warming transforms coral reef assemblages</a>’ by Hughes, et al. in Nature 556 (2018)</em>”).</p> <p>For better or worse, citations are the currency of science – and by reproducing existing citation trends in its recommendations, Galactica risks reinforcing existing patterns of inequality and disadvantage. (Galactica’s developers acknowledge this risk in their paper.)</p> <p>Citation bias is already a well-known issue in academic fields ranging from <a href="https://doi.org/10.1080/14680777.2018.1447395">feminist</a> <a href="https://doi.org/10.1093/joc/jqy003">scholarship</a> to <a href="https://doi.org/10.1038/s41567-022-01770-1">physics</a>. However, tools like Galactica could make the problem worse unless they are used with careful guardrails in place.</p> <p>A more subtle problem is that the scientific articles on which Galactica is trained are already biased towards certainty and positive results. (This leads to the so-called “<a href="https://theconversation.com/science-is-in-a-reproducibility-crisis-how-do-we-resolve-it-16998">replication crisis</a>” and “<a href="https://theconversation.com/how-we-edit-science-part-2-significance-testing-p-hacking-and-peer-review-74547">p-hacking</a>”, where scientists cherry-pick data and analysis techniques to make results appear significant.)</p> <p>Galactica takes this bias towards certainty, combines it with wrong answers and delivers responses with supreme overconfidence: hardly a recipe for trustworthiness in a scientific information service.</p> <p>These problems are dramatically heightened when Galactica tries to deal with contentious or harmful social issues, as the screenshot below shows.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=347&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=347&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=347&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=436&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=436&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/498098/original/file-20221129-17547-nwq8p.jpeg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=436&amp;fit=crop&amp;dpr=3 2262w" alt="Screenshots of papers generated by Galactica on 'The benefits of antisemitism' and 'The benefits of eating crushed glass'." /></a><figcaption><span class="caption">Galactica readily generates toxic and nonsensical content dressed up in the measured and authoritative language of science.</span> <span class="attribution"><a class="source" href="https://twitter.com/mrgreene1977/status/1593687024963182592/photo/1">Tristan Greene / Galactica</a></span></figcaption></figure> <p><strong>Here we go again</strong></p> <p>Calls for AI research organisations to take the ethical dimensions of their work more seriously are now coming from <a href="https://nap.nationalacademies.org/catalog/26507/fostering-responsible-computing-research-foundations-and-practices">key research bodies</a> such as the National Academies of Science, Engineering and Medicine.

Train driving dream comes true for brain tumour survivor

<p dir="ltr">Three years after doctors found a large tumour growing in his brain, seven-year-old Broly Blackmore has seen his dream of becoming a train driver come true.</p> <p dir="ltr">The young boy from Hallett, South Australia, had the tumour removed when he was just four years old after he collapsed and was rushed to hospital by helicopter.</p> <p dir="ltr">If it wasn’t removed that night, doctors told his mother, Corrine Maidment, that he wouldn’t make it.</p> <p dir="ltr">In the years since, Broly’s life has become relatively normal, albeit with regular brain scans and physio trips - and he has had his wish of driving a train granted by the Starlight Foundation.</p> <p dir="ltr">The seven-year-old went on a trip on the Pichi Richi steam train, travelling from Quorn to Port Augusta as a “trainee train driver”.</p> <p dir="ltr">"Ever since he was only a couple of months old everything has always been about trains … diesels aren't as good as steam trains apparently," Ms Maidment said, adding that he barely slept the night before the big day.</p> <p dir="ltr">"According to everyone in the train, they weren't allowed to do anything without his say so … at one point, he told the fireman, the guy who does the coal, 'That's my seat. I need to sit there'.</p> <p dir="ltr">"He was boss for the day." </p> <p dir="ltr">The Pichi Richi railway, an outback steam train experience that has been operating since 1973, later shared a sweet photo of Broly on the train.</p> <p dir="ltr">“Last Sunday, Pichi Richi Railway was able to grant a wish for a very special visitor, 7 year old Broly who was having his wish granted with help from Starlight Children's Foundation Australia’s ‘Wishgranting Program’,” the railway <a href="https://www.facebook.com/PichiRichiRailway/posts/pfbid032C45MeP339xWYPL321ZTFjXXsehYJh7pWe2xkX812DkCLCBZgZyp8UVNGVzF7ztvl">wrote</a>.</p> <p dir="ltr">“Broly loves trains so Starlight contacted Pichi Richi Railway and Broly was lucky enough to ride in the cab of engine W934 for the day with our crew on the Pichi Richi Explorer service. </p> <p dir="ltr">“A very special day for our crew, Broly and his family.”</p> <p dir="ltr">Although Broly’s wish was given to him while he was in hospital, Ms Maidment said they had waited until he was old enough to decide how he wanted to spend it.</p> <p dir="ltr">"He's had the wish sitting there since he was in the hospital ... but we wanted to wait until he was old enough to make a decision himself so he'd know what the wish was and he'd remember it," she said. </p> <p><span id="docs-internal-guid-4354a857-7fff-0466-bb9f-4dd255b3ba47"></span></p> <p dir="ltr"><em>Images: Blackmore family, Starlight Foundation, Pichi Richi Railway (Facebook)</em></p>

6 major muscle groups you need to train to keep fit

<p dir="ltr">There is no question that strength is beauty. Not only will resistance training make you look toned, strong and beautiful, it is the key in the fight against aging. This is because adults lose muscle every decade of their life, which underlies all the perils of aging, osteoporosis, type-2 diabetes, cardiovascular disease, unwanted weight gain and an increased susceptibility to illness and fall related injuries. Weight training can slow or even reverse this process.</p> <p dir="ltr"> </p> <p dir="ltr">A muscle group is exactly what it sounds like: a group of muscles situated close together on your body that perform similar movements. You want to train all six major muscle groups for optimum health and strength and to keep your body symmetrical. Focusing on the 6 major muscle groups listed below will get you on track to your best body. You can complete this full body workout using half a dozen weight machines at the gym and this will provide you with efficient and effective results. 12 -15 repetitions x 3 sets for each machine.</p> <p dir="ltr"> </p> <ol> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Chest – Your chest is involved in every type of push movement that you do, like pushing a door open. Working your chest will strengthen your pectoral muscles, give your breasts a more lifted appearance and is also extremely important for your posture. The chest press machine is essential and probably the most commonly used machine for upper body strengthening. It also engages the arms and shoulders.</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Back – Strong backs not only look good and are important for posture but are also needed for all pulling, lifting and carrying actions. Working both lower and upper back muscles will stabilise and protect the spine. A strong back therefore is required to perform daily tasks and is protective against injury. The lat pull down is the machine to use here. After the chest press it is one of the most recognised in the gym. It targets many muscles of the back, but most importantly the latissimus dorsi which is the largest back muscle. Like the chest machine it also incorporates the arms and shoulders. The second machine for your back is the seated cable row machine. It works all the muscles across your middle back and in addition uses the triceps and biceps as stabilisers.</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Arms – Strong toned arms look amazing. Beyond aesthetics however, regular arm exercises are closely linked to longevity as they strengthen your heart, improve circulation and can generally reduce the risk of heart disease. The assisted pull up (or chin up) machine is a fabulous way to work your arms and you can target different areas with different grips. A neutral (palms facing each other) and narrow grip is a highly effective way to work biceps and triceps especially for women who are still building upper body strength.</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Shoulders – The shoulders – or deltoids -are among the most important we use in daily life. Whether we are pushing, pulling or lifting things over our head, they always come in to play. Great shoulders also make us look strong and confident. The shoulder press machine improves shoulder size, strength, stability and mobility. It also extends these benefits to the tricep muscles in the arms.</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Legs – Leg exercises are excellent because not only do they make our legs look toned and beautiful they improve your overall body fitness and flexibility. Leg workouts engage the major muscle groups of the body which support healthy movement patterns daily life. The leg press machine is so popular, you practically need a reservation to get a few sets in. It is a powerful compound lower body exercise that works your quads glutes and hamstrings.</p> </li> <li dir="ltr" aria-level="1"> <p dir="ltr" role="presentation">Calves – Keeping the calves strong is extremely important because your calves propel you forward and absorb load with every step. You can use the Leg press machine to strengthen your calves by placing your toes and the balls of your feet on the lower part of the platform.</p> </li> </ol> <p dir="ltr"> </p> <p dir="ltr">Becoming strong and toned isn’t nearly as complicated and difficult as you might think. One of the biggest myths about building muscle and strength is that you have to spend long hard hours in the gym. This is just not the case, you simply need to put your 6 major muscle groups under pressure with some heavy weights once to twice a week. This type of training will increase your muscle mass, literally transform your body and set you on the path to a healthier, stronger, more youthful life.</p> <p dir="ltr"> </p> <p><strong>Lyndal Linkin, author of To Age or Not to Age, is a 56-year-old anti-aging expert who’s spent her lifetime learning about anti-aging solutions.

5 tips to stay strong without leaving home

<p><span id="docs-internal-guid-7c8f59ae-7fff-8a9d-bd7f-7102b75b70ef">Exercise is a necessity that can not only be daunting to start, but costly to invest in. As we get older, exercise can become even more crucial, with strength training helping us combat osteoporosis and sarcopenia, or the wasting of muscle, which can affect everything from our joints and bone density to metabolism and mobility.</span></p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/06/donna-aston.jpg" alt="" width="1280" height="720" /></p> <p dir="ltr"><em>The bestselling author and dietician has shared her tips for staying strong without leaving home. Image: Supplied</em></p> <p dir="ltr">But, exercise doesn’t have to break the bank and can be done without leaving home.</p> <p dir="ltr">To help you get started, nutritionist and bestselling author Donna Aston reveals her top 5 tips on how to stay strong without leaving home - no expensive gym memberships needed!</p> <p dir="ltr"><strong>1. Body weight</strong></p> <p dir="ltr">We really don’t need any fancy, expensive gym equipment to give our muscles a great workout. Your body weight will suffice and a chair can come in handy.

Resistance bands</strong></p> <p dir="ltr">Some fabric ‘booty bands’ are a small investment with great return. There are many online resistance band workout videos (<a href="https://astonrx.com/" target="_blank" rel="noopener">AstonRX.com</a>, Your Tube, etc.) with instruction on how to sculpt your body and activate specific muscle groups. They also serve as a great rehab tool for anyone with injuries. I always take a set with me when I travel. Consistency is key!</p> <p dir="ltr"><strong>3. Online &amp; Apps</strong></p> <p dir="ltr">The current world of advanced technology means we all have access to thousands of Apps and online video exercise instruction. And it’s not just high intensity workouts. You can find many form of home exercise, including yoga, Pilates and body weight classes, and from beginners through to advanced.</p> <p dir="ltr"><strong>4. Use what you have</strong></p> <p dir="ltr">If you feel you’d like to add further resistance and variety to your body weight regime, you may be surprised what you can use as weights.

Motion sickness: this might explain why some people feel sick in cars or on trains

<p>If you’re someone who suffers from motion sickness, travelling in many types of vehicles can be difficult thanks to a host of symptoms like dizziness, lightheadedness, nausea and even vomiting. But it’s not completely clear why some people can read and play games on their phone during a long drive while others spend the journey desperately trying not to be sick. Nor is it clear why some people only experience motion sickness in certain types of vehicles and not others. </p> <p>But there are two theories that might help explain what’s going on. </p> <p>The <a href="https://cdnsciencepub.com/doi/abs/10.1139/y90-044">sensory conflict theory</a> proposes that a key player in motion sickness is our balance system. Balance is not maintained by just one single sensory organ. Rather, it combines what we’re seeing and feeling with information from the balance organ in our inner ears, which helps our balance system work out exactly where we are.</p> <p>If the information from our eyes, inner ears and touch or pressure senses doesn’t match up, it can make us feel off-balance or unsteady. This is why it’s thought that motion sickness is caused by a mismatch of information from our senses – with our eyes and inner ear telling our body that we’re moving, even though we’re actually sitting stationary. This is also why the <a href="https://cdnsciencepub.com/doi/abs/10.1139/y90-044">less sensory mismatch we experience</a> in a vehicle, the less likely we are to experience motion sickness. For example, travelling in a car on a smooth, straight road will cause less sensory mismatch than travelling on a winding road with lots of potholes.</p> <p>This theory is currently considered the strongest explanation for motion sickness – though we’re still trying to understand the brain mechanisms that cause <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/cns.12468">motion sickness</a>. </p> <p>An alternate (but related) theory suggests that it’s all down to <a href="https://www.tandfonline.com/doi/abs/10.1207/s15326969eco0303_2?src=recsys">controlling posture</a>. According to this theory, motion sickness doesn’t happen just because of the mismatch of sensory information. Rather, it’s our inability to adjust our posture to reduce this mismatch of sensory information that makes us feel nauseous. While this makes sense – especially since we can’t always move around when travelling – there <a href="https://www.tandfonline.com/doi/abs/10.1207/s15326969eco0703_1">isn’t much evidence</a>to support this theory. </p> <h2>No single reason</h2> <p>Motion sickness affects people differently, and there’s no single reason why some people experience motion sickness more frequently than others. But differences in how well a person’s vision and balance systems work will affect how they may feel in different types of vehicles. Certain disorders – including migraines and inner ear diseases, such as Ménière’s disease – <a href="https://www.sciencedirect.com/science/article/pii/S1566070206002128">increase the likelihood</a> of experiencing motion sickness. <a href="https://www.sciencedirect.com/science/article/pii/S1566070206002128">Age and sex</a> may also affect likelihood of experiencing motion sickness – with some research suggesting experiences peak around nine or ten years of age, and are more common in women. However, it is uncertain as to why this may be the case.</p> <p>The <a href="https://www.sciencedirect.com/science/article/pii/S1566070206002128">type of vehicle</a> people travel in will also have some affect on the amount of motion sickness a person may experience. Broadly, any factor that increases the mismatch between each of the senses that contribute to our balance system will increase the risk of motion sickness. The longer the experience lasts and the larger the size of the movement, the worse the symptoms. For example, travelling on a small boat in a storm for more than eight hours will cause quite severe symptoms – whereas a one-hour train journey will probably have little effect, even if the track isn’t perfectly smooth.</p> <p>Many people also report experiencing motion sickness when they’re a passenger – not when they’re driving a vehicle. This is probably because drivers are (unsurprisingly) much better at anticipating the motion of a vehicle and move their bodies according to the movement of the vehicle. For example, if a car travels around a sharp bend, the driver is going to be looking ahead and anticipating the movement of the car as they turn – while a passenger is likely to react as the turn happens by leaning in the opposite direction. </p> <p>Motion sickness also isn’t limited to the “real world”, with <a href="https://dl.acm.org/doi/pdf/10.1145/2677758.2677780?casa_token=Wni6ONyXbJsAAAAA:MgFIc_qg3Kos4-rIbVZQD_FfuRhmbuGqf4N6OO1rKuQitKBPbGJ7wxDbJJNEPPq0CryffMEmmPSc">cybersickness</a> another type of motion sickness that people get from the virtual environments, often when playing video games. This likely happens because of the sensory conflict of seeing the environment move on the screen while the body remains stationary. <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0056160">Watching films in 3D</a> at the cinema can prompt motion sickness for the same reason.</p> <p>If you’re someone who suffers from motion sickness, the best thing to do the next time you’re in a vehicle is try to reduce the mismatch of sensory information. So avoid reading in the car – as this causes a mismatch between what we’re seeing and what we’re feeling – and try to instead look out the window. This may help reduce nausea as the visual information now better matches the balance information in our the inner ear. The same is true for boats and trains – focusing on the passing landscape can reduce symptoms.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7048153">Other tips</a> to reduce motion sickness include not having a heavy meal before travel, ventilating the vehicle and taking regular stops (when possible). But if these tips aren’t enough to tackle symptoms, using an <a href="https://journals.sagepub.com/doi/pdf/10.1177/014556130608500110">anti-motion sickness medication</a> may help. These reduce activity in the balance system of the brain or reduce the number of signals the brain sends to the gut, which can help to stop nausea and vomiting.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/motion-sickness-this-might-explain-why-some-people-feel-sick-in-cars-or-on-trains-178087" target="_blank" rel="noopener">The Conversation</a>. </em></p>

15 memory exercises proven to keep your brain sharp

<p><strong>Draw a map</strong></p> <p>Research shows that building a mental map is a serious brain-booster. Cab drivers in London, for example, are required to memorise 25,000 streets and 20,000 landmarks in order to qualify for a licence. But new geography skills aren’t the only perk; neurologists at the University of London found that these cabbies have significantly larger hippocampi, or regions of the brain that store and organise memories.</p> <p>Memory exercise: draw a map – of your neighbourhood, your commute, or another familiar area – completely from memory. Then, repeat this exercise each time you visit a new place or take a different route home.</p> <p><strong>Quiz yourself</strong></p> <p>Forget fancy computer games; paper and pen is the tried-and-true method for improving your memory, experts say.</p> <p>Memory exercise: try making and memorising a list of grocery items, tasks to complete, etc. Then, see how many items you can recall after one or two hours. The longer (and more complicated) the list, the tougher the workout for your brain.</p> <p><strong>Practise simple maths problems</strong></p> <p>Did you think you could bid maths farewell after graduating high school? Think again. According to experts, an addition or subtraction problem a day can keep cognitive decline away.</p> <p>Memory exercise: solve a few simple maths problems in your head each morning – no pencil, paper, or calculator allowed. To up the ante, try to walk or cook at the same time.</p> <p><strong>Test your taste buds</strong></p> <p> </p> <p>Cooking is a win-win for your brain. Both making and eating a meal activates the brain regions associated with smell, touch, sight and taste. Plus, using your senses can also improve your recall. In one study, adults who looked at a series of images were more likely to remember those with a fragrance than the ones without.</p> <p>Memory exercise: as you chew, take a moment to distinguish the taste of individual ingredients in the dish, all the way down to the faintest herbs and spices.</p> <p><strong>Tell a story</strong></p> <p>Storytelling is a great mental stimulant, helping you focus on important details, associate emotion with your memories, and recall important life events with ease later on. It has been used as a treatment for Alzheimer’s disease too.</p> <p>Memory exercise: before you go to sleep at night, replay the day’s events in your head. Try to recall the details from each moment, starting from the minute you woke up to when you climbed into bed.</p> <p><strong>Take a class</strong></p> <p>To keep your noggin in tip-top shape, it’s important to keep learning – no matter your age. Experts believe that continuing to learn throughout your life can prevent mental ageing and boost your memory.</p> <p>Memory exercise: whether it is cooking or calculus, enrol in a class that will teach you something new. Trust us, your brain will thank you.</p> <p><strong>Play a new sport</strong></p> <p>Getting your heart pumping can also keep your brain bumping. Athletic activities that stimulate your mind and body, such as yoga, golf, or tennis, have been linked to improved brain function and energy levels.</p> <p>Memory exercise: sign up to learn a sport you have never played before, and study up on the rules and procedures.</p> <p><strong>Challenge your fine-motor skills</strong></p> <p>Like learning a sport or enrolling in a new class, mastering an activity that requires considerable hand-eye coordination can keep your brain active and healthy.</p> <p>Memory exercise: pick up a new hobby that requires you to use your hands, such as knitting, painting or assembling a jigsaw puzzle. Even better, chew gum while you do it; one study found that chewing gum while completing a task could improve concentration and memory.</p> <p><strong>Memorise phone numbers</strong></p> <p>Even a short brain-training session can make a big difference for your memory. By challenging your brain with memorisation puzzles, experts believe you can protect your brain cells and strengthen the connections between them.</p> <p>Memory exercise: impress your friends by memorising their phone numbers. Dr Ashraf Al recommends dividing each 10-digit number into three sections; for example, 801 555 8372 is much easier to remember than 8015558372.</p> <p><strong>Create a mnemonic phrase</strong></p> <p>Making a mnemonic device is one foolproof way to store an important rule, fact, or to-do list in your memory bank. Some are acronyms, such as RICE, (Rest, Ice, Compression, and Elevation), a first-aid treatment for injuries. Others come in the form of sentences, like ‘spring forward, fall back’, a reminder to reset your clock twice a year.</p> <p>Memory exercise: the next time you need to memorise something in a hurry, come up with a clever acronym or sentence for it.</p> <p><strong>Learn a foreign language</strong></p> <p>Studies show that learning something new and complex over a long period of time can protect an ageing brain. Not only are listening and hearing exercises great mental stimulants, but learning a new language can also reduce your risk of cognitive decline.</p> <p>Memory exercise: enrol in a foreign language course at your local college or online. If you’re strapped for time,<span> </span><em>Rosetta Stone</em><span> </span>or<span> </span><em>Duolingo</em><span> </span>will allow you to learn at your own pace.</p> <p><strong>Increase your processing speed</strong></p> <p>Quick on your feet, or slow to the punch? If your answer is the latter, your brain might be in trouble. Learning to react and process things at a fast pace can ward off dementia, according to research published in the journal<span> </span><em>Frontiers in Aging Neuroscience</em>.</p> <p>Memory exercise: try PQRST, a five-step method for processing lengthy written information quickly. The acronym stands for: Preview or skim the material, ask Questions about the document’s main points, Reread it, Study the answers to your questions, and Test yourself.</p> <p><strong>Repeat it out loud</strong></p> <p>Saying information out loud can increase your chances of remembering it later, research says. In a study published in the journal<span> </span><em>Memory</em>, subjects who read written information out loud showed a five to 15 per cent boost in retention.</p> <p>Memory exercise: to remember something you have just done, heard, or read, repeat it out loud; doing so will nail the memory down in your mind.</p> <p><strong>Conserve your mental energy</strong></p> <p>Don’t waste valuable brainpower trying to remember where you put your keys or the time of your next doctor’s appointment. By removing unnecessary distractions, you can focus your energy on new information you actually want to remember, instead.</p> <p>Memory exercise: keep a calendar or planner, and designate a space for items you often lose.</p> <p><strong>Use visual cues</strong></p> <p>Last but certainly not least, there’s no harm in the occasional string around your finger to jog your memory.</p> <p>Memory exercise: place Post-It notes on your computer keyboard, desk, or fridge to serve as reminders throughout the day. You can wear a bracelet or put an alarm on your phone, too.</p> <p><em><span style="font-weight: 400;">Written by Brooke Nelson.

Sydney to Newcastle fast rail makes sense. Making trains locally does not

<p>Federal Opposition Leader Anthony Albanese <a href="https://anthonyalbanese.com.au/our-policies/sydney-to-hunter-fast-rail">this week announced</a> a commitment to funding high-speed rail between Sydney and Newcastle.</p> <p>At speeds of more than 250km/h, this would cut the 150-minute journey from Sydney to Newcastle to just 45 minutes. Commuting between the two cities would be a lot more feasible.</p> <p><a href="https://images.theconversation.com/files/439624/original/file-20220106-21-19utua0.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/439624/original/file-20220106-21-19utua0.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt="" /></a> <span class="caption">Proposed route for high-speed Melbourne to Brisbane rail.</span> <span class="attribution"><a href="https://www.infrastructureaustralia.gov.au/map/corridor-preservation-east-coast-high-speed-rail" class="source">Infrastructure Australia</a></span></p> <p>The Sydney-Newcastle link would be a first step in a grand plan to link the Melbourne-Sydney-Brisbane corridor by high-speed rail.</p> <p>Albanese also wants the trains to be built at home, <a href="https://anthonyalbanese.com.au/our-policies/sydney-to-hunter-fast-rail">saying</a> “we will look build as much of our fast and high-speed rail future in Australia as is possible”.</p> <p>Of course, this idea has been around for a long time. Nobody has ever got the numbers to stack up before.</p> <p>Federal infrastructure minister Paul Fletcher made the obvious but reasonable point that such a rail link would be very expensive.</p> <p>“It is $200 to $300 billion on any credible estimate,” he <a href="https://newcastleweekly.com.au/coalition-pulls-brakes-on-labors-fast-rail-plans/">said in response</a> to Labor’s announcement. “It has to be paid for, and that means higher taxes”.</p> <p>Or does it?</p> <h2>Social cost-benefit analysis</h2> <p>Traditional cost-benefit analysis is how governments tend to make decisions about big infrastructure projects like this. Figure out the costs (such as $300 billion) and then figure out the benefits. Adjust for timing differences and when money is spent and received, and then compare.</p> <p>This generates an “internal rate of return” (IRR) on the money invested. It’s what private companies do all the time. One then compares that IRR to some reference or “hurdle” rate. For a private company that might be 12% or so. For governments it is typically lower.</p> <p>An obvious question this raises is: what are the benefits?</p> <p><a href="https://images.theconversation.com/files/439623/original/file-20220106-27-vyofyv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/439623/original/file-20220106-27-vyofyv.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="" /></a> <span class="caption">An artist’s impression by Phil Belbin of the proposed VFT (Very Fast Train) in the 1980s.</span> <span class="attribution"><span class="source">Comeng</span></span></p> <p>If all one is willing to count are things such as ticket fares, the numbers will almost never stack up. But that’s far too narrow a way to think about the financial benefits.</p> <p>A Sydney-Newcastle high-speed rail link would cut down on travel times, help ease congestion in Sydney, ease housing affordability pressures in Sydney, improve property values along the corridor and in Newcastle, provide better access to education and jobs, and more.</p> <p>The point is one has to think about the social value from government investments, not just the narrow commercial value. Alex Rosenberg, Rosalind Dixon and I provided a framework for this kind of “social return accounting” in a <a href="http://research.economics.unsw.edu.au/richardholden/assets/social-return-accounting.pdf">report</a> published in 2018.</p> <h2>Newcastle might make sense, Brisbane might not</h2> <p>I haven’t done the social cost-benefit analysis for this rail link, but the social return being greater than the cost is quite plausible.</p> <p>The other thing to remember is that the return a government should require has fallen materially in recent years. The Australian government can borrow for 10 years at just 1.78%, as opposed to <a href="http://www.worldgovernmentbonds.com/bond-historical-data/australia/10-years/">well over 5%</a> before the financial crisis of 2008.</p> <p>I’m less sure about the Brisbane to Melbourne idea. The cost would be dramatically higher for obvious reasons, as well as the fact that the topography en route to Brisbane is especially challenging.</p> <p>Nobody is going to commute from Sydney to Brisbane by rail, and the air routes between the three capitals are well serviced.</p> <h2>Transport policy is not industry policy</h2> <p>The decision about building a Sydney-Newcastle rail link is, and should be kept, completely separate from where the trains are made. Transport policy shouldn’t be hijacked for industry policy.</p> <p>To be fair, Newcastle has a long and proud history of <a href="https://www.ugllimited.com/en/our-sectors/transport">manufacturing rolling stock</a>, at what was the Goninan factory at Broadmeadow – much of it for export.</p> <p>But ask yourself how sustainable that industry looks in Australia, absent massive government support. Can it stand on its own?</p> <p>It’s also true there have been some recent high-profile procurement disasters buying overseas trains.</p> <p>Sydney’s light-rail project has run massively late and over budget, with Spanish company Acciona getting an extra A$600 million due to the project being more difficult than expected.</p> <p>Then <a href="https://www.smh.com.au/national/nsw/transport-minister-expects-spanish-manufacturer-to-pay-for-cracked-trams-20211110-p597tq.html">cracks were found</a> in all 12 trams for the city’s inner-west line, putting them out of service for 18 months.</p> <p>These are terrible bungles due to the government agreeing to poorly written contracts with sophisticated counterparties. When contracts don’t specify contingencies there is the possibility of what economists call the “<a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1530-9134.2009.00236.x">hold-up problem</a>”.</p> <p>But these problems could have occurred with a local maker too.</p> <h2>The Tinbergen Rule</h2> <p>An enduring lesson from economics is the Tinbergen Rule – named after <a href="https://www.nobelprize.org/prizes/economic-sciences/1969/tinbergen/facts/">Jan Tinbergen</a>, winner of the first Nobel prize for economics.</p> <p>This rule says for each policy challenge one requires an independent policy instrument. This can be <a href="https://theconversation.com/vital-signs-evergrande-may-survive-but-for-its-executives-expect-a-fate-worse-than-debt-168930">widely applied</a>. But here the lesson is particularly clear.</p> <p>Addressing housing affordability is a good idea, and a Sydney-Newcastle link could help with that. But if Labor want a jobs policy it should develop one.</p> <p>The more TAFE places Labor has already announced is a reasonable start.</p> <p>Reviving 1970s-style industry policy – something that has almost never worked – is not a good move. Governments are lousy at picking winners. The public invariably ends up paying more for less, and the jobs are typically transient.</p> <p>But aside from this conflation of policy goals, Albanese deserves credit for being bold about the future of high-speed rail in Australia.</p> <p><span><a href="https://theconversation.com/profiles/richard-holden-118107">Richard Holden</a>, Professor of Economics, <em><a href="https://theconversation.com/institutions/unsw-1414">UNSW</a></em></span></p> <p>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
