"This can't be real": Couple's unbelievable op-shop find

An Australian man has made an epic discovery in his local op shop. Rob Klaric was browsing Lifeline's Mosman store on Sydney's north shore when he spotted two framed photos of himself and his wife, which they had lost while moving house more than 30 years ago. The photos were taken in 1988 when he and Leonie, his wife of 35 years, were backpacking across Europe. But turns out luck was on their side and they were reunited with their prized possession more than three decades later. "I'm still buzzing with this. I mean, what's the chances?" he told 2GB's Ben Fordham. "I've walked into a store and I see these pictures and I thought I was hallucinating." The photos hold special meaning for the couple, as it was taken in his mum's backyard when they went to visit her in Europe. "We backpacked across Europe, [went] to my mother's place in the north of Italy – so the photos are iconic because it's [taken] in my mother's backyard and Mum's just passed away a few years ago now." A year later, the couple got married, and the year following they had these images framed before they lost them in a move in 1933, when a removal company misplaced the boxes they were packed in. "I still tremble because I thought, 'this can't be real'." "The ironic thing is that my picture, apologies Leonie, mine was more expensive. It was $12 and hers was $8," he said. Klaric wondered if his late mother had something to do with the special find. "But look, it's got my mum, my beautiful old Italian mum, it's got her fingerprints all over it," he said. "Because those pictures were right in the middle [of the shop], on the floor, you would have never seen it unless you walked through the store. And if it was on the left or the right you wouldn't have seen it. "I think she's looking down from Heaven." Images: DailyMail

Readers response: What's a pain you can't truly explain until you've endured it?

When it comes to experiencing pain, many of us are used to hearing people say "I know how you feel" while they're empathising with your suffering. However, there are some kinds of pain - either physical or emotional - that cannot be understood until you experience them yourself. We asked our readers what pain you can't truly explain until you've endured it yourself, and the response was overwhelming. Here's what they said. Anne Hare - Shingles! Absolutely excruciating. I seriously considered topping myself until I was finally prescribed Lyrica. Took five months to recover as misdiagnosed twice so antivirals prescribed too late. Have the shot! Karen Ambrose - Childbirth. 15.5 hours of agony. Annette Maree - Pain from a dying nerve in a tooth. Royce Jowett - The worst pain is always the one you are currently experiencing, especially as you get older and forgetful. Julia Santos - Hip pain is hard to explain how it affects your whole day. Even trying to sleep is an adventure. And sneezing while your hips are inflamed is always fun. Betty Weller Edwards - Gallbladder stones. I would rather go through labor for 12 hours than have 4 hours off gallbladder pain. Sandra Morris - The loss of your child. Kevin Chapman - Chronic arthritis. The pain is 24/7, it never goes away. Danny Bennett - Divorce. Patricia White - Dislocated shoulder. Jill Harker - A couple of bulging discs in my back! Linda Charlton - Clot in the lungs, couldn't breathe thought I was having a heart attack in my 30's. Other than that, definitely childbirth. George Dworcowyi - Back spasms after a 7 hour operation on my broken spine. Maxine Cuevas - Losing two adult children at separate times. Josephine Broughton - White tail spider bite. Shelley Woolley - Ruptured ovarian cysts. Image credits: Shutterstock

"You guys can't touch me": Djokovic slams Wimbledon crowd

Novak Djokovic has launched into a staggering tirade after emerging from the Wimbledon courts victorious, after claiming the crowd was being "disrespectful" by booing him. The Serbian tennis champ accused the audience after his 6-3, 6-4, 6-2 victory over Danish player Holger Rune, calling out the behaviour during his winning speech. “To all the fans that have had respect and stayed here tonight, I thank you from the bottom of my heart and I appreciate it,” he said. “And to all those people that have chosen to disrespect the player, in this case me, have a goooood night." “Goooood night, goooood night, have a good night,” he continued. The on-court interviewer suggested that the crowd was chanting “Rooooon” and was not in fact booing, but Djokovic was determined. “I’m hoping they were just commenting on Rune and they weren’t disrespecting you,” the courtside interviewer said, as Djokovic responded, “They were, they were, they were, they were.” “I am not accepting it. No, no, no. I know they were cheering for Rune but that’s an excuse to also boo." “Listen, I have been on the tour for more than 20 years." “I know all the tricks. I focus on the respectful people that pay for the ticket, and love tennis and appreciate the players." “I have played in much more hostile environments, trust me ... you guys can’t touch me.” He then headed for the Centre Court exit to initial applause before further chants of "Ruuuuuuune" followed.

Why can’t I sleep? It could be your sheets or doona

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/chin-moi-chow-169404">Chin Moi Chow</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/cynthia-xinzhu-li-1532937">Cynthia (Xinzhu) Li</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/mark-halaki-1532934">Mark Halaki</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s winter, so many of us will be bringing out, or buying, winter bedding. But how much of a difference does your bedding make to your thermal comfort? Can a particular textile help you sleep? Is it wool, or other natural fibres, such as cotton? How about polyester? With so much choice, it’s easy to be confused. Here’s what we <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jsr.14217">found</a> when we reviewed the evidence – not just for winter, but also for the summer ahead. <h2>The importance of bedding</h2> We <a href="https://doi.org/10.1016/j.enbuild.2020.110097">rely on our bedding</a> to maintain a comfortable temperature to help us sleep. And the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378778817317681">right textiles</a> can help regulate our body temperature and <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/9783527342587.ch31">wick away moisture</a> from sweat, promoting better sleep. In the cooler months, we’re mainly concerned about a textile’s insulation properties – keeping body heat in and the cold out. As the temperature climbs, we’re less concerned about insulation and more concerned about wicking away moisture from sweat. Another factor to consider is a textile’s breathability – how well it allows air to pass through it. A breathable textile helps keep you cool, by allowing warmth from your body to escape. It also helps keep you comfortable by preventing build-up of moisture. By releasing excess heat and moisture, a breathable textile makes it feel cooler and more comfortable against the skin. <h2>Different textiles have different properties</h2> Some textiles are better than others when it comes to insulation, wicking away moisture or breathability. For instance, cotton and wool have tiny air pockets that <a href="https://nopr.niscair.res.in/bitstream/123456789/24505/1/IJFTR%2031(1)%20177-186.pdf">act as insulation</a> to provide <a href="https://www.sciencedirect.com/science/article/abs/pii/0379711281900072">warmth</a> in cold weather. Thicker fabrics with more air pockets tend to be warmer, softer and more breathable. But these factors are also affected by the type of fibre, the weave of the fabric and the manufacturing process. Cotton and wool are also breathable fabrics, meaning they help regulate temperature. <hr /> <iframe id="CqVe0" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/CqVe0/" width="100%" height="400px" frameborder="0"></iframe> <hr /> While cotton absorbs moisture (sweat) from your skin, it doesn’t wick it away efficiently. This retained moisture can make cotton feel clingy and uncomfortable, potentially leading to chills in warm weather. But wool is <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jsr.14217">highly absorbent</a> and wicks moisture effectively. In warmer weather, when we sweat, wool fibres allow for airflow and moisture transfer, promoting efficient sweat evaporation and cooling, and preventing overheating. So wool (in different thicknesses) can be a good option in both summer and winter. Linen, although breathable and having moisture-wicking properties, provides less insulation than wool and cotton due to its hollow fibres. This makes linen less effective for keeping warm in winter but is effective for keeping cool in summer. Polyester is a synthetic fibre that can be made to trap air for insulation, but it is not naturally breathable. Usually, it absorbs moisture poorly. So it can trap sweat next to the skin, causing discomfort. However, polyester can be specially treated to help control moisture from sweat. <h2>Which sheets help you sleep?</h2> As part of our review, we couldn’t find any studies that directly compared sheets made from different textiles (for instance, regular cotton and flannelette) and their impact on sleep when it’s cold. However, linen sheets are particularly effective in warmer conditions. In one study, conducted at 29°C and high humidity, linen sheets <a href="https://openurl.ebsco.com/EPDB%3Agcd%3A10%3A26460954/detailv2?sid=ebsco%3Aplink%3Ascholar&id=ebsco%3Agcd%3A87732897&crl=c">promoted</a> less wakefulness and fewer stages of light sleep than cotton sheets. <h2>How about doonas?</h2> If you don’t heat your bedroom at night in winter, a goose down doona (one made from fine, goose feathers) might be an option. These promoted the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378778818321728">longest, deep-sleep</a>, followed by duck down, then cotton when sleeping at 11°C. This may be because down offers better insulation (by trapping more air) than cotton. Down also has lower thermal conductivity than cotton, meaning it’s better at keeping warmth in. Choosing between a wool or polyester doona? In a wool-industry funded <a href="https://www.tandfonline.com/doi/full/10.2147/NSS.S100271">study</a> two of us (Chow and Halaki) co-authored, there wasn’t much difference. The study in young adults found no significant difference on sleep at 17°C or 22°C. <h2>So how do I choose?</h2> The choice of bedding is highly individual. What feels comfortable to one person is not the same for the next. That’s because of variations in body size and metabolic rate, local climate, bedroom temperature and building insulation. These can also affect sleep. This variability, and a wide range of study designs, also makes it hard to compare different studies about the impact of different textiles on sleep. So you might need to experiment with different textiles to discover what works for you. <hr /> Many factors can affect your sleep, not just your bedding. So if you’re having trouble sleeping, you can find more information from the <a href="https://www.sleephealthfoundation.org.au/">Sleep Health Foundation</a>.

Cost of living: if you can’t afford as much fresh produce, are canned veggies or frozen fruit just as good?

<a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> The cost of living crisis is affecting how we spend our money. For many people, this means tightening the budget on the weekly supermarket shop. One victim may be fresh fruit and vegetables. Data from the <a href="https://www.abs.gov.au/media-centre/media-releases/australians-consuming-fewer-vegetables-fruit-and-less-milk#:%7E:text=Paul%20Atyeo%2C%20ABS%20health%20statistics,278%20to%20267%20to%20grams.%E2%80%9D">Australian Bureau of Statistics</a> (ABS) suggests Australians were consuming fewer fruit and vegetables in 2022–23 than the year before. The cost of living is likely compounding a problem that exists already – on the whole, Australians don’t eat enough fruit and vegetables. <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">Australian dietary guidelines</a> recommend people aged nine and older should consume <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">two</a> serves of fruit and <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/vegetables-and-legumes-beans">five</a> serves of vegetables each day for optimal health. But in 2022 the <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/dietary-behaviour/latest-release">ABS reported</a> only 4% of Australians met the recommendations for both fruit and vegetable consumption. Fruit and vegetables are crucial for a healthy, balanced diet, providing a range of <a href="https://theconversation.com/were-told-to-eat-a-rainbow-of-fruit-and-vegetables-heres-what-each-colour-does-in-our-body-191337">vitamins</a> and minerals as well as fibre. If you can’t afford as much fresh produce at the moment, there are other ways to ensure you still get the benefits of these food groups. You might even be able to increase your intake of fruit and vegetables. <h2>Frozen</h2> Fresh produce is often touted as being the most nutritious (think of the old adage “fresh is best”). But this is not necessarily true. Nutrients can decline in transit from the paddock to your kitchen, and while the produce is stored in your fridge. Frozen vegetables may actually be higher in some nutrients such as <a href="https://pubmed.ncbi.nlm.nih.gov/25526594/">vitamin C and E</a> as they are snap frozen very close to the time of harvest. Variations in transport and storage can affect this slightly. <a href="https://pubs.acs.org/doi/10.1021/jf504890k">Minerals</a> such as calcium, iron and magnesium stay at similar levels in frozen produce compared to fresh. Another advantage to frozen vegetables and fruit is the potential to reduce food waste, as you can use only what you need at the time. As well as buying frozen fruit and vegetables from the supermarket, you can freeze produce yourself at home if you have an oversupply from the garden, or when produce may be cheaper. A <a href="https://www.growveg.com.au/guides/freezing-vegetables-and-herbs-the-garden-foodie-version/">quick blanching</a> prior to freezing can improve the safety and quality of the produce. This is when food is briefly submerged in boiling water or steamed for a short time. Frozen vegetables won’t be suitable for salads but can be eaten roasted or steamed and used for soups, stews, casseroles, curries, pies and quiches. Frozen fruits can be added to breakfast dishes (with cereal or youghurt) or used in cooking for fruit pies and cakes, for example. <h2>Canned</h2> Canned vegetables and fruit similarly often offer a cheaper alternative to fresh produce. They’re also very convenient to have on hand. The <a href="https://nchfp.uga.edu/how/can#gsc.tab=0">canning process</a> is the preservation technique, so there’s no need to add any additional preservatives, including salt. Due to the cooking process, levels of heat-sensitive nutrients <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/jsfa.2825">such as vitamin C</a> will decline a little compared to fresh produce. When you’re using canned vegetables in a hot dish, you can add them later in the cooking process to reduce the amount of nutrient loss. To minimise waste, you can freeze the portion you don’t need. <h2>Fermented</h2> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6723656/">Fermentation</a> has recently come into fashion, but it’s actually one of the oldest food processing and preservation techniques. Fermentation largely retains the vitamins and minerals in fresh vegetables. But fermentation may also enhance the food’s nutritional profile by creating new nutrients and allowing existing ones to be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9352655/">absorbed more easily</a>. Further, fermented foods contain probiotics, which are beneficial for our <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10051273/">gut microbiome</a>. <h2>5 other tips to get your fresh fix</h2> Although alternatives to fresh such as canned or frozen fruit and vegetables are good substitutes, if you’re looking to get more fresh produce into your diet on a tight budget, here are some things you can do. 1. Buy in season Based on supply and demand principles, buying local seasonal vegetables and fruit will always be cheaper than those that are imported out of season from other countries. 2. Don’t shun the ugly fruit and vegetables Most supermarkets now sell “ugly” fruit and vegetables, that are not physically perfect in some way. This does not affect the levels of nutrients in them at all, or their taste. 3. Reduce waste On average, an Australian household throws out <a href="https://www.ozharvest.org/food-waste-facts/">A$2,000–$2,500</a> worth of food every year. Fruit, vegetables and bagged salad are the <a href="https://www.ozharvest.org/food-waste-facts/">three of the top five foods</a> thrown out in our homes. So properly managing fresh produce could help you save money (and benefit <a href="https://endfoodwaste.com.au/why-end-food-waste/">the environment</a>). To minimise waste, plan your meals and shopping ahead of time. And if you don’t think you’re going to get to eat the fruit and vegetables you have before they go off, freeze them. 4. Swap and share There are many websites and apps which offer the opportunity to swap or even pick up free fresh produce if people have more than they need. Some <a href="https://www.charlessturt.sa.gov.au/environment/sustainable-lifestyles/community-fruit-and-vege-swaps">local councils are also encouraging</a> swaps on their websites, so dig around and see what you can find in your local area. 5. Gardening Regardless of how small your garden is you can always <a href="https://www.gardeningaustraliamag.com.au/best-vegies-grow-pots/">plant produce in pots</a>. Herbs, rocket, cherry tomatoes, chillies and strawberries all grow well. In the long run, these will offset some of your cost on fresh produce. Plus, when you have put the effort in to grow your own produce, <a href="https://mdpi-res.com/sustainability/sustainability-07-02695/article_deploy/sustainability-07-02695.pdf?version=1425549154">you are less likely to waste it</a>.<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/229724/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, Program Director of Nutrition and Food Sciences, Accredited Practising Dietitian, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

I can’t afford olive oil. What else can I use?

<a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> If you buy your olive oil in bulk, you’ve likely been in for a shock in recent weeks. Major supermarkets have been selling olive oil for up to A$65 for a four-litre tin, and up to $26 for a 750 millilitre bottle. We’ve been hearing about the health benefits of olive oil for years. And many of us are adding it to salads, or baking and frying with it. But during a cost-of-living crisis, these high prices can put olive oil out of reach. Let’s take a look at why olive oil is in demand, why it’s so expensive right now, and what to do until prices come down. <h2>Remind me, why is olive oil so good for you?</h2> Including olive oil in your diet can reduce your risk of developing type 2 diabetes and improve heart health through more favourable <a href="https://www.mdpi.com/2072-6643/12/6/1548">blood pressure</a>, <a href="https://www.mdpi.com/2072-6643/7/9/5356">inflammation</a> and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0939475319302662">cholesterol levels</a>. This is largely because olive oil is high in <a href="https://www.mdpi.com/2072-6643/4/12/1989">monounsaturated fatty acids</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8300823/">polyphenols</a> (antioxidants). Some researchers have suggested you can get these benefits from consuming up to <a href="https://www.frontiersin.org/articles/10.3389/fnut.2022.1041203/full">20 grams a day</a>. That’s equivalent to about five teaspoons of olive oil. <h2>Why is olive oil so expensive right now?</h2> A European heatwave and drought have <a href="https://www.abc.net.au/news/rural/2024-04-27/olive-oil-alternatives-what-you-can-use-in-cooking/103761718">limited</a> Spanish and Italian producers’ ability to supply olive oil to international markets, including Australia. This has been coupled with an unusually cold and short growing season for Australian <a href="https://www.abc.net.au/news/rural/2023-08-02/record-olive-oil-price-set-to-increase-again/102675452">olive oil suppliers</a>. The lower-than-usual production and supply of olive oil, together with heightened demand from shoppers, means prices have gone up. <h2>How can I make my olive oil go further?</h2> Many households buy olive oil in large quantities because it is cheaper per litre. So, if you have some still in stock, you can make it go further by: <ul> <li> storing it correctly – make sure the lid is on tightly and it’s kept in a cool, dark place, such as a pantry or cabinet. If stored this way, olive oil can typically last <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6218649/">12–18 months</a> </li> <li> using a spray – sprays distribute oil more evenly than pourers, using less olive oil overall. You could buy a spray bottle to fill from a large tin, as needed </li> <li> straining or freezing it – if you have leftover olive oil after frying, strain it and reuse it for other fried dishes. You could also freeze this used oil in an airtight container, then thaw and fry with it later, without affecting the oil’s <a href="https://link.springer.com/article/10.1007/s00217-022-04078-9">taste and other characteristics</a>. But for dressings, only use fresh oil. </li> </ul> <h2>I’ve run out of olive oil. What else can I use?</h2> Here are some healthy and cheaper alternatives to olive oil: <ul> <li> canola oil is a good alternative for frying. It’s relatively <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/canola-oil">low</a> in saturated fat so is generally considered healthy. Like olive oil, it is high in <a href="https://pubmed.ncbi.nlm.nih.gov/23731447/">healthy monounsaturated fats</a>. Cost? Up to $6 for a 750mL bottle (home brand is about half the price) </li> <li> sunflower oil is a great alternative to use on salads or for frying. It has a mild flavour that does not overwhelm other ingredients. Some <a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/conjugated-linoleic-acid-versus-higholeic-acid-sunflower-oil-effects-on-energy-metabolism-glucose-tolerance-blood-lipids-appetite-and-body-composition-in-regularly-exercising-individuals/6C035B5C6E9FD7C9D6D7F806ADA56983">studies</a> suggest using sunflower oil may help reduce your risk of heart disease by lowering LDL (bad) cholesterol and raising HDL (good) cholesterol. Cost? Up to $6.50 for a 750mL bottle (again, home brand is about half the price) </li> <li> sesame oil has a nutty flavour. It’s good for Asian dressings, and frying. Light sesame oil is typically used as a neutral cooking oil, while the toasted type is used to flavour sauces. Sesame oil is <a href="https://onlinelibrary.wiley.com/doi/10.1002/ptr.6428">high in</a> antioxidants and has some anti-inflammatory properties. Sesame oil is generally sold in smaller bottles than canola or sunflower oil. Cost? Up to $5 for a 150mL bottle. </li> </ul> <h2>How can I use less oil, generally?</h2> Using less oil in your cooking could keep your meals healthy. Here are some alternatives and cooking techniques: <ul> <li> use alternatives for baking – unless you are making an olive oil cake, if your recipe calls for a large quantity of oil, try using an alternative such as apple sauce, Greek yoghurt or mashed banana </li> <li> use non-stick cookware – using high-quality, non-stick pots and pans reduces the need for oil when cooking, or means you don’t need oil at all </li> <li> steam instead – steam vegetables, fish and poultry to retain nutrients and moisture without adding oil </li> <li> bake or roast – potatoes, vegetables or chicken can be baked or roasted rather than fried. You can still achieve crispy textures without needing excessive oil </li> <li> grill – the natural fats in meat and vegetables can help keep ingredients moist, without using oil </li> <li> use stock – instead of sautéing vegetables in oil, try using vegetable broth or stock to add flavour </li> <li> try vinegar or citrus – use vinegar or citrus juice (such as lemon or lime) to add flavour to salads, marinades and sauces without relying on oil </li> <li> use natural moisture – use the natural moisture in ingredients such as tomatoes, onions and mushrooms to cook dishes without adding extra oil. They release moisture as they cook, helping to prevent sticking.<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/228788/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Accredited Practising Dietitian and Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> At this time of year many of us resolve to prioritise our health. So it is no surprise there’s a <a href="https://digiday.com/marketing/health-food-brands-ramp-up-marketing-efforts-around-consumers-new-years-resolutions/">roaring trade</a> of products purporting to guarantee you live longer, be healthier and look more youthful. While an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4822264/">estimated</a> 25% of longevity is determined by our genes, the rest is determined by what we do, day to day. There are no quick fixes or short cuts to living longer and healthier lives, but the science is clear on the key principles. Here are five things you can do to extend your lifespan and improve your health. <h2>1. Eat a predominantly plant-based diet</h2> What you eat has a huge impact on your health. The evidence overwhelmingly <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8210981/#:%7E:text=According%20to%20an%20expansive%20review,13%20Given%20that%20so%20many">shows</a> eating a diet high in plant-based foods is associated with health and longevity. If you eat more plant-based foods and less meat, processed foods, sugar and salt, you reduce your risk of a range of illnesses that shorten our lives, including heart disease and cancer. Plant-based foods <a href="https://www.nature.com/articles/s41398-019-0552-0">are rich</a> in nutrients, phytochemicals, antioxidants and fibre. They’re also anti-inflammatory. All of this protects against damage to our cells as we age, which helps prevent disease. No particular diet is right for everyone but one of the most studied and <a href="https://www.hsph.harvard.edu/nutritionsource/healthy-weight/diet-reviews/mediterranean-diet/#:%7E:text=%5B6%5D%20Those%20who%20had%20the,who%20had%20the%20lowest%20adherence.">healthiest</a> is the <a href="https://www.eatingwell.com/article/291120/mediterranean-diet-for-beginners-everything-you-need-to-get-started/">Mediterranean diet</a>. It’s based on the eating patterns of people who live in countries around the Mediterranean Sea and emphases vegetables, fruits, wholegrains, legumes, nuts and seeds, fish and seafood, and olive oil. <h2>2. Aim for a healthy weight</h2> Another important way you can be healthier is to try and achieve a healthy weight, as obesity <a href="https://www.healthline.com/health/obesity/how-obesity-affects-body">increases the risk</a> of a number of health problems that shorten our lives. Obesity puts strain on all of our body systems and has a whole myriad of physiological effects including causing inflammation and hormonal disturbances. These <a href="https://www.ncbi.nlm.nih.gov/books/NBK572076/">increase your chances</a> of a number of diseases, including heart disease, stroke, high blood pressure, diabetes and a number of cancers. In addition to affecting us physically, obesity is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6052856/">associated with</a> poorer psychological health. It’s linked to depression, low self-esteem and stress. One of the biggest challenges we face in the developed world is that we live in an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6817492/">environment</a> that promotes obesity. The ubiquitous marketing and the easy availability of high-calorie foods our bodies are hard-wired to crave mean it’s easy to consume too many calories. <h2>3. Exercise regularly</h2> We all know that exercise is good for us – the <a href="https://www.insurancebusinessmag.com/au/news/breaking-news/hcf-reveals-australias-most-popular-new-years-resolutions-for-2023-431665.aspx">most common resolution</a> we make this time of year is to do more exercise and to get fitter. Regular exercise <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">protects</a> against chronic illness, lowers your stress and improves your mental health. While one of the ways exercising helps you is by supporting you to control your weight and lowering your body fat levels, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1402378/#:%7E:text=For%20instance%2C%20routine%20physical%20activity,HDL%5D%20cholesterol%20levels%20and%20decreased">effects</a> are broader and include improving your glucose (blood sugar) use, lowering your blood pressure, reducing inflammation and improving blood flow and heart function. While it’s easy to get caught up in all of the hype about different exercise strategies, the evidence <a href="https://www.medicalnewstoday.com/articles/320760">suggests</a> that any way you can include physical activity in your day has health benefits. You don’t have to run marathons or go to the gym for hours every day. Build movement into your day in any way that you can and do things that you enjoy. <h2>4. Don’t smoke</h2> If you want to be healthier and live longer then don’t smoke or vape. Smoking cigarettes affects almost every organ in the body and is associated with both a shorter and lower quality of life. There is no safe level of smoking – every cigarette increases your <a href="https://theconthatkills.org.au/?utm_source=googlesearch&utm_medium=search&utm_campaign=theconthatkills23&utm_content=RSA&gclid=Cj0KCQjwqP2pBhDMARIsAJQ0Czrlep6EQHC-8_9xUhpz0h9v2ZglMF-6-k7_65awq8FxVaIL5HRoivwaAqJwEALw_wcB&gclsrc=aw.ds">chances of developing</a> a range of cancers, heart disease and diabetes. Even if you have been smoking for years, by giving up smoking at any age you can experience <a href="https://www.cdc.gov/tobacco/quit_smoking/how_to_quit/benefits/index.htm">health benefits</a> almost immediately, and you can reverse many of the harmful effects of smoking. If you’re thinking of switching to vapes as a healthy long term option, <a href="https://theconversation.com/can-vaping-help-people-quit-smoking-its-unlikely-204812">think again</a>. The long term health effects of vaping are not fully understood and they come with their own <a href="https://theconversation.com/no-vapes-arent-95-less-harmful-than-cigarettes-heres-how-this-decade-old-myth-took-off-203039">health risks</a>. <h2>5. Prioritise social connection</h2> When we talk about living healthier and longer, we tend to focus on what we do to our physical bodies. But one of the most important discoveries over the past decade has been the recognition of the importance of spiritual and psychological health. People who are lonely and socially isolated have a much higher risk of dying early and are <a href="https://healthnews.com/longevity/healthspan/social-connection-and-longevity/#:%7E:text=One%20of%20the%20biggest%20benefits,the%20following%20factors%20and%20influences.">more likely</a> to suffer from heart disease, stroke, dementia as well as anxiety and depression. Although we don’t fully understand the mechanisms, it’s likely due to both behavioural and biological factors. While people who are more socially connected are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150158/">more likely</a> to engage in healthy behaviours, there also seems to be a more direct physiological effect of loneliness on the body. So if you want to be healthier and live longer, build and maintain your connections to others.<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/214580/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I can't go for that": Hall and Oates in bitter legal battle

In a turn of events to rival any classic Hall & Oates song about heartbreak, betrayal and possibly a saxophone solo, the iconic musical duo has found themselves embroiled in a legal battle that might just be their most melodramatic performance yet. Daryl Hall, the soulful half of the duo, has accused longtime partner John Oates of committing the "ultimate partnership betrayal". Forget "Maneater", this is more like "Share Eater". In a court declaration that reads like the lyrics of a soulful ballad, Hall lamented the deterioration of his relationship with Oates, and trust us, it's not your typical "I can't go for that (no can do)" situation. The duo's joint venture, including trademarks, personal name and likeness rights, record royalty income and even the sacred social media assets, are now centre stage for a legal showdown. It's not quite the Hall & Oates Reunion Tour we were all hoping for. It appears Oates is planning to sell his share of Whole Oats Enterprises LLP without Hall's permission (cue dramatic music) – and Hall is not taking this lying down; he's filed a lawsuit to keep the transaction on pause, turning their dispute into a legal chart-topper. A judge has issued a temporary restraining order, effectively hitting the pause button on Oates' plan to part ways with Whole Oats Enterprises, with lawyers no doubt drafting lyrics for the inevitable courtroom musical as we speak. Oates, not one to let the accusations slide, fired back in his court filing, expressing disappointment in Hall's "inflammatory, outlandish, and inaccurate statements". He claims he's been trying to enhance their business partnership, but it seems like Hall might not be feeling the groove. The legal documents reveal that Hall is deeply troubled by the deterioration of their relationship, and who can blame him? It's not every day your musical partner decides to sell the band without even a courtesy call. Amid accusations of confidentiality breaches and timing that could rival the best plot twists, this court drama has all the elements of a hit '80s ballad. Will the duo find a way to harmonise once more, or is this the end of the road for Hall & Oates? We'll have to wait for the next verse in this legal serenade. In the meantime, keep those records spinning and maybe throw in some tissues for the emotional rollercoaster. It's a private affair gone public, and the fans are left wondering, "Did I miss the memo about this 'Global Divorce' album?" Image: Instagram

What’s insomnia like for most people who can’t sleep? You’d never know from the movies

<a href="https://theconversation.com/profiles/aaron-schokman-1463327">Aaron Schokman</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/nick-glozier-94435">Nick Glozier</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Hollywood appears fascinated by sleep’s impact on the mind and body. Blockbuster movies featuring someone living with insomnia include <a href="https://www.imdb.com/title/tt0108160/">Sleepless in Seattle</a> (1993), <a href="https://www.imdb.com/title/tt0137523/">Fight Club</a> (1999) and <a href="https://www.imdb.com/title/tt0278504/?ref_=fn_al_tt_1">Insomnia</a> (2002). But how well do these and other portrayals compare with what it’s really like to live with insomnia? As we’ll see, most movies tend to either minimise or exaggerate symptoms. Insomnia is rarely depicted as a treatable illness. And these portrayals have implications for the estimated <a href="https://www.sleep.theclinics.com/article/S1556-407X(22)00022-4/fulltext">one in three</a> of us with at least one insomnia symptom. <h2>Back in the real world</h2> Insomnia is a common <a href="https://doi.org/10.1378/chest.14-0970">sleep disorder</a> where a person struggles to fall asleep, stay asleep, or wakes up too early – despite having adequate opportunity for sleep. <a href="https://doi.org/10.1111/j.1753-6405.2012.00845.x">Around 5%</a> of adults experience significant insomnia to the degree that it causes distress or impairs daily life. It’s a common misconception that insomnia is only a night-time issue. <a href="https://www.healthdirect.gov.au/insomnia">Insomnia</a> can impact your ability to stay awake and alert during the day. It can also affect your <a href="https://theconversation.com/explainer-whats-the-link-between-insomnia-and-mental-illness-49597">mental health</a>. At work, you might be more prone to accidents, more forgetful, or make poorer decisions. At home, you might be irritable or short with your friends and family. So what is it like living with insomnia? Apart from the effects of poor sleep quality, many people experience <a href="https://doi.org/10.1016/j.smrv.2021.101583">anxiety or dread</a> about the night ahead from the moment they wake up. From early in the day, people plan how they can improve their sleep that night. <a href="https://doi.org/10.1016/j.smrv.2016.01.003">A review</a> found people living with insomnia felt their sleep concerns were often trivialised or misunderstood by health-care professionals, and stigmatised by others. <h2>Movies can minimise symptoms …</h2> Nicholas Galitzine’s character in the recent romcom <a href="https://www.imdb.com/title/tt10172266/?ref_=fn_al_tt_1">Red, White and Royal Blue</a> (2023) has insomnia. We’re briefly told he struggles to fall asleep at night. However, we never see any meaningful impact on his life or depiction of the difficulty living with insomnia entails. That said, minimising the impact of insomnia can have benefits. It shows insomnia is an invisible illness, doesn’t have obvious visual symptoms and anyone can have it. But this can perpetuate the expectation someone with insomnia should be able to function unencumbered. Or it can fuel the misconception having insomnia may be beneficial, as in <a href="https://www.imdb.com/title/tt0050543/?ref_=fn_al_tt_1">Insomnia Is Good for You</a> (1957). <h2>… or exaggerate symptoms</h2> But most Hollywood portrayals of insomnia tend to depict the most extreme cases. These usually feature insomnia as a symptom of another condition rather than a disorder itself, as is commonly experienced. These movies tend to be psychological thrillers. Here, insomnia is often used as an enigma to keep the audience guessing about which events are real or figments of a character’s imagination. Take <a href="https://www.imdb.com/title/tt0361862/?ref_=fn_al_tt_1">The Machinist</a> (2004), for example. The main character is emaciated, ostracised and plagued by paranoia, hallucinations and delusions. It’s only towards the end of the movie we learn his insomnia may be the result of a <a href="https://doi.org/10.9740/mhc.n101819">psychiatric disorder</a>, such as post-traumatic stress disorder. <figure><iframe src="https://www.youtube.com/embed/-R4rQMImHwE?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>In The Machinist, the main character has paranoia, hallucinations and delusions.</figcaption></figure> Hollywood’s focus on extreme cases of insomnia is a recurring pattern (for instance, <a href="https://www.imdb.com/title/tt0137523/">Fight Club</a> 1999, <a href="https://www.imdb.com/title/tt0434165/?ref_=fn_al_tt_3">Lucid</a> 2005). It’s understandable why Hollywood latches onto these extreme portrayals – to entertain us. Yet these portrayals of insomnia as something more severe or threatening, like psychosis, can increase anxiety or stigma among people living with insomnia. While it’s true other medical conditions including <a href="https://theconversation.com/explainer-whats-the-link-between-insomnia-and-mental-illness-49597">mental illnesses</a> can lead to insomnia, insomnia often exists on its own. Insomnia is often <a href="https://theconversation.com/explainer-what-is-insomnia-and-what-can-you-do-about-it-36365">caused by</a> more mundane things like too much stress, lifestyle and habits, or longer daylight hours at higher latitudes (such as in <a href="https://www.imdb.com/title/tt0278504/?ref_=fn_al_tt_1">Insomnia</a>, 2002). Something these exaggerated portrayals do well is highlight the impact sleep deprivation can have on safety, albeit extremely dramatised. Regardless of profession, <a href="https://doi.org/10.1037/xge0000717">not getting enough sleep</a> at night can substantially impact cognitive function, increasing the chance of making a mistake. <figure><iframe src="https://www.youtube.com/embed/emIHzg4VH8A?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>In Insomnia, one character has insomnia because of extended daylight hours.</figcaption></figure> <h2>Movies rarely depict treatment</h2> It is rare to see insomnia depicted as a health condition requiring medical care. Very few characters struggling with insomnia seek or receive help for it. An exception is the narrator in <a href="https://www.imdb.com/title/tt0137523/">Fight Club</a> (1999). But he has to pretend to have other illnesses to receive therapy, again suggesting insomnia is not a legitimate condition. <figure><iframe src="https://www.youtube.com/embed/BdJKm16Co6M?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>The narrator in Fight Club pretends to have other illnesses to receive therapy for insomnia.</figcaption></figure> <h2>Why does accurate representation matter?</h2> Many people only learn about the symptoms and impact of sleep disorders through pop culture and film. These portrayals can affect how others think about these disorders and can impact how people living with these disorders think about themselves. Uniform and stereotypical portrayals of insomnia can also impact people’s <a href="https://doi.org/10.1080/15402002.2011.620671">likelihood of seeking help</a>. Most of these films show young or middle-aged men experiencing insomnia. Yet women are <a href="https://doi.org/10.1093/sleep/29.1.85">more likely</a> to have insomnia than men. Insomnia is also <a href="https://doi.org/10.1016/j.jsmc.2022.03.003">more common</a> in older adults, people with a lower socioeconomic background and those living alone. People at higher risk of developing insomnia might not recognise their risk or symptoms if their experience doesn’t match what they’ve seen. <h2>We can do better</h2> While the reality of living with insomnia may not be particularly cinematic, filmmakers can surely do better than using it as a convenient plot point. There are a number of main characters living with different health conditions across pop culture. For instance, the movie <a href="https://www.imdb.com/title/tt4034228/">Manchester by the Sea</a> (2016) features someone with <a href="https://www.rcpsych.ac.uk/news-and-features/blogs/detail/cultural-blog/2017/07/08/manchester-by-the-sea">prolonged grief disorder</a> and the TV series <a href="https://www.imdb.com/title/tt6315640/?ref_=nv_sr_srsg_0_tt_8_nm_0_q_Atypical">Atypical</a> (2017-2021) features someone’s experience living with autism. But if you’re looking for an accurate portrayal of insomnia, Hollywood still has some way to go. It’s about time insomnia is depicted in a way that accurately reflects people’s experiences.<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/211823/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/aaron-schokman-1463327">Aaron Schokman</a>, PhD Candidate, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/nick-glozier-94435">Nick Glozier</a>, Professor of Psychological Medicine, BMRI & Disciplne of Psychiatry, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"You can't forgive that": Teen arrested after felling of iconic 200-year-old tree

A 16-year-old boy has been arrested in northern England after what police describe as the "deliberate" felling of the iconic Sycamore Gap tree. The tree had stood next to the UNESCO World Heritage Site, Hadrian's Wall for nearly 200 years before it was tragically vandalised. Both locals and tourists have frequently stopped to capture a photo and appreciate the stunning tree ever since it gained fame for its appearance in Kevin Costner's 1991 film, Robin Hood: Prince Of Thieves. Now, photographs from the scene on early Thursday showed that the tree had been cut off near the base of its trunk, and the locals are fuming. "The tree is a world-renowned landmark and the vandalism has caused understandable shock and anger throughout the local community and beyond," Northumbria Police said in a statement. "This is an incredibly sad day," they added. "The tree was iconic to the North East and enjoyed by so many who live in or who have visited this region." Alison Hawkins, was the first person to spot the damage while she was walking on the Hadrian's Wall path. "It was a proper shock. It's basically the iconic picture that everyone wants to see," she said. "You can forgive nature doing it but you can't forgive that." The Northumberland National Park authority have asked the public not to visit the iconic tree, which was voted as English Tree of the Year in 2016. Police report that the teen has since been arrested on suspicion of causing criminal damage, and has been assisting officers with their inquiries. Images: Getty

The body mass index can’t tell us if we’re healthy. Here’s what we should use instead

<a href="https://theconversation.com/profiles/rachael-jefferson-buchanan-297850">Rachael Jefferson-Buchanan</a>, <a href="https://theconversation.com/institutions/charles-sturt-university-849">Charles Sturt University</a> We’ve known for some time the <a href="https://theconversation.com/using-bmi-to-measure-your-health-is-nonsense-heres-why-180412">body mass index (BMI) is an inaccurate measuring stick</a> for assessing someone’s weight and associated health. But it continues to be the go-to tool for medical doctors, population researchers and personal trainers. Why is such an imperfect tool still being used, and what should we use instead? <h2>First, what is BMI?</h2> BMI is an internationally recognised screening method for sorting people into one of four weight categories: underweight (BMI less than 18.5), normal weight (18.5 to 24.9), overweight (25.0 to 29.9) or obese (30 or greater). It’s a value <a href="https://www.cdc.gov/healthyweight/assessing/bmi/index.html">calculated</a> by a measure of someone’s mass (weight) divided by the square of their height. <h2>Who invented BMI?</h2> Belgian mathematician <a href="https://www.britannica.com/biography/Adolphe-Quetelet">Lambert Adolphe Jacques Quetelet</a> (1796-1874) devised the BMI in 1832, as a mathematical model to chart the average Western European man’s <a href="https://pubmed.ncbi.nlm.nih.gov/17890752/">physical characteristics</a>. It was initially called the <a href="https://www.msdmanuals.com/en-au/professional/multimedia/clinical-calculator/body-mass-index-quetelets-index">Quetelet Index</a> and was never meant to be used as a medical assessment tool. The Quetelex Index was renamed the “body mass index” in 1972. <h2>What’s wrong with the BMI?</h2> Using a mathematical formula to give a full picture of someone’s health is just not possible. The BMI <a href="https://www.cdc.gov/healthyweight/assessing/bmi/adult_bmi/index.html">does not measure excess body fat</a>, it just measures “excess” weight. It does not distinguish between excess body fat or bone mass or musculature, and does not interpret the distribution of fat (which is a <a href="https://www.health.harvard.edu/staying-healthy/abdominal-fat-and-what-to-do-about-it">predictor</a> of health, including type 2 diabetes, metabolic disorders, and heart disease). It also cannot tell the difference between social variables such as sex, age, and ethnicity. Given Quetelet’s formula used only Western European men, the findings are not appropriate for many other groups, including non-European ethnicities, post-menopausal women and pregnant women. The medical profession’s <a href="https://pubmed.ncbi.nlm.nih.gov/37432007/">overreliance on BMI</a> may be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2930234/">harming patients’ health</a> as it ignores much of what makes us healthy and focuses only on mass. <h2>What should we use instead?</h2> Rather than seeing BMI as the primary diagnostic test for determining a person’s health, it should be used in conjunction with other measures and considerations. Since researchers know belly fat around our vital organs carries the most <a href="https://www.bmj.com/content/370/bmj.m3324">health risk</a>, <a href="https://www.hsph.harvard.edu/obesity-prevention-source/obesity-definition/how-to-measure-body-fatness/">waist circumference</a>, waist-to-hip ratio or waist-to-height ratio offer more accurate measurements of health. Waist circumference: is an effective measure of fat distribution, particularly for athletes who carry less fat and more muscle. It’s most useful as a predictor of health when <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7027970/">combined with the BMI</a>. Waist circumference should be less than 94cm for men and 80cm for women for <a href="https://www.heartfoundation.org.au/bundles/your-heart/waist-measurement">optimal health</a>, as measured from halfway between the bottom of your ribs and your hip bones. Waist-to-hip ratio: calculates the proportion of your body fat and how much is stored on your waist, hips, and buttocks. It’s the waist measurement divided by hip measurement and according to the World Health Organisation it should be <a href="https://apps.who.int/iris/bitstream/handle/10665/44583/9789241501491_eng.pdf;jsessionid=A119D165CFFF5E7B5BDBD51D9DD25684?sequence=1">0.85 or less for women, and 0.9 or less in men</a> to reduce health risks. It’s especially beneficial in predicting health outcomes in <a href="https://link.springer.com/article/10.1007/s40200-021-00882-4">older people</a>, as the ageing process alters the body proportions on which BMI is founded. This is because fat mass increases and muscle mass decreases with age. Waist-to-height ratio: is height divided by waist circumference, and it’s <a href="https://www.nice.org.uk/news/article/keep-the-size-of-your-waist-to-less-than-half-of-your-height-updated-nice-draft-guideline-recommends">recommended</a> a person’s waist circumference be kept at less than half their height. Some studies have found this measure is <a href="https://bmjopen.bmj.com/content/6/3/e010159">most strongly correlated</a> with health predictions. Body composition and body fat percentage can also be calculated through <a href="https://www.youtube.com/watch?v=a1A9m0wO17g">skinfold measurement tests</a>, by assessing specific locations on the body (such as the abdomen, triceps or quadriceps) with skin callipers.

"I can't wake Mummy up": Olympian dies at 43

A former Olympic swimmer has passed away suddenly at the age of 43 while on a trip with her family. Helen Smart, a British swimming champion who competed at the 2000 Sydney Olympics, was found unresponsive by her four-year-old daughter Heidi when she tried to climb into bed with her parents. Heidi then woke up her father Craig Smart, saying, "Daddy, I can't wake Mummy up," before Craig discovered his wife lying next to him dead. Smart's mother confirmed the news of her passing, telling the <a href="https://www.dailymail.co.uk/news/article-12413199/Ex-Olympic-swimmer-turned-headteacher-Helen-Smart-dead-four-year-old-daughter-heartbreaking-video-shows-mother-paddleboarding-hours-sudden-death-aged-42.html" target="_blank" rel="noopener">MailOnline</a>, "Heidi had woken up in the night and tried to get into bed with her. She said to her daddy, 'Mummy won't wake up''. He said, 'Oh, she must be very tired Heidi - you go back to bed'." "He put the torch on and he said later that when he looked he could tell." Linda continued, "We're distraught. They don't know what it is but they think it must have happened shortly after she went to bed. She just died in her sleep." Just hours before her sudden passing, Helen and her family had been paddle boarding in the north of England, while on a trip for her brother Robert's 40th birthday. Helen had not been suffering with any illnesses her family knew of. Linda said, "At midnight, she went to bed telling me: 'I'll go to bed now mum as I know I'll be woken at 6am by Heidi. I just want to get some sleep in as I've had a long day.'" Linda was then woken by Robert at 4am who said, "Mum, dad, you need to keep up - we think Helen's died." Smart's father John said he and his wife "can't comprehend how she could simply go to sleep and not wake up." Helen became a school principal after her retirement from swimming and was enjoying her new life. Craig Smart took to her school's Facebook page to say his wife "loved the school, staff, children and parents so much." "She was so proud to reach her goal of being Head Teacher," he continued. "She used to say to me all the time she could never see herself at another school. She was Worsley Mesnes through and through! I remember only last week she said her goal was to get the school to outstanding and that she had the right staff to achieve this!" "I hope you all keep learning like champions. Please learn from this and live your best life, no regrets, take lots of photos, make memories and keep smiling just like Helen always did!" he added. Image credits: Twitter / Getty Images

"I can’t a fjord it": Inside one of the world’s most extreme restaurants

One of the world's most extreme restaurants has gone viral and not only for its unique location and shape, but also its exclusive dining experience that's eerily similar to 2022 horror film The Menu. Restaurant Iris is located inside a giant silvery orb in Hardangerfjord, the second largest Fjord in Norway. The four-storey structure, called the Salmon Eye is inspired by - you guessed it - the shape of a fish eye, and it is quite a sight to behold. The Salmon Eye is covered in 9,000 steel plates to emulate fish scales, weighing a whopping 1,256 tonnes and an impressive diameter of 25 metres, with one sub-surface floor that boasts a panoramic view of the Fjord. The restaurant itself can only be accessed by an electric boat off the shore of Rosendal, as guests are treated to "an exclusive expedition dining-journey" which offers an 18-course meal and panoramic views. The 24-seat restaurant is run by Head Chef Anika Madsen, and prior to having their main meal, guests are taken to the chef's boathouse on the nearby island of Snilstveitoy, for a "welcoming snack". The menu is designed to showcase "the most local ingredients possible", which reflects Madsen's "commitment to sustainability" and her "passion for discovering new ingredients from the ocean". Mari Eriksmoen posted the viral video on TikTok which has racked up over eight million views. "This spectacular just opened in the middle of the Hardangerfjord in Norway," she started in the clip with a shot of the structure floating in the middle of the fjord. She described the experience of walking into the restaurant "like entering a spaceship," and was mesmerised by the "insane views". Once the evening kicks off, guests indulge in a multi-sensory experience where they were instructed to pick a "cracker" hanging from the ceiling after watching a "short movie about food waste". Another TikTok user compared it to the extraterrestrial spacecraft from the 2016 sci-fi film Arrival. However many other users compared the dining experience to 2022 horror film The Menu, where a group of guests eat at an exclusive restaurant on a remote island and face dire consequences. "Did we learn nothing from The Menu?" commented one user with the crying face emoji. "I know how this movie ends," wrote another user. "I can’t a fjord it," joked a third. The dining experience aims to "blend gastronomy and activism on a global scale" as they hope to raise awareness on the the challenges and threats to the global food system. "The menu at Iris reads like a story, " a statement said. "A story about the challenges and threats to the global food system, but also with ideas and suggestions for future innovations, that can help bring us closer to solving them." The tasting menu itself is priced at 3,200 Norwegian Krone ($316) with an optional wine pairing for 2,500 Norwegian Krone ($247). For those who want to visit the Salmon Eye, but don't want to dine in, they can buy a ticket for a two-hour "learning experience" at the centre priced at 349 Norwegian Krone ($34).

Why can’t we just tow stranded whales and dolphins back out to sea?

<a href="https://theconversation.com/profiles/vanessa-pirotta-873986">Vanessa Pirotta</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> On Tuesday night, a pod of almost 100 long-finned pilot whales stranded itself on a beach on Western Australia’s south coast. Over the course of Wednesday, more than 100 parks and wildlife staff and 250 registered volunteers worked tirelessly to try to keep alive the 45 animals surviving the night. They used small boats and surf skis to try to get the pilot whales into deeper water. Volunteers helped keep the animals’ blowholes above water to prevent them drowning, and poured water on them to cool them down. Our rescue efforts were, sadly, unsuccessful. The animals (actually large ocean-going dolphins) able to be towed or helped out to deeper water turned around and stranded themselves again, <a href="https://www.facebook.com/watch/?v=228337910167574&ref=sharing">further down the beach</a>. Sadly, they had to be euthanised. Unfortunately, towing whales and dolphins is not simple. It can work and work well, as we saw in Tasmania last year, when dozens of pilot whales were rescued. But rescuers have to have good conditions and a fair dash of luck for it to succeed. <h2>Rescuing beached whales is hard</h2> When we try to rescue stranded whales and dolphins, the goal is to get them off the sandbars or beach, and back into deep water. Why is it so difficult? Consider the problem. First, you have to know that a pod has beached itself. Then, you have to be able to get there in time, with people skilled in wildlife rescue. These animals are generally too big and heavy to rely on muscle power alone. To get them out far enough, you need boats and sometimes tractors. That means the sea conditions and the slope of the beach have to be suitable. Often, one of the first things rescuers might do is look for those individuals who might be good candidates to be refloated. Generally, these are individuals still alive, and not completely exhausted. If rescuers have boats and good conditions, they may use slings. The boats need to be able to tow the animals well out to sea. Trained people must always be there to oversee the operation. That’s because these large, stressed animals could seriously injure humans just by moving their bodies on the beach. There are extra challenges. Dolphins and whales are slippery and extremely heavy. Long-finned pilot whales can weigh up to 2.3 tonnes. They may have never seen humans before and won’t necessarily know humans are there to help. They’re out of their element, under the sun and extremely stressed. Out of the water, their sheer weight begins to crush their organs. They can also become sunburnt. Because they are so efficient at keeping a comfortable temperature in the sea, they can overheat and die on land. Often, as we saw yesterday, they can’t always keep themselves upright in the shallow water. And to add to the problem, pilot whales are highly social. They want to be with each other. If you tow a single animal back out to sea, it may try to get back to its family and friends or remain disorientated and strand once again. Because of these reasons – and probably others – it wasn’t possible to save the pilot whales yesterday. Those that didn’t die naturally were euthanised to minimise their suffering. <h2>Successful rescues do happen</h2> Despite the remarkable effort from authorities and local communities, we couldn’t save this pod. Every single person working around the clock to help these animals did an amazing job, from experts to volunteers in the cold water to those making cups of tea. But sometimes, we get luckier. Last year, 230 pilot whales beached themselves at Macquarie Harbour, on Tasmania’s west coast. By the time rescuers could get there, <a href="https://www.theguardian.com/australia-news/2022/sep/27/44-pilot-whales-rescued-and-returned-to-sea-after-mass-stranding-at-tasmanian-beach">most were dead</a>. But dozens were still alive. This time, conditions were different and towing worked. Rescuers were able to bring boats close to shore. Surviving pilot whales were helped into a sling, and then the boat took them far out to sea. Taking them to the same location prevented them from beaching again. <h2>Every stranding lets us learn more</h2> Unfortunately, we don’t really know why whales and dolphins strand at all. Has something gone wrong with how toothed whales and dolphins navigate? Are they following a sick leader? Are human-made undersea sounds making it too loud? Are they avoiding predators such as killer whales? We don’t know. We do know there are stranding hotspots. Macquarie Harbour is one. In 2020, it was the site of one of the worst-ever strandings, with up to 470 pilot whales stranded. Authorities were able to save 94, drawing on trained <a href="https://www.theguardian.com/environment/2020/sep/25/death-at-hells-gates-rescuers-witness-tragic-end-for-hundreds-of-pilot-whales-on-australian-coast">rescue experts</a>. We will need more research to find out why they do this. What we do know suggests navigational problems play a role. That’s because we can divide whales and dolphins into two types: toothed and toothless. Whales and dolphins with teeth – such as pilot whales – appear to beach a lot more. These animals use echolocation (biological sonar) to find prey with high-pitched clicks bouncing off objects. But toothless baleen whales like humpbacks (there are no dolphins with baleen) don’t use this technique. They use low-frequency sounds, but to communicate, not hunt. So – it is possible to save beached whales and dolphins. But it’s not as easy as towing them straight back to sea, alas.

Can’t afford a gym membership or fitness class? 3 things to include in a DIY exercise program

<a href="https://theconversation.com/profiles/lewis-ingram-1427671">Lewis Ingram</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> With the rising cost of living, gyms memberships and fitness classes are becoming increasingly unaffordable. But the good news is you can make <a href="https://pubmed.ncbi.nlm.nih.gov/28655559/">just as much progress at home</a>. Cardiovascular endurance, muscle strength and flexibility are the <a href="https://www.acsm.org/docs/default-source/publications-files/acsms-exercise-testing-prescription.pdf?sfvrsn=111e9306_4">most important</a> components of fitness. And each can be trained with little or no equipment. Let’s look at why – and how – to fit them into your DIY exercise program. <h2>1. Cardiovascular endurance</h2> Cardiovascular endurance exercise (or “cardio”) forces the heart and lungs to increase the supply of oxygen to the working muscles. Heart disease is a <a href="https://www.who.int/news-room/fact-sheets/detail/the-top-10-causes-of-death">leading cause of death</a> and cardiovascular endurance exercise helps keep the heart healthy. The best thing about cardio is you don’t need any fancy equipment to do it. Walking, jogging and running are great options, as are cycling, skipping rope and swimming. There are two approaches to maximise cardiovascular endurance: <ul> <li> <a href="https://pubmed.ncbi.nlm.nih.gov/8897392/">high-intensity interval training</a> (HIIT) – short bouts of hard exercise (around 80% to 95% of your maximum heart rate) interspersed with lower intensity recovery periods (around 40% to 50% of your maximum heart rate) </li> <li> <a href="http://pubmed.ncbi.nlm.nih.gov/26664271/">low-intensity steady-state</a> (LISS) exercise – aerobic activity performed continuously at a low-to-moderate intensity (around 50% to 65% of your maximum heart rate) for an extended duration. </li> </ul> Both are great options. While high-intensity interval training can be more time efficient, low-intensity steady-state training might be more enjoyable and easier to sustain long-term. No matter what you choose, <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">aim for</a> a minimum of 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity cardiovascular exercise each week. For example, you could try 30 minutes, five days per week of low intensity cardio, or 25 minutes, three days per week of high-intensity activity, or a combination of the two. How do you know if you’re exercising at the right intensity? Smart watches that measure heart rate can help to monitor intensity. Or you can rely on the good old-fashioned <a href="https://pubmed.ncbi.nlm.nih.gov/25536539/">talk test</a>. During low-intensity activity, you should be able to speak in full sentences. Conversely, short phrases (initially) or single words (towards the end) should be all that’s manageable during high-intensity exercise. <h2>2. Muscle strength</h2> Next is muscle strength, which we train through resistance exercise. This is important for bone health, balance and metabolic health, especially as we age and our <a href="https://pubmed.ncbi.nlm.nih.gov/30276173/">muscle mass and strength declines</a>. Aim for two days per week of whole-body resistance exercise performed at a moderate or <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">greater intensity</a>. Try to build two weekly sessions that target the major muscle groups. This could include: <ul> <li>squats – lower to the ground from standing by bending the hips, knees, and ankles while keeping the chest up tall before returning to standing by straightening the hips, knees and ankles</li> </ul> <ul> <li> <a href="https://www.physio-pedia.com/Hip_Hinge">hinges</a> – fold forward at the hips by pushing your bottom back to the wall behind you, keeping your back straight. A slight bend in the knees is fine but aim to keep your shins vertical </li> <li> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7196742/">push-ups</a> – if a full push-up is too difficult, you can place your hands on a raised surface such as a step or a chair </li> <li> horizontal and vertical pull ups – using something like a portable chin up bar, which you can buy from sports supply stores </li> <li> vertical pushes – pushing an object (or weight) vertically from the top of your chest to an overhead position. </li> </ul> Once you have selected your exercises, <a href="https://pubmed.ncbi.nlm.nih.gov/35873210/">perform</a> 2–3 sets of 8–12 repetitions at a moderate to greater intensity, with about 90 seconds rest between each set. As you progress, continue to challenge your muscles by adding an extra set to each exercise, or including dumbbells, changing body position or wearing a backpack with weights. The goal should be to progress slightly each session. However, if you have any underlying health conditions, disabilities, or are unsure how best to do this, see an exercise physiologist or physiotherapist. <h2>3. Flexibility</h2> Improved flexibility can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3273886/">increase your range of motion</a> and improve your ability to manage daily life. While we don’t know the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3273886/">best means of increasing flexibility</a>, the most basic and readily accessible is static <a href="https://www.topendsports.com/testing/flex.htm">stretching</a>. Here, we lengthen the muscle – for example, the hamstrings, until we feel a “stretching” sensation. Hold that position for 15–30 seconds. While the precise intensity of this stretching sensation <a href="https://pubmed.ncbi.nlm.nih.gov/26347668/">remains elusive</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29506306/">around 5–10 minutes</a> per week per <a href="https://exrx.net/Lists/Directory">muscle group</a>, spread across five days, seems to provide the best results. <h2>How to stick with it?</h2> The best exercise is the one that gets done. So, whatever you choose, make sure you enjoy it. After all, it’s about creating an ongoing commitment to exercise that will deliver long-term health benefits. It’s also important to ensure you’re ready to exercise, especially if you have any underlying health issues, have been previously inactive, or are unsure how to start. A <a href="https://www.ausactive.org.au/apss">pre-exercise screening</a> can help you to determine whether you should see a doctor or allied health professional before starting an exercise program and for guidance on the next steps. <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/206204/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lewis-ingram-1427671">Lewis Ingram</a>, Lecturer in Physiotherapy, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>; <a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, Lecturer in Exercise Science, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a>, and <a href="https://theconversation.com/profiles/saravana-kumar-181105">Saravana Kumar</a>, Professor in Allied Health and Health Services Research, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

10 reasons humans kill animals – and why we can’t avoid it

<a href="https://theconversation.com/profiles/benjamin-allen-100036">Benjamin Allen</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> As long as humans have existed, they’ve killed animals. But the necessity of some types of animal killing are now questioned by many. So can humans ever stop killing animals entirely? And if not, what’s the best way forward? <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062">New research</a> I led investigates these questions. My colleagues and I identified the ten main reasons why humans kill animals. We found the need for some types of animal killing is questionable, but several forms are inescapable – a necessary part of humanity’s involvement in a single, functioning, finite global food web. But the debate doesn’t end there. Even if humans must kill animals in some cases, they can modify their behaviours to improve the welfare of animals while they are alive, and to reduce an animal’s suffering when it is killed. Doing so may improve the lives of animals to a greater extent than efforts to eliminate human killing entirely. <h2>Why humans kill animals</h2> Critics of animal-killing come from a variety of perspectives. Some oppose it on <a href="http://refhub.elsevier.com/S0048-9697(23)03906-2/rf0005">moral grounds</a>. Others claim animals should have <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13494">rights equal</a> to humans, and say animal killing is a criminal act. Many people view any animal killing as <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13126">cruel</a>, regardless of whether the animal suffers. But as valid and important as these views might be, they largely fail to address why humans kill animals – and why in many cases, it can’t be avoided. Our research sought to shed light on this. We focus our discussion on vertebrate animals which are almost universally recognised as “sentient” (or able to perceive and feel things). We identified ten main reasons humans kill animals: 1. Wild harvest or food acquisition: such as killing wild animals for meat 2. Human health and safety: such as reactively killing an animal when it attacks you 3. Agriculture and aquaculture: such as killing that occurs in the global meat industries, or killing required to produce crops 4. Urbanisation and industrialisation: such as clearing bushland to build homes 5. Wildlife control: such as programs that eradicate introduced animals to stop them killing native ones 6. Threatened species conservation: such as unintentionally killing animals when relocating them 7. Recreation, sport or entertainment: such as trophy hunting or bull fighting, and animal killing required to feed domestic pets 8. Mercy or compassion: such as euthanasing an animal hit by a car 9. Cultural and religious practice: such as animal sacrifice during the Islamic celebration of <a href="https://www.theguardian.com/world/2023/jul/01/sydney-muslims-take-eid-al-adha-livestock-sacrifice-into-their-own-hands">Eid al-Adha</a>, or those associated with the <a href="https://www.jstor.org/stable/1594756">Yoruba</a> religion of West Africa 10. Research, education and testing: such as the laboratory use of rodents or primates. <h2>Understanding human killing behaviour</h2> So how best should we understand the above types of animal killing? Our research considers them in ecological terms – as behaviours consistent with our predatory and competitive roles in the global food web. Such behaviours are intended to improve human prospects for acquiring food or to protect and enhance life. These are innate life objectives for any sentient animal. Maintenance of all life on Earth requires obtaining, using, disposing of and recycling chemical elements. Ecosystems can be thought of as a “battleground” for these elements. <a href="https://theconversation.com/peter-singers-fresh-take-on-animal-liberation-a-book-that-changed-the-world-but-not-enough-205830">Some people argue</a> that directly killing animals is unacceptable, or that adopting certain lifestyles or diets, such as veganism, can eliminate or greatly reduce animal killing. But in our view, achieving a no-killing lifestyle is a physical and ecological impossibility. For instance, most plant foods come from crops grown on land where animals have been <a href="https://www.mdpi.com/2076-2615/11/5/1225">killed or displaced</a>. And while an animal-free diet for humans might temporarily reduce the number of animals killed, this won’t last forever. As human populations continue to grow, more land will eventually be needed to meet their food requirements. At that point, humans will have to directly or indirectly kill animals again or risk dying themselves. Humans also need space to live, which <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb1045">results in</a> animal killing when habitat is razed. Of course, in rare cases an individual human may live without killing animals directly. Perhaps they live in a cave in the forest, and get sustenance from wild berries and mushrooms. But that human still lives inside the food web, and is competing against other animals for finite resources. In these cases, other animals may suffer and die because the human’s use of berries and caves leaves less food and space for them. Even if that human could do no harm at all to any animal, it’s still impossible for societies at large to live in this way. Some forms of animal killing are certainly not essential for human existence. Good examples are recreational hunting, euthanasia or keeping pets (which requires killing animals to feed them). And we certainly do not condone direct human participation in all forms of animal killing. It’s also important to note that in many cases, current levels of animal killing are <a href="https://www.opsociety.org/stop-unsustainable-fishing/">unsustainable</a>. Human populations have increased to the point where animals must be killed on enormous scales to feed, house and protect ourselves. If this continues, animal <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb0905">populations</a> will <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb0910">crash</a> – and with them, human populations. Nevertheless, we maintain that the overall necessity of animal killing is an unavoidable reality for humanity as a whole. A variety of direct and indirect forms of animal killing will undoubtedly remain an ongoing human endeavour. <h2>Taking responsibility</h2> So what are the implications of all this? We hope our research leads to a constructive dialogue, which starts with accepting that human existence on Earth is dependent on animal killing. It should then focus on the nuances of animal welfare and sustainability. Humans are the only known animals with an ethical or moral conscience. That means we have <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&fr=RR-2&rr=7e2e8f44ae1aaae3#bbb0650">a responsibility</a> to assume a stewardship role over all other animals, to resolve negative interactions between them as best as possible, and to ensure good welfare for as many animals as we can. Directing our attention in this way is likely to improve the lives of animals to a greater extent than trying to prevent humans from killing animals altogether – efforts my colleagues and I believe will ultimately be in vain.<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/209218/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/benjamin-allen-100036">Benjamin Allen</a>, Wildlife ecologist, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why can’t I use my phone or take photos on the airport tarmac? Is it against the law?

<a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Mobile phones are not allowed to be used while on a plane because they can interfere with the aeroplane’s navigation instruments and <a href="https://theconversation.com/heres-the-real-reason-to-turn-on-aeroplane-mode-when-you-fly-188585">cause various safety and social issues</a>. As soon as the plane lands, we’re permitted to turn off flight mode, but at some airports we can’t get much of a signal. That’s because airports are known as mobile signal “<a href="https://thepointsguy.com/news/slow-connection-airport-tarmacs/">dead zones</a>” due to a lack of mobile towers – they can’t be placed at the airport itself due to height restrictions. Any nearby mobile towers would be located away from the airport’s runway systems to avoid interfering with the aeroplane’s flight path, especially take-off and landing direction. Most airports put up indoor repeater antennas within the airport terminal; these help increase the mobile signal strength coming from the nearest mobile tower somewhere near the airport. But you won’t be allowed to make calls while walking away from the plane, anyway. <h2>Why can’t I use my phone on the tarmac?</h2> As we are taxiing in, the <a href="https://www.qantas.com/au/en/qantas-experience/onboard/communication.html">cabin crew</a> remind us not to smoke outside of designated areas at the terminal and not to use our mobile phones until we are inside the terminal building. If you exit the plane down the rear stairs, why aren’t you allowed to use your phone once away from the aeroplane, if you can get a signal? Surely it won’t affect navigation. The answer is manifold, and regulations aren’t the same across the world. In Australia, a <a href="https://www.casa.gov.au/operations-safety-and-travel/travel-and-passengers/onboard-safety-and-behaviour/using-your-electronic-devices-flights">government regulation</a> prohibits the use of mobile phones on the tarmac – the aeroplane movement and parking area of the airport. You won’t be fined if you whip your phone out while walking to the terminal, but the airline may admonish you for not following the rules. However, if you decide to (<a href="https://www.smh.com.au/national/victoria/woman-arrested-after-running-onto-tarmac-at-melbourne-airport-20151125-gl7bkq.html">run around on the tarmac</a>, you could get arrested by federal police. The airport tarmac is very busy not just with aircraft, but also baggage carts, catering trucks, aeroplane waste removal trucks, and fuel trucks. Getting passengers off the tarmac and into the terminal building quickly and safely is a priority for the staff. If you are distracted while walking to the terminal building because you’re talking on your phone, it can be <a href="https://www.theguardian.com/us-news/2023/jan/25/alabama-airport-worker-killed-jet-engine-safety-warnings">highly dangerous and even deadly</a> if you end up too close to an operating plane. An operating jet engine is extremely hot and has a strong exhaust. Additionally, the front of the engine has a low-pressure area called an <a href="https://www.ukfrs.com/guidance/search/aircraft-systems-and-construction">ingestion zone</a> that can suck in a person. Ground staff are trained to stay at least ten metres away from this area. However, this information is not shared with the passengers. <h2>A myth about fuel</h2> You may have heard that mobile phones are a fire hazard near fuel, and aeroplanes are, of course, refuelled on the tarmac. However, the chances of fuel catching fire during this process are extremely low, because the refuelling truck is <a href="https://safetyfirst.airbus.com/safe-aircraft-refuelling/">bonded and “grounded” to the plane</a>: the operator attaches a wire to the aircraft to move built-up static electricity to the ground to prevent any chance of a spark. <figure class="align-right zoomable"><figcaption></figcaption></figure> There have been stories in the press about mobile phones sparking <a href="https://www.verizon.com/about/news/vzw/2014/12/fact-or-fiction-using-a-cell-phone-at-the-gas-station-can-cause-a-fire">fires at petrol stations in Indonesia and Australia</a>, but these turned out to be inaccurate. There is <a href="https://www.nfpa.org/assets/files/AboutTheCodes/30A/FI%20-%20NFPA%2030A-2015%20Para%208.3.1%20-%20Attachments%2014-19.2017-04-04.pdf">no evidence a phone can spark a fire at a fuel pump</a>, despite the warning labels you might see. Either way, the chances of a mobile phone causing this on the tarmac with a refuelling truck that is grounded to the aeroplane are extremely low, not least because the passenger permitted areas and refuelling areas are completely separated. <h2>Why are we told not to take photos on the tarmac?</h2> This rule varies from airport to airport depending on their <a href="https://www.tsa.gov/travel/frequently-asked-questions/can-i-film-and-take-photos-security-checkpoint">security processes</a>. Such restrictions are carryovers from the changes to airport security following the <a href="https://heinonline.org/HOL/P?h=hein.journals/jlecono50&i=739">September 11 2001 terrorist attacks</a>. The now federalised security teams, TSA (Transportation Security Administration) in the United States and the Department of Home Affairs in Australia, change their processes frequently to prevent having any identifiable patterns that could be used to create a security breach. The increased security measures also mean new technologies were introduced; airport security sections do not want photos taken of how they operate. The airport security process is a major choke point in the flow of passenger movement due to the screening process. If a passenger is perceived to be slowing the process down by taking photos or talking on their phone, they will be reminded to turn off their device and/or stop taking photos of security personnel and equipment. If you refuse to follow the rules of the screening process, you will be <a href="https://www.homeaffairs.gov.au/about-us/what-we-do/travelsecure/passenger-screening">denied entry</a> into the airport terminal gate area and miss your flight. Can you also get arrested for using your phone? Depends on the airport and country. I, for one, do not want to find out.<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/207926/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, Professor/Head of Aviation, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Tips

No, you can’t reverse ageing by injecting ‘young blood’ and fasting. But that doesn’t stop people trying

<a href="https://theconversation.com/profiles/rachael-jefferson-buchanan-297850">Rachael Jefferson-Buchanan</a>, <a href="https://theconversation.com/institutions/charles-sturt-university-849">Charles Sturt University</a> Like many celebrities and entrepreneurs, 45-year-old US tech billionaire Bryan Johnson is <a href="https://www.smh.com.au/lifestyle/health-and-wellness/taking-the-blood-of-your-17-year-old-son-anti-ageing-has-gone-too-far-20230530-p5dcd6.html">trying to reverse the ageing process</a>. Spending an average of US$2 million a year on an anti-ageing regimen, Johnson <a href="https://medium.com/future-literacy/at-45-i-now-age-slower-than-the-average-10-year-old-6932448fc608">claims</a> he now ages slower than some children. He explains: “the pace my body accumulates ageing damage is less than the average ten year old”. Many of Johnson’s age-reversal methods are questionable, involve dodgy science, and have known side effects. While you can’t stop the ageing process, and the gradual decline our bodies experience as we advance in years, there are some things we can all do – for free – to maintain our health as we age. <h2>What does Johnson do? And is it scientific?</h2> Fasting Johnson reports fasting for 23 hours a day. He then eats <a href="https://medium.com/future-literacy/one-meal-23-hr-fast-100-nutrition-18187a2f5b">one meal a day</a>: 2,250 calories of nutrient-dense food “customised” to his body’s needs. Eating for time-restricted periods in the day can have a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9650338/">positive effect</a> on how we <a href="https://pubmed.ncbi.nlm.nih.gov/29955217/">metabolise nutrients</a>, inflammation levels, hormonal regulation, and <a href="https://www.health.harvard.edu/blog/how-good-is-your-cardiometabolic-health-and-what-is-that-anyway-202208182803">cardiometabolic health</a> (blood sugar, <a href="https://www.mayoclinic.org/diseases-conditions/high-blood-cholesterol/in-depth/triglycerides/art-20048186">triglycerides</a>, cholesterol, blood pressure, BMI and waist circumference). However, a Spartan-like food intake can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2121099/">impair</a> how our body responds to sugar (known as glucose tolerance). And it’s not necessarily any more effective for weight maintenance than <a href="https://pubmed.ncbi.nlm.nih.gov/29419624/">reducing calorie intake at each meal</a>. Large-scale, long-term human trials are needed to confirm the <a href="https://pubmed.ncbi.nlm.nih.gov/34728336/">limited risk-benefit</a> findings of fasting. Acid peels Johnson has weekly <a href="https://www.asds.net/skin-experts/skin-treatments/chemical-peels/chemical-peels-for-aging-skin">acid peels</a> (which use a mild acid to exfoliate the skin) to maintain a “youthful glow”. But you cannot smooth sagging facial skin or remove deep scars or wrinkles. Acid peels also <a href="https://www.mayoclinic.org/tests-procedures/chemical-peel/about/pac-20393473">come with risks</a>, including organ damage, infection, scarring and swelling. Plasma infusions Perhaps the most bizarre youth-inducing procedure Johnson has attempted is receiving blood transfusions from his 17-year-old son. US biotech companies have explored <a href="https://www.theguardian.com/society/2020/feb/02/could-young-blood-stop-us-getting-old-transfusions-experiments-mice-plasma">plasma infusions</a> to tackle age-related diseases in humans for decades. But there are no proven clinical benefits. <a href="https://www.redcrossblood.org/donate-blood/blood-donation-process/what-happens-to-donated-blood/blood-transfusions/risks-complications.html">Side effects from blood transfusions</a> include blood-borne infections, fever and allergic reactions. <h2>Historical attempts to stay youthful</h2> Humans have been experimenting with <a href="https://academic.oup.com/biomedgerontology/article/59/6/B515/662071">anti-ageing methods for centuries</a>. These have included all sorts of behavioural and lifestyle practices that are quirky, questionable, and even sadistic. Ancient practices included <a href="https://www.marieclaire.com/beauty/news/a14382/anti-aging-beauty-through-history/">crocodile dung face masks</a>, which the Greeks and Romans used to brighten their complexions. Romans also used <a href="https://beautytap.com/2019/03/donkey-milk">donkey milk</a> and <a href="https://www.ancient-origins.net/history/swans-fat-crocodile-dung-and-ashes-snails-achieving-beauty-ancient-rome-003240">swan fat</a> to minimise wrinkles, due to their acclaimed rejuvenating properties. <a href="https://www.livescience.com/44071-cleopatra-biography.html">Cleopatra</a> apparently took daily baths in sour donkey milk. To sustain this lavish habit, she had a <a href="https://www.naturanecosmetics.com/en/content/26-faits-historiques">herd of 700 donkeys</a>. Sour milk contains <a href="https://science.jrank.org/pages/3780/Lactic-Acid-Lactic-acid-in-foods.html">lactic acid</a>, a naturally occurring <a href="https://www.mecca.com.au/edits/ingredients/alpha-hydroxy-acids/">alpha-hydroxy acid (AHA)</a> that exists in many modern-day exfoliants. So this idea was grounded in basic science, at least. <figure class="align-center "><img src="https://images.theconversation.com/files/530478/original/file-20230607-27-bv0w1t.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/530478/original/file-20230607-27-bv0w1t.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530478/original/file-20230607-27-bv0w1t.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530478/original/file-20230607-27-bv0w1t.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530478/original/file-20230607-27-bv0w1t.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530478/original/file-20230607-27-bv0w1t.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530478/original/file-20230607-27-bv0w1t.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="Milk bath with dried fruits and flowers" /><figcaption>Don’t waste milk on a bath. <a class="source" href="https://www.shutterstock.com/image-photo/bath-milk-flowers-1051210370">Shutterstock</a></figcaption></figure> During the 16th and 17th century, “Countess Dracula” aka <a href="https://en.wikipedia.org/wiki/Elizabeth_B%C3%A1thory">Elizabeth Bathory</a> allegedly resorted to serial killing to quench her thirst for youthfulness, <a href="https://www.nationalgeographic.com/travel/article/the-bloody-legend-of-hungarys-serial-killer-countess">bathing in the blood of her young victims</a>. <h2>The quest continues with cryotherapy</h2> Fountain of youth fixations have inspired many contemporary anti-ageing trends. Exposure to cold is a firm favourite. <a href="https://www.nature.com/articles/s43587-023-00383-4">Some research</a> suggests this could have <a href="https://neurosciencenews.com/cold-aging-22928/">benefits</a> relating to longevity, by slowing cellular degeneration, <a href="https://www.cryo.com.au/anti-ageing-benefits-of-whole-body-cryotherapy/">stimulating collagen and elastin production</a>, increasing the metabolism, and reducing inflammation. Dutch motivational speaker Wim Hof includes <a href="https://www.wimhofmethod.com/cold-water-immersion">cold water immersion</a> as one of the three pillars of his <a href="https://www.wimhofmethod.com/">Wim Hof Method</a> to “increase mind-body connection”.

However, the <a href="https://www.medicinenet.com/what_are_the_side_effects_of_cryotherapy/article.htm">risks of cryotherapy</a> include bone fractures, frostbite, nerve damage, bleeding, cramping, swelling and skin infections. <h2>So what can we do to age well?</h2> Two of the more mainstream anti-ageing methods that Johnson recommends are the daily self-care habits of sleep and exercise. He has a <a href="https://medium.com/future-literacy/sleep-and-impulse-control-87e844218ff2">strict sleep schedule</a> that involves retiring to bed at 8pm, with a one-hour wind-down in a darkened room. Adults report poorer sleep quality and difficulty being able to sleep for long enough <a href="https://www.news-medical.net/health/How-Does-the-Suprachiasmatic-Nucleus-(SCN)-Control-Circadian-Rhythm.aspx">as they age</a>. Sleeping too much or too little is <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2023.1043347/full">associated with</a> a greater risk of obesity, heart disease and <a href="https://theconversation.com/research-check-can-sleeping-too-much-lead-to-an-early-death-101323">premature death</a>.

"I can't hear you!": New feature set to do away with subtitles

Nothing is more annoying than sitting in front of your TV, eager to watch your favourite show only for the dialogue to be completely wiped because of cars passing by or a plane taking off. Not being able to hear the dialogue in a TV show or movie, especially in an action or crime-driven blockbuster where anything exploding masks all dialogue has been an everlasting problem for viewers. Netflix has revealed that 40 per cent of subscribers have subtitles on at all times while surveys in the US and UK saw anywhere between 60 and 70 per cent of young viewers as frequent users of subtitles. If you’re using subtitles for the purpose of hearing the dialogue rather an accessibility reasons, streaming giant Amazon is introducing a new feature that could eradicate the need to turn them on because of the sound mix. The feature is called ”dialogue boost" and it raises the volume of the dialogue track relative to the score, ambient sound or effects. Although Amazon has so generously offered this solution to subscribers, the dialogue boost feature will only be available on a handful of Amazon Prime Video’s originals, like Beautiful Boy, Being The Ricardos, Jack Ryan and The Marvelous Mrs Maisel. A similar feature already appears on some expensive sound systems and TV sets, but Amazon boasts it’s the first streaming platform to roll it out worldwide. To work the feature, select it from the audio and subtitles drop-down menu on an individual title, there will be two options to select from, “English Dialogue Boost: High” or “English Dialogue Boost: Medium”. The title page for a TV series or movie will show whether the dialogue boost is available. According to Variety, the helpful feature was originally designed for hearing-impaired viewers. Rest assured, if you struggle to hear the dialogue due to the sound mix, there's help on the way, granted it's exclusive to Amazon. Image credit: Shutterstock

“Surely a baby can’t do that”: Fitness guru stuns fans

British fitness coach has left fans shocked after posting a photo of his seven-month-old hanging from a pull-up bar. The fitness guru, and founder of the popular fitness app The Body Coach, posted a series of sweet snaps to his Instagram of a recent family holiday to California, USA. The photo has gained a lot of traction online among his 4.6 million followers. The image shows baby Leny dressed in a white onesie dangling from a tall monkey bar at the beach while Wicks looks on proudly. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/Cq3C-ywLb6k/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/Cq3C-ywLb6k/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Joe Wicks (@thebodycoach)</a> </div> </blockquote> Many followers were concerned about Leni, calling out the dad-of-three for such a “risky” pose. "Jesus, is the first pic photoshopped?" wrote one follower. "How is the first pic even possible?!" asked another. "Surely a baby can't do that?” Another added, ”Is that safe for her shoulders and joints to hang onto bars supporting her own weight like that? "Please don't do that to your baby. She would be frightened," wrote a fourth, sparking a debate in the comment section. "She doesn't look fine to me and a lot of people agree. This is cruel and would instinctually cause fear in the baby. If you think that's OK you are a cruel person.” Some were impressed by the “super baby”, taken back by her strength for her age and defended Wicks against his critics. "That first picture of Leni is amazing! You need to recreate that every year!" wrote one follower. "I love how you let them take risks.” "Your kids have iron man genes," another added. "Wow Leni is strong holding on to the monkey bars, that's brilliant.” Those that came to the dad’s defence reminded critics that the baby would not have been there for long. "My babies/toddlers could all do this when they were young. It was only for a few seconds. We were there ready to catch them," one said. "It is called the palmar grasp reflex and it is normal for babies," wrote another. A child gymnastics company, Little Gym UK also came to the dad’s defence, saying, "For those questioning if it's photoshopped, our classes start at four months and babies can absolutely grasp and hang this little.” While it’s no myth newborns do have a grasp reflex and the grip is often “strong enough to hold the baby’s entire weight”, experts do not advise picking up or swinging a toddler by their arms as it can lead to a common injury called Nursemaid’s elbow. Wicks has two other children with his wife Rosie, Indie, four, and Marley, three. Image credit: Instagram
