Summer holidays haven’t changed much since ancient Greece and Rome (except maybe the sand wrestling)

<p><em><a href="https://theconversation.com/profiles/konstantine-panegyres-1528527">Konstantine Panegyres</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722"><em>The University of Melbourne</em></a></em></p> <p>Imagine a summer holiday at a seaside resort, with days spent sunbathing, reading books, exploring nature and chatting with friends.</p> <p>Sounds like it could be anywhere in Australia or New Zealand in January, doesn’t it?</p> <p>This is also how the Roman emperor <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-3508?product=orecla">Julian</a> spent his summers in the 4th century CE. Towards the end of 357 CE, Julian wrote a <a href="https://www.loebclassics.com/view/emperor_julian-letters/1923/pb_LCL157.79.xml?rskey=Sa5rUn&result=1&mainRsKey=pqeNrD">letter</a> to his friend Evagrius, telling him how he spent his holidays at his grandmother’s estate as a boy and young man:</p> <blockquote> <p>Very peaceful it is to lie down there and glance into some book, and then, while resting one’s eyes, it is very agreeable to gaze at the ships and the sea.</p> <p>When I was still hardly more than a boy I thought that this was the most delightful summer residence, for it has, moreover, excellent springs and a charming bath and garden and trees.</p> </blockquote> <p>As Julian got older, though, he had less time for summer holidays. Work consumed him. Even when he was on a break, he couldn’t fully relax.</p> <p>This might sound familiar, too. It seems very little has changed from the days of the ancient Greek and Roman empires when it comes to finding time to unwind – and being on holidays, too.</p> <h2>Finding time for a break</h2> <p>Taking time off was important in ancient Greek and Roman times. Even <a href="https://www.tandfonline.com/doi/pdf/10.1080/00397677908590731">Greek and Roman slaves</a> were permitted to take a few holidays each year.</p> <p>Not everyone could enjoy their holidays, however.</p> <p>In 162 CE, <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-984">Marcus Aurelius</a>, then emperor of Rome, took four days of holiday at a resort in Alsium, a city on the coast of modern-day Italy.</p> <p>According to his friend <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-1846">Marcus Cornelius Fronto</a> (c. 95-166 CE), though, the emperor could not stop working. In a letter, Fronto <a href="https://www.loebclassics.com/view/marcus_cornelius_fronto-correspondence/1919/pb_LCL113.5.xml?mainRsKey=Q5rXrd&result=1&rskey=fAbCGr">criticises</a> Marcus for continuing to work hard rather than sleeping in, exploring the seaside, rowing on the ocean, bathing and feasting on seafood.</p> <p>Fronto amusingly says that Marcus, rather than enjoy his holiday, has instead “declared war on play, relaxation, good living, and pleasure”.</p> <h2>Going to the seaside</h2> <p>Relaxing by the coast was one of the things people in ancient Greece and Rome most enjoyed doing in the summer.</p> <p>The rich built summer residences on the coast, while people of all walks of life flocked to seaside resorts to enjoy the fresh air and cool water.</p> <p>The orator <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-3675">Libanius</a> (314-393 CE) <a href="https://www.loebclassics.com/view/libanius-oration_45_emperor_prisoners/1977/pb_LCL452.165.xml?rskey=EVUxsK&result=1&mainRsKey=ISthry">wrote</a> that the people who really enjoy life the most are those who have the freedom to “drive to their estates, visit other towns, buy land, and visit the seaside”.</p> <p>Health tourism was also a popular reason why people came to the seaside. Many ancient doctors recommended sea water and air as cures for all kinds of health problems, especially those related to the skin and respiratory system.</p> <p>For example, the doctor <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-705">Aretaeus of Cappadocia</a> (c. 150-200 CE) <a href="https://books.google.com.au/books?id=v4gIAAAAIAAJ&pg=PA463&dq=Aretaeus+sea+water&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjh-f6OiuCJAxW4dPUHHXQQH5oQ6AF6BAgEEAI#v=onepage&q=Aretaeus%20sea%20water&f=false">recommended</a> bathing in sea water, wrestling on sand and living by the sea as therapies for those who get frequent headaches.</p> <h2>Travelling abroad</h2> <p>Visiting foreign places was another of the things people in ancient Greece and Rome most enjoyed doing on their summer holidays.</p> <p>For the Romans, trips to see Greece – and in particular Athens – were especially popular.</p> <p>The Roman general <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-3396?rskey=xWdUMg&result=1">Germanicus</a> (15 BCE–19 CE) went on a tour of Greece in 18 CE, travelling from Athens eastward to Euboea, Lesbos, the coast of Asia Minor and then to Byzantium and Pontus.</p> <p>According to the Roman historian <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-6205">Tacitus</a>, Germanicus was motivated by a desire to see famous ancient sites. Like many Romans, he was fascinated by the old stories of the Greek past, so <a href="https://www.loebclassics.com/view/tacitus-annals/1931/pb_LCL249.469.xml">he was</a> “eager to make the acquaintance of those ancient and storied regions”.</p> <p>Another popular destination for ancient Greeks and Romans was Egypt, which had always been regarded as a land of wonder.</p> <p>Roman tourists could catch regular boats from <a href="https://www.romanports.org/en/the-ports/88-puteoli.html">Puteoli</a> to the great Egyptian city <a href="https://www.britannica.com/place/Alexandria-Egypt">Alexandria</a>. The trip took anywhere from one to two weeks, stopping along the way in Sicily and Malta.</p> <p>Once there, the highlights were typically the great Nile River and Pyramids. Tourists marvelled at the immense temples and walls of hieroglyphic writing.</p> <p>When Germanicus visited Egypt in 19 CE, he was so curious about the meaning of the hieroglyphics that he <a href="https://www.loebclassics.com/view/LCL249/1931/volume.xml">asked</a> an old Egyptian priest to translate some for him.</p> <p>In Alexandria, another attraction was the tomb of <a href="https://www.oxfordreference.com/display/10.1093/oi/authority.20110803095401572">Alexander the Great</a> (356-323 BCE). His body was stored in honey in a coffin made of glass. Ordinary tourists were not allowed to visit it, but VIPs like Roman emperors were.</p> <p>Tourists might also have enjoyed the different vibe in Alexandria. According to the Greek orator <a href="https://www.britannica.com/biography/Dio-Chrysostom">Dio of Prusa</a> (c. 40-110/120 CE), the atmosphere in the coastal city was relaxed, with plenty of music, chariot racing and good food.</p> <h2>Lazy summer days</h2> <p>We can probably all relate to what the writer <a href="https://oxfordre.com/classics/display/10.1093/acrefore/9780199381135.001.0001/acrefore-9780199381135-e-5134">Pliny the Younger</a> (61/62-112 BCE) said about his summer break.</p> <p>Writing on a holiday in Tuscany, he <a href="https://www.loebclassics.com/view/pliny_younger-letters/1969/pb_LCL059.95.xml?rskey=Mdlmkl&result=1">said</a> he can only work “in the lazy way to be expected during a summer holiday”. Working any other way was simply not possible.

Disney to change content warnings shown before "problematic" classics

<p>Disney will tone down the language of the content warnings on its streaming service that accompany classic movies with racial stereotypes. </p> <p>The current disclaimers played before older titles like <em>Dumbo</em> and <em>Peter Pan</em> said the film “includes negative depictions and/or mistreatment of peoples or cultures” adding, “these stereotypes were wrong then and are wrong now.”</p> <p>The new disclaimers will state: “This program is presented as originally created and may contain stereotypes or negative depictions,” and will not appear as introductory text that plays before the beginning of a film. </p> <p>The disclaimers will also only appear in the details section of certain films, where viewers will have to navigate to find it, decreasing their visibility. </p> <p>Disney will also replace its “Diversity & Inclusion” performance factor used to evaluate executive pay with a new “Talent Strategy”, according to Sonia Coleman, Disney’s senior executive vice president and chief human resources officer. </p> <p>Other rollbacks of its diversity, equity and inclusion measures include the closure of its Reimagine Tomorrow initiative, a website that highlighted stories and talent from underrepresented communities. </p> <p>Disney first added content warnings to older movies like <em>Dumbo </em>and Peter Pan in November 2019, due to racist depictions included in some of the films created by the studio in the 40s and 50s. </p> <p>Disney has become the latest major organisation to roll back its diversity measures following Donald Trump’s re-election as US President.</p> <p><em>Image: spatuletail / Shutterstock.com</em></p> <p> </p>

How we diagnose and define obesity is set to change – here’s why, and what it means for treatment

<p><em><a href="https://theconversation.com/profiles/louise-baur-5284">Louise Baur</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/john-b-dixon-11630">John B.

Brown</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Obesity is <a href="https://www.niddk.nih.gov/health-information/weight-management/adult-overweight-obesity/health-risks#:%7E:text=Having%20overweight%20or%20obesity%20increases,the%20cells%20in%20your%20body">linked to</a> many common diseases, such as type 2 diabetes, heart disease, fatty liver disease and knee osteoarthritis.</p> <p>Obesity is currently defined using a person’s body mass index, or BMI. This is <a href="https://www.who.int/news-room/fact-sheets/detail/obesity-and-overweight">calculated</a> as weight (in kilograms) divided by the square of height (in metres). In people of European descent, the BMI for obesity is 30 kg/m² and over.</p> <p>But the risk to health and wellbeing is not determined by weight – and therefore BMI – alone. We’ve been part of a global collaboration that has spent the past two years discussing how this should change. Today we publish how we think obesity should be defined and why.</p> <p>As we outline in <a href="https://www.thelancet.com/commissions/clinical-obesity">The Lancet</a>, having a larger body shouldn’t mean you’re diagnosed with “clinical obesity”. Such a diagnosis should depend on the level and location of body fat – and whether there are associated health problems.</p> <h2>What’s wrong with BMI?</h2> <p>The risk of ill health depends on the relative percentage of fat, bone and muscle making up a person’s body weight, as well as where the fat is distributed.</p> <p>Athletes with a relatively high muscle mass, for example, may have a higher BMI. Even when that athlete has a BMI over 30 kg/m², their higher weight is due to excess muscle rather than excess fatty tissue.</p> <p>People who carry their excess fatty tissue <a href="https://www.abc.net.au/news/health/2017-09-06/waist-size-why-it-matters-and-when-its-a-risk/8839708">around their waist</a> are at greatest risk of the health problems associated with obesity.</p> <p>Fat stored deep in the abdomen and around the internal organs can release damaging molecules into the blood. These can then <a href="https://theconversation.com/body-fat-deep-below-the-surface-is-a-toxic-risk-especially-for-your-heart-146307">cause problems</a> in other parts of the body.</p> <p>But BMI alone does not tell us whether a person has health problems related to excess body fat. People with excess body fat don’t always have a BMI over 30, meaning they are not investigated for health problems associated with excess body fat. This might occur in a very tall person or in someone who tends to store body fat in the abdomen but who is of a “healthy” weight.</p> <p>On the other hand, others who aren’t athletes but have excess fat may have a high BMI but no associated health problems.</p> <p>BMI is therefore an imperfect tool to help us diagnose obesity.</p> <h2>What is the new definition?</h2> <p>The goal of the <a href="https://pubmed.ncbi.nlm.nih.gov/36878238">Lancet Diabetes & Endocrinology Commission on the Definition and Diagnosis of Clinical Obesity </a>was to develop an approach to this definition and diagnosis. The commission, established in 2022 and led from King’s College London, has brought together 56 experts on aspects of obesity, including people with lived experience.</p> <p>The commission’s <a href="https://www.thelancet.com/commissions/clinical-obesity">definition and new diagnostic criteria</a> shifts the focus from BMI alone. It incorporates other measurements, such as waist circumference, to confirm an excess or unhealthy distribution of body fat.</p> <p>We define two categories of obesity based on objective signs and symptoms of poor health due to excess body fat.</p> <p><strong>1. Clinical obesity</strong></p> <p>A person with clinical obesity has signs and symptoms of ongoing organ dysfunction and/or difficulty with day-to-day activities of daily living (such as bathing, going to the toilet or dressing).</p> <p>There are 18 diagnostic criteria for clinical obesity in adults and 13 in children and adolescents. These include:</p> <ul> <li> <p>breathlessness caused by the effect of obesity on the lungs</p> </li> <li> <p>obesity-induced heart failure</p> </li> <li> <p>raised blood pressure</p> </li> <li> <p>fatty liver disease</p> </li> <li> <p>abnormalities in bones and joints that limit movement in children.</p> </li> </ul> <p><strong>2. Pre-clinical obesity</strong></p> <p>A person with pre-clinical obesity has high levels of body fat that are not causing any illness.</p> <p>People with pre-clinical obesity do not have any evidence of reduced tissue or organ function due to obesity and can complete day-to-day activities unhindered.</p> <p>However, people with pre-clinical obesity are generally at higher risk of developing diseases such as heart disease, some cancers and type 2 diabetes.</p> <h2>What does this mean for obesity treatment?</h2> <p>Clinical obesity is a disease requiring access to effective health care.</p> <p>For those with clinical obesity, the focus of health care should be on improving the health problems caused by obesity. People should be offered evidence-based treatment options after discussion with their health-care practitioner.</p> <p><a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)01210-8/abstract">Treatment</a> will <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(22)00047-X/fulltext">include</a> management of obesity-associated complications and may include specific obesity treatment aiming at decreasing fat mass, such as:</p> <ul> <li> <p>support for <a href="https://www.obesityevidencehub.org.au/collections/treatment/behavioural-interventions-for-the-management-of-overweight-and-obesity-in-adults">behaviour change</a> <a href="https://www.obesityevidencehub.org.au/collections/treatment/managing-overweight-and-obesity-in-children-and-adolescents">around</a> diet, physical activity, sleep and screen use</p> </li> <li> <p>obesity-management medications to reduce appetite, lower weight and <a href="https://www.obesityevidencehub.org.au/collections/treatment/medication-and-surgery-for-the-treatment-of-overweight-and-obesity-in-adults">improve health</a> outcomes such as blood glucose (sugar) and blood pressure</p> </li> <li> <p>metabolic <a href="https://theconversation.com/thinking-about-bariatric-surgery-for-weight-loss-heres-what-to-consider-184153">bariatric surgery</a> to treat obesity or reduce weight-related health complications.</p> </li> </ul> <h2>Should pre-clinical obesity be treated?</h2> <p>For those with pre-clinical obesity, health care should be about risk-reduction and prevention of health problems related to obesity.</p> <p>This may require health counselling, including support for health behaviour change, and monitoring over time.</p> <p>Depending on the person’s individual risk – such as a family history of disease, level of body fat and changes over time – they may opt for one of the obesity treatments above.</p> <p>Distinguishing people who don’t have illness from those who already have ongoing illness will enable personalised approaches to obesity prevention, management and treatment with more appropriate and cost-effective allocation of resources.</p> <h2>What happens next?</h2> <p>These new criteria for the diagnosis of clinical obesity will need to be adopted into national and international clinical practice guidelines and a range of obesity strategies.</p> <p>Once adopted, training health professionals and health service managers, and educating the general public, will be vital.</p> <p>Reframing the narrative of obesity may help eradicate misconceptions that contribute to stigma, including making false assumptions about the health status of people in larger bodies. A better understanding of the biology and health effects of obesity should also mean people in larger bodies are not blamed for their condition.</p> <p>People with obesity or who have larger bodies should expect personalised, evidence-based assessments and advice, free of stigma and blame.<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/245164/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/louise-baur-5284"><em>Louise Baur</em></a><em>, Professor, Discipline of Child and Adolescent Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/john-b-dixon-11630">John B.

Some ancient Romans got to retire with a pension at 42, but retirement’s changed a bit over the centuries

<p><em><a href="https://theconversation.com/profiles/anthony-asher-247115">Anthony Asher</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Over the ages, there have been broadly three reasons why people have retired.</p> <p>Some are forced to by poor health – theirs or someone they care for. Others have alternative income sources, meaning they don’t rely on a regular pay cheque. And some are made to retire by an employer who wants to overhaul staffing.</p> <p>But where did the idea of retirement come from? And how was it handled in ancient times?</p> <h2>Origins of support</h2> <p>Retirement support – which these days comes in the form of superannuation or a government pension – dates back to ancient history in various forms.</p> <p>Some forms of retirement support were funded by local taxes or tithes, others by donations. Some systems were corrupt and the coverage was patchy.</p> <p>Records are not readily available from other cultures, but we know a little about ancient Rome and English history since then.</p> <p>Emperor Augustus, who ruled after Julius Caesar died, set up a <a href="https://pensionresearchcouncil.wharton.upenn.edu/wp-content/uploads/2020/01/03Chap3.pdf">scheme</a> for Roman soldiers more than 2,000 years ago. The scheme aimed to ensure they retired while still strong and healthy, and would be less likely to cause trouble.</p> <p>The scheme paid a decent amount for soldiers after 25 years of service, so retirement age could be as young as 42.</p> <p>Pensions for older people in need also have ancient origins. The New Testament <a href="https://biblehub.com/1_timothy/5-9.htm">Bible</a> records the churches had schemes for needy widows right from the beginning.</p> <p>In the early Middle Ages, monasteries often provided for the needy, but Henry VIII famously <a href="https://en.wikipedia.org/wiki/Dissolution_of_the_monasteries">closed them</a> and took their assets. A fair share of their assets ended up with <a href="https://en.wikipedia.org/wiki/John_Russell,_1st_Earl_of_Bedford">high government officials</a> after the king’s takeover.</p> <p>Industry funds can also be seen to date back <a href="https://www.britannica.com/money/friendly-society">at least to the Middle Ages</a>, where the trade guilds provided for members and their families who fell on hard times.</p> <p>Retail funds mainly began as <a href="https://www.google.com/search?client=firefox-b-d&q=history+of+life+insurance">mutual life insurance companies</a> that began more than 200 years ago.</p> <p>In the 18th century, the East India Company and the Bank of England began <a href="https://sas-space.sas.ac.uk/9224/1/McIlvenna%20PhD%20final.pdf">offering pensions</a>. These were at first discretionary based on need and loyalty, but later covered all employees. This idea then spread to other larger companies such railways and banks.</p> <p>As modern states developed the capacity to collect income taxes, it became feasible to provide comprehensive retirement benefits funded by central government.</p> <p>Beginning with <a href="https://www.ssa.gov/history/ottob.html">Germany in 1889</a>, developed countries began introducing universal national age pension arrangements.</p> <p>Unfortunately, a number of countries, such as <a href="https://www.uncdf.org/article/8799/governor-innovation-key-to-expanding-insurance-and-pension-coverage-in-png">Papua New Guinea</a>, still do not have the capacity to provide a universal safety net to cover older people.</p> <h2>Retirement in Australia</h2> <p>Three Australian states <a href="https://treasury.gov.au/publication/economic-roundup-centenary-edition-2001/article-3-towards-higher-retirement-incomes-for-australians-a-history-of-the-australian-retirement-income-system-since-federation">began schemes</a> in 1900, and the federal government provided a universal (but means tested) scheme from 1909.</p> <p>Most Australian retirees seem to enjoy a favourable standard of living. The <a href="https://grattan.edu.au/news/5-key-takeaways-from-the-retirement-income-review/">Grattan Institute</a> finds that the poorest 30% are, in fact, better off in retirement.</p> <p>Massive house price and rental inflation in the last 30 years, however, has gutted the living standards of those who don’t own their own homes. This gap in the safety net needs to be addressed.</p> <h2>Retirement ages</h2> <p>The Roman army model persists in some countries to this day: retirement from the US military is available <a href="https://sgp.fas.org/crs/misc/RL34751.pdf">after 20 years</a> of service.</p> <p>Retirement this early is obviously very expensive.

Woman cured of Type 1 diabetes in life-changing clinical trial

<p>Marlaina Goedel was diagnosed with Type 1 diabetes when she was just five-years-old, and not only was the disease controlling her, but it almost cost her life. </p> <p>"I've crashed my car into a brick building before having a diabetic attack while driving," Goedel recalled. </p> <p>Her condition was so extreme that she felt robbed of a normal childhood, telling the <em>Daily Mail </em>that she was in and out of hospital with life-threatening diabetic ketoacidosis, which causes toxic chemicals to build up in the blood due to a lack of insulin.</p> <p>Now 30-years-old, the Illinois woman no longer needs daily insulin shots and can finally enjoy sugar again thanks to a pioneering stem cell therapy that has cured her of type 1 diabetes. </p> <p>Goedel was one of three Americans who have been cured of their type 1 diabetes thanks to the clinical trial involving an islet cell transplant. </p> <p>It is a one-off infusion that involved transplanting islet cells into her liver to help her body produce insulin on its own. </p> <p>After four weeks, she no longer needed to take insulin. </p> <p>"[My doctor] said, ‘Mark it on your calendar. Today is the day. Stop all insulin,'" Goedel said of the life-changing moment. </p> <p>"I just went quiet and finally said, ‘I’m here. I’m in shock. I’m going to need you to repeat that.’"</p> <p>The trial was being run at the University of Chicago Medicine Transplant Institute. </p> <p>While Islet cell transplants isn't a new procedure, the current anti-rejection medication used can be toxic to the transplanted cells, potentially making it less effective over time. </p> <p>The clinical trial that ran at the university tested out a new antibody called tegoprubart, which was given to Goedel and the two other patients. </p> <p>Tegoprubart is made from lab-made antibodies that trick the immune system into thinking the body made the cells on its own, preventing them from being rejected. </p> <p>The patients were then given islet cells from a deceased donor's pancreas, which were then infused into the patient's small blood vessels in their liver. Those cells then lodged into the blood vessels and started producing insulin. </p> <p>For Goedel the only side effect of the procedure was "feeling like I got punched in the ribs," with the procedure lasting just an hour. </p> <p>"The cure is out there," Goedel told the <em>Daily Mail. </em></p> <p>With her new lease on life, Goedel plans to go back to school and go horse riding without worrying about suffering an attack and causing an accident. </p> <p>"It took a while to get used to saying, 'I am cured. I am diabetes free.' It's been very freeing," she said.</p> <p>"No one should have to live with this disease. I know that now more than ever."</p> <p><em>Images: Good Morning America/ UChicago Medicine</em></p> <p> </p>

Readers response: How do you handle changes in energy levels as you age?

<p>As we get older, our levels of energy, ability and agility can slowly start to decrease, making us change our day-to-day lifestyles. </p> <p>We asked our readers how they handle these changes, and the response was overwhelming. Here's what they said. </p> <p><strong>Margo Courtney</strong> - Eat clean and healthy and your body will reward you with heaps of energy and vitality. I have a very big green smoothie most days as one of my 2 meals, along with 2 litres of water a day, and I don't even need much sleep.</p> <p><strong>Ron Stubbs</strong> - Up at 8am, can’t be late for my walk in the sun, and feeling great. Don’t need afternoon snooze then. I’m 77.</p> <p><strong>Kristeen Bon</strong> - I don’t handle them. I flop on the couch most afternoons for a quick five minute interior eye check!</p> <p><strong>Sylvia Brice</strong> - I have an autoimmune disease so my levels of energy are way down. I do what l can in small bursts and rest when l need to. Luckily l read and craft so can always do them. It's very hard to adapt but that's life and l am so much better for off than younger people with my disease. Think positive.</p> <p><strong>Judie Fisher</strong> - Do chores in small stretches, and have regular breaks.</p> <p><strong>Diane Green</strong> - Adjust. I do what I can, and what I can't just has to wait.</p> <p><strong>Raymond Richards</strong> - As they told us at the heart clinic, if you have something you HAVE to do - do it first.</p> <p><strong>Janis St George</strong> - Listen to your body - rest awhile when you need to.</p> <p><strong>Kaylene Samuels</strong> - Have a SCAN.....

Eight simple changes to our neighbourhoods can help us age well

<p><em><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Where we live can play a big part in ageing well, largely because of the links between physical activity and wellbeing. <a href="https://www.ahuri.edu.au/__data/assets/pdf_file/0012/2181/AHURI_Final_Report_No214_Downsizing-amongst-older-Australians.pdf">Research shows</a> that two-thirds of Australians prefer to age in place. That is, we want to live independently in our homes for as long as we can. Our neighbourhoods and their design can then improve or hinder our ability to get out of the house and be physically active.</p> <p>The rapid ageing of Australia’s population only adds to the importance of neighbourhood design. In 2016, 15% of Australians were aged 65 or older. That proportion is <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/overview">projected to double</a> by 2056.</p> <p>These trends present several <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/reports">social and economic challenges</a>, particularly for the health sector. Designing neighbourhoods in ways that promote physical activity can help overcome these challenges.</p> <h2>Eight simple steps</h2> <p>The following is a short list of <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0471-5">evidence-based steps</a> local and state governments can take to assist older people to be physically active. These involve minor but effective changes to neighbourhood design.</p> <p><strong>Improve footpaths:</strong> Research indicates that older people have a <a href="https://theconversation.com/why-older-people-get-osteoporosis-and-have-falls-68145">higher risk of falls</a>. Ensuring footpaths are level and crack-free, and free from obstructions, will encourage walking among older people – especially those with a disability.</p> <p><strong>Connected pedestrian networks:</strong> Introducing footpaths at the end of no-through-roads and across long street blocks reduces walking distances to destinations. This makes walking a more viable option.</p> <p><strong>Slowing traffic in high-pedestrian areas:</strong> Slowing traffic <a href="https://www.heartfoundation.org.au/images/uploads/publications/Safe-Speed-Evidence-Report.pdf">improves safety</a> by reducing the risk of a collision. It also reduces the risk of <a href="https://www.ncbi.nlm.nih.gov/pubmed/28557669">death and serious injury</a> in the event of a collision.</p> <p><strong>Age-friendly street crossings:</strong> Installing longer pedestrian crossing light sequences gives older pedestrians <a href="https://academic.oup.com/ageing/article/41/5/690/47318/Most-older-pedestrians-are-unable-to-cross-the">more time to cross</a>, and installing refuge islands means those who walk more slowly can cross the street in two stages.</p> <p><strong>Disabled access at public transport:</strong> Although a form of motorised transport, public transport users undertake more incidental physical activity compared with car users. This is because they walk between transit stops and their origins and destinations. Improving disabled access helps make public transport a viable option for more older people.</p> <p><strong>Places to rest:</strong> <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/1471-2458-13-1054">Providing rest spots</a> such as benches enables older people to break up their walk and rest when needed.</p> <p><strong>Planting trees:</strong> Planting trees <a href="http://www.sciencedirect.com/science/article/pii/S0277953614004109?via%3Dihub">creates more pleasant scenery</a> to enjoy on a walk. It also provides shade on hot days.</p> <p><strong>Improving safety:</strong> Ensuring that streets are well-lit and reducing graffiti and signs of decay are likely to <a href="https://www.ncbi.nlm.nih.gov/pubmed/24552845">improve perceptions of safety</a> among older people.</p> <h2>Why physical activity matters</h2> <p>Physical function – the ability to undertake everyday activities such as walking, bathing and climbing stairs – often declines as people age.

Chaos erupts over last-minute cruise itinerary change

<p>Passengers onboard a Carnival Cruise have demanded refunds after their travel itinerary changed once they had already boarded the ship. </p> <p>Guests aboard Carnival’s Vista had booked the eight-night Southern Caribbean cruise out of Port Florida on August 10th intending to stop in Aruba, Curacao and Turks and Cacaos, with the eight-day cruise averaging $11,700 per person.</p> <p>However, as boarding was taking place, the cruise line sent passengers a notification saying their had been a change of plans due to an engine problem.</p> <p>Carnival crew members had discovered a “technical issue affecting the ship’s cruising speed” which forced the cruise line to alter the itinerary, the cruise line told the New York Post, with Vista instead traveling to the Bahamas, making stops at Nassau, Princess Cays, Freeport, and Half Moon Cay. </p> <p>While a cruise worker was trying to explain the situation to passengers, some started chanting "Give us our money!" while staff tried to diffuse the situation.</p> <blockquote class="instagram-media" style="background: #FFF;

Fighting for change: how much cash Olympic medallists actually win at Paris 2024

<p>As the world soaks up the glitz and glamour of Paris 2024, athletes are not just eyeing the podium – they're also thinking about the cash they might pocket. Or, in some cases, the cash they might not pocket. Because while the Olympics is a billion-dollar spectacle, the earnings for athletes can range from princely sums to pocket change.</p> <p><strong>Australia: A Gold Medal and a Discount Coupon</strong></p> <p>Let’s start with the Aussies. Winning gold at the Olympics might be the pinnacle of an athlete's career, but for Australian athletes, it also means... $20,000. Yes, you heard that right. In a land where a house deposit will likely cost you a LOT more, Aussie Olympians are basically getting paid in Monopoly money. Silver and bronze medalists get $15,000 and $10,000 respectively. That's enough for a decent holiday, but you might still need a GoFundMe for the flights.</p> <p><strong>Singapore: the million-dollar carrot</strong></p> <p>On the other end of the spectrum, athletes from Singapore are practically diving into pools of gold – like Scrooge McDuck, but in real life. A gold medal will earn them a staggering AU$1.13 million. That’s the kind of money that makes you forget about the gruelling four-year training cycle and instead think about which colour Lamborghini matches your national flag.</p> <p><strong>Hong Kong: fencing your way to riches</strong></p> <p>Hong Kong, not to be outdone, will reward its fencing champion Vivian Kong with AU$1.17 million for her gold. That’s enough to make you consider taking up fencing, even if you’re as coordinated as a baby giraffe.</p> <p><strong>Malaysia and Kazakhstan: cars and apartments</strong></p> <p>In Malaysia, winning athletes might not get cold hard cash, but they do get a new car. And in Kazakhstan, you can literally earn a place to call home – with more rooms depending on the colour of your medal. A gold gets you a penthouse, a silver a two-bedroom, and a bronze... well, maybe a studio with a view of the parking lot.</p> <p><strong>France: host with the most (ish)</strong></p> <p>The host nation, France, offers a more modest reward of $108,000 for a gold medal. That’s enough to cover a year's rent in Paris, or a really good wine collection. But let’s face it, in the land of fine dining, they might just spend it all on cheese.</p> <p><strong>New Zealand, Norway and the UK: the love of the game</strong></p> <p>Athletes from New Zealand, Norway and the UK? Well, they’ll have to make do with a pat on the back and a hearty “well done”, because there’s no financial incentive for winning a medal in these countries. Just the satisfaction of representing your nation, which, as any athlete will tell you, doesn't pay the bills.</p> <p><strong>The United States: the great divide</strong></p> <p>The US offers $37,500 for a gold medal, but that's chump change compared to the endorsement deals top athletes like swimmer Katie Ledecky pull in. She's reportedly earning $1 million a year from swimwear endorsements. Meanwhile, many other American athletes are scraping by, with some earning less than $15,000 a year. That's barely enough for a year's supply of Weet-Bix, let alone world-class training.</p> <p><strong>Jamaica: sharing the love</strong></p> <p>Jamaica’s Olympic team will share a pot of about AU$3,500 each, regardless of their results. It's the ultimate participation trophy – except it’s not enough to buy a trophy, or even a decent pair of running shoes.</p> <p><strong>World Athletics: the global jackpot</strong></p> <p>World Athletics is offering a $3.6 million prize pool for track and field events, with $76,000 per gold medalist. It's a model that some athletes, like Australia’s Arianne Titmus, think other sports should follow. After all, nothing says “thank you for your hard work” like a big, fat cheque.</p> <p>So, whether they’re racing for millions or just a modest thank you, athletes at Paris 2024 will be giving it their all. Because at the end of the day, it's not just about the money. It's about the glory, the honour, and ... well, okay, it’s mostly about the money.</p> <p><em>Images: Instagram \ Shutterstock</em></p>

Our obsession with taking photos is changing how we remember the past

<p><em><a href="https://theconversation.com/profiles/giuliana-mazzoni-175429">Giuliana Mazzoni</a>, <a href="https://theconversation.com/institutions/university-of-hull-1191">University of Hull</a></em></p> <p>I recently visited the <a href="http://hermitage--www.hermitagemuseum.org/wps/portal/hermitage/?lng=sv">Hermitage</a> in St Petersburg, Russia – one of the best art museums in the world. I was expecting to serenely experience its masterpieces, but my view was blocked by a wall of smart phones taking pictures of the paintings. And where I could find a bit of empty space, there were people taking selfies to create lasting memories of their visit.</p> <p>For many people, taking hundreds, if not thousands, of pictures is now a crucial part of going on holiday – documenting every last detail and posting it on social media. But how does that affect our actual memories of the past – and how we view ourselves? As an expert on memory, I was curious.</p> <p>Unfortunately, psychological research on the topic is so far scant. But we do know a few things. We use smart phones and new technologies <a href="http://studie-life.de/en/life-reports/smart-payments;%20https://www.researchgate.net/profile/Tim_Fawns/publication/275331048_Blended_Memory_the_Changing_Balance_of_Technologically-mediated_Semantic_and_Episodic_Memory/links/56962c6d08ae820ff07594ee.pdf">as memory repositories</a>. This is nothing new – humans have always used external devices as an aid when acquiring knowledge and remembering.</p> <p>Writing certainly serves this function. Historical records are collective external memories. Testimonies of migrations, settlement or battles help entire nations trace a lineage, a past and an identity. In the life of an individual, written diaries serve a similar function.</p> <h2>Memory effects</h2> <p>Nowadays we tend to commit very little to memory – we entrust a huge amount to the cloud. Not only is it almost unheard of to recite poems, even the most personal events are generally recorded on our cellphones. Rather than remembering what we ate at someone’s wedding, we scroll back to look at all the images we took of the food.</p> <p>This has serious consequences. Taking photos of an event rather than being immersed in it has been shown to lead to <a href="https://theconversation.com/memory-loss-isnt-just-an-old-persons-problem-heres-how-young-people-can-stay-mentally-fit-102352">poorer recall of the actual event</a> – we get distracted in the process.</p> <p>Relying on photos to remember has a similar effect. Memory needs to be exercised on a regular basis in order to function well. There are many studies documenting the importance of memory retrieval practice – <a href="http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.738.2035&rep=rep1&type=pdf">for example in university students</a>. Memory is and will remain essential for learning. There is indeed some evidence showing that committing almost all knowledge and memories to the cloud <a href="https://www.journals.uchicago.edu/doi/10.1086/691462">might hinder the ability to remember</a>.</p> <p>However, there is a silver lining. Even if some studies claim that all this makes us more stupid, what happens is actually shifting skills from purely being able to remember to being able to manage the way we remember more efficiently. This is called metacognition, and it is an overarching skill that is also essential for students – for example when planning what and how to study. There is also substantial and reliable evidence that external memories, selfies included, <a href="https://www.ncbi.nlm.nih.gov/pubmed/23957379">can help</a> individuals with memory impairments.</p> <p>But while photos can in some instances help people to remember, the quality of the memories may be limited. We may remember what something looked like more clearly, but this could be at the expense of other types of information. One study showed that while photos could help people remember what they saw during some event, they <a href="https://journals.sagepub.com/doi/abs/10.1177/0956797617694868">reduced their memory of what was said</a>.</p> <h2>Identity distortions?</h2> <p>There are some rather profound risks when it comes to personal memory. Our identity is a product of our life experiences, which can be easily accessed through our memories of the past. So, does constant photographic documentation of life experiences alter how we see ourselves? There is no substantial empirical evidence on this yet, but I would speculate that it does.</p> <p>Too many images are likely to make us remember the past in a fixed way – blocking other memories. While it is <a href="https://theconversation.com/what-is-your-first-memory-and-did-it-ever-really-happen-95953">not uncommon for early childhood memories</a> to be based on photos rather than the actual events, these are not always true memories.</p> <p>Another issue is the fact that research has uncovered <a href="https://www.sciencedirect.com/science/article/pii/S0747563216302503;%20http://www.vulture.com/2014/01/history-of-the-selfie.html">a lack of spontaneity in selfies</a> and many other photos. They are planned, the poses are not natural and at times the image of the person is distorted. They also reflect a narcissistic tendency which shapes the face in unnatural mimics – artificial big smiles, sensual pouts, funny faces or offensive gestures.</p> <p>Importantly, selfies and many other photos are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5318447/">public displays</a> of specific attitudes, intentions and stances. In other words, they do not really reflect who we are, they reflect what we want to show to others about ourselves at the moment. If we rely heavily on photos when remembering our past, we may create a distorted self identity based on the image we wanted to promote to others.</p> <p>That said, our natural memory isn’t actually perfectly accurate. Research shows that we often <a href="https://theconversation.com/the-real-you-is-a-myth-we-constantly-create-false-memories-to-achieve-the-identity-we-want-103253">create false memories about the past</a>. We do this in order to maintain the identity that we want to have over time – and avoid conflicting narratives about who we are. So if you have always been rather soft and kind – but through some significant life experience decide you are tough – you may dig up memories of being aggressive in the past or even completely make them up.</p> <p>Having multiple daily memory reports on the phone of how we were in the past might therefore render our memory less malleable and less adaptable to the changes brought about by life – making our identity more stable and fixed.</p> <p>But this can create problems if our present identity becomes different from our fixed, past one. That is an uncomfortable experience and exactly what the “normal” functioning of memory is aimed to avoid – it is malleable so that we can have a non-contradictory narrative about ourselves. We want to think of ourselves as having a certain unchanging “core”. If we feel unable to change how we see ourselves over time, this could seriously affect our sense of agency and mental health.</p> <p>So our obsession with taking photos may be causing both memory loss and uncomfortable identity discrepancies.</p> <p>It is interesting to think about how technology changes the way we behave and function. As long as we are aware of the risks, we can probably mitigate harmful effects. The possibility that actually sends shivers to my spine is that we lose all those precious pictures because of some widespread malfunctioning of our smart phones.</p> <p>So the next time you’re at a museum, do take a moment to look up and experience it all. Just in case those photos go missing.<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/109285/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-mazzoni-175429">Giuliana Mazzoni</a>, Professor of Psychology, <a href="https://theconversation.com/institutions/university-of-hull-1191">University of Hull</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How sustainable is your weekly grocery shop? These small changes can have big benefits

While a plant-based diet is <a href="https://www.nature.com/articles/s43016-023-00795-w">undeniably</a> good for the Earth, our <a href="https://www.sciencedirect.com/science/article/pii/S2352550924001945#f0025">new research</a> shows modest changes to your eating habits can also have significant environmental benefits.</p> <p>We assessed how food products on Australian supermarket shelves stack up against key environmental indicators, such as carbon emissions and water use.</p> <p>We found swapping the most environmentally harmful foods for more sustainable options within the same food group, such as switching from beef burgers to chicken burgers, can significantly reduce carbon emissions – by up to 96% in some instances.</p> <p>The last thing we want to do is take the pleasure away from eating. Instead, we want to help consumers make realistic dietary changes that also help ensure a sustainable future. So read on to find out which simple food swaps can best achieve this.</p> <h2>Informing sustainable diets</h2> <p>The environmental impact of foods can be estimated using an approach known as a <a href="https://www.cell.com/one-earth/fulltext/S2590-3322(19)30128-9#:%7E:text=In%20this%20Primer%2C%20we%20introduce,cycle%20of%20a%20product%20system.">life-cycle assessment</a>.</p> <p>This involves identifying the “inputs” required along the food supply chain, such as fertiliser, energy, water and land, and tracking them from farm to fork. From this we can calculate a product’s “footprint” – or environmental impact per kilogram of product – and compare it to other foods.</p> <p>Most studies of environmental footprints focus on the raw ingredients that make up food products (such as beef, wheat or rice) rather than the packaged products people see on shelves (such as beef sausages, pasta or rice crackers). Of the studies that do focus on packaged foods, most only consider a fraction of the products available to consumers.</p> <p>What’s more, a lot of research considers only the carbon emissions of food products, excluding other important measures such as water use. And some studies use global average environmental footprints, which <a href="https://www.science.org/doi/10.1126/science.aaq0216">vary significantly</a> between countries.</p> <p>Our research set out to overcome these limitations. We aligned environmental footprints with the products people find on supermarket shelves, and covered a huge range of food and beverage products available in Australia. We also included many environmental indicators, to allow a <a href="https://www.pnas.org/doi/full/10.1073/pnas.2120584119">more complete picture</a> of the sustainability of different foods.</p> <h2>What we did</h2> <p>Key to our research was the <a href="https://www.georgeinstitute.org.au/projects/foodswitch">FoodSwitch database</a>, which compiles food labelling and ingredient data from images of packaged food and beverages. It covers more than 90% of the Australian packaged food market.</p> <p>We combined the database with a <a href="https://www.sciencedirect.com/science/article/pii/S0959652623029748">mathematical method</a> that sums the environmental impact of ingredients, to quantify the footprint of the product as a whole.</p> <p>From this, we estimated the environmental footprint of 63,926 food products available in Australian supermarkets. We then simulated the potential benefits of making “realistic” switches between products – that is, switches within the same food category.</p> <h2>Our findings</h2> <p>The results show how making a small dietary change can have big environmental consequences.</p> <p>For a shopping basket composed of items from eight food groups, we simulate the benefits of swapping from high-impact towards medium- or low-impact food products.</p> <p>Our analysis assumes a starting point from the most environmentally harmful products in each food group – for example, sweet biscuits, cheese and beef burger patties.</p> <p>A shift to the medium-impact foods for all eight items – such as a muffin, yoghurt and sliced meat – can lead to at least a 62% reduction in environmental impact. Shifts towards the most sustainable choice for all items – bread, soy milk or raw poultry – can achieve a minimum 77% reduction.</p> <p>This analysis ends at the supermarket shelves and does not include additional food processing by the consumer. For example, raw meat will usually be cooked before human consumption, which will expand its environmental footprint to varying degrees, <a href="https://www.nature.com/articles/s43016-020-00200-w">depending on the method used</a>.</p> <p>See the below info-graphic for more detail.

Consumers need more information and support to choose more sustainable foods.</p> <p>Supermarkets and retailers also have an important role to play – for example, by giving sustainable products <a href="https://journals.sagepub.com/doi/10.1177/07439156211008898">prominent shelf placement</a>. Attractive pricing is also crucial – particularly in the midst of a <a href="https://theconversation.com/au/topics/cost-of-living-crisis-115238">cost-of-living crisis</a> when it can be difficult to prioritise sustainability over cost.</p> <p>Government interventions, such as information campaigns and <a href="https://journals.sagepub.com/doi/10.1177/07439156211008898">taxing high-impact products</a>, can also help.</p> <p>Food labelling is also important.

Are some routes more prone to air turbulence? Will climate change make it worse? Your questions answered

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/doug-drury-1277871">Doug Drury</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>A little bit of turbulence is a common experience for air travellers. Severe incidents are rare – but when they occur they can be deadly.</p> <p>The recent Singapore Airlines flight SQ321 from London to Singapore shows the danger. An <a href="https://apnews.com/article/singapore-airlines-flight-turbulence-5a9a268e1a6a6fb9ece7e58b5ea9231b">encounter with extreme turbulence</a> during normal flight left one person dead from a presumed heart attack and several others badly injured. The flight diverted to land in Bangkok so the severely injured passengers could receive hospital treatment.</p> <p>Air turbulence can happen anywhere, but is far more common on some routes than on others.</p> <p>Climate change is expected to boost the chances of air turbulence, and make it more intense. In fact, <a href="https://www.nature.com/articles/s41586-019-1465-z">some research</a> indicates turbulence <a href="https://theconversation.com/aviation-turbulence-soared-by-up-to-55-as-the-world-warmed-new-research-207574">has already worsened</a> over the past few decades.</p> <h2>Where does turbulence happen?</h2> <p>Nearly every flight experiences turbulence in one form or another.</p> <p>If an aircraft is taking off or landing behind another aircraft, the wind generated by the engine and <a href="https://www.faa.gov/air_traffic/publications/atpubs/aim_html/chap7_section_4.html">wingtips</a> of the lead aircraft can cause “wake turbulence” for the one behind.</p> <p>Close to ground level, there may be turbulence due to strong winds associated with weather patterns moving through the area near an airport. At higher altitudes, there may be wake turbulence again (if flying close to another aircraft), or turbulence due to updraughts or downdraughts from a thunderstorm.</p> <p>Another kind of turbulence that occurs at higher altitudes is harder to predict or avoid. So-called “<a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023gl103814">clear-air turbulence</a>” is invisible, as the name suggests. It is often caused by warmer air rising into cooler air, and is generally expected to get worse due to climate change.</p> <p>At the most basic level turbulence is the result of two or more wind events colliding and creating eddies, or swirls of <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">disrupted airflow</a>.</p> <p>It often occurs near mountain ranges, as wind flowing over the terrain accelerates upward.</p> <p>Turbulence also often occurs at the edges of the <a href="https://www.nationalgeographic.com/travel/article/what-is-turbulence-explained">jet streams</a>. These are narrow bands of strong, high-altitude winds circling the globe. Aircraft often travel in the jet streams to get a speed boost – but when entering or leaving the jet stream, there may be some turbulence as it crosses the boundary with the slower winds outside.</p> <h2>What are the most turbulent routes?</h2> <p>It is possible to <a href="https://turbli.com/maps/world-turbulence-map/">map turbulence patterns</a> over the whole world. Airlines use these maps to plan in advance for alternate airports or other essential contingencies.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&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/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=430&fit=crop&dpr=1 600w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=430&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=430&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=541&fit=crop&dpr=1 754w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=541&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/595676/original/file-20240522-21-ippmyt.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=541&fit=crop&dpr=3 2262w" alt="Map showing air turbulence." /></a><figcaption><span class="caption">A map of estimated clear-air turbulence around the world, current as of 3:00PM AEST (0500 UTC) on May 22 2024.</span> <span class="attribution"><a class="source" href="https://turbli.com/maps/world-turbulence-map/">Turbli</a></span></figcaption></figure> <p>While turbulence changes with weather conditions, some regions and routes are more prone to it than others.

Travel Trouble

How one widow has changed how women solo travel

<p>After Yvonne Vickers' husband passed away in 2014, she thought her opportunities to travel and see the world had slipped away. </p> <p>Yvonne had always been a keen traveller and went on trips with her married friends after becoming a widow, but she "got over being the third wheel", she admitted to <a href="https://travel.nine.com.au/latest/cruising-solo-female-older-passengers/9553953c-84e8-418a-9c2b-8c9b847b9ba4" target="_blank" rel="noopener"><em>9Travel</em></a>. </p> <p>Still wanting to see the world on her own terms, Yvonne took to Facebook where she created a group seeking like-minded women who share her passion for adventure. </p> <p>Now, the Find A Female Cruise or Travel Buddy is an ever-growing group that has connected thousands of women looking for travel companions. </p> <p>Whether they're single, widowed, or just married to someone who doesn't want to travel, the group is open to women across the globe to join.</p> <p>Thanks to her newfound community, Yvonne has taken 41 cruises and dozens of land trips since her husband's death, all while making friends for life, and the rest of the group's members are in the same boat.</p> <p>"It's wonderful to get feedback from ladies saying that it's helped to change their life," Yvonne said. "That's the rewarding part of it for me."</p> <p>Members can make a post in the group, detailing a cruise sailing or trip that they have their eye on booking, to see if anyone else would like to join them.</p> <p>"We have a lot of widows in our group who are cashed up and want to travel but don't have anyone to travel with or share their experiences with," Yvonne said. "The group gives them the opportunity to be able to do that."</p> <p>"There are also a lot of ladies who are married but their husbands don't want to travel. It gives them the opportunity to be able to travel."</p> <p>Yvonne says that cruising is a perfect way for older females to travel, especially if they're on their own.</p> <p>"It's a really safe way to travel as a solo female," she says, also noting that it's an easy way to get around and see places. Recently, she did a 35-day trip around Hawaii with a group of women from the group.</p> <p>For the Find A Female Cruise or Travel Buddy group, there's even more fun trips on the horizon.</p> <p>Yvonne just came back from a trip to Japan with 14 group members, and is heading to Bali in August with a friend she made through the group.</p> <p><em>Image credits: Nine News \ Facebook</em></p>

The season kicked off with the arrival of Norwegian Bliss on April 3 — the <a href="https://www.cheknews.ca/first-cruise-ship-of-the-season-to-arrive-in-victoria-in-less-than-2-weeks-1196426/">first of 318 ships</a> that are scheduled to dock in Victoria this year. Victoria saw a record 970,000 passengers arrive in 2023, with more expected in 2024.</p> <p>The cruise industry <a href="https://doi.org/10.1016/j.trip.2021.100391">was badly hit</a> by the <a href="https://financialpost.com/financial-times/the-2020s-were-meant-to-be-a-boom-decade-for-cruises-then-covid-19-hit-them-like-a-tidal-wave">suspension of cruise operations due to the COVID-19 pandemic</a> in 2020. Fuelled by heavy consumer demand and industry innovation, cruising has made a comeback. It is now one of the fastest-growing sectors, rebounding even faster than international tourism.</p> <p>While many predicted <a href="https://www.cnbc.com/2020/04/05/carnivals-struggle-to-survive-the-coronavirus-as-outbreak-wipes-out-the-cruise-industry.html">a difficult recovery</a>, a <a href="https://cruising.org/en">recent industry report shows a remarkable post-pandemic rebound</a>. Two million more people went on cruises in 2023 versus 2019, with demand predicted to top 35 million in 2024.</p> <p>But environmental issues plague the sector’s revival. Are they an indication of rough seas ahead? Or will a responsive industry mean smooth sailing?</p> <p>Cruising has long been criticized <a href="https://www.sbs.com.au/news/article/their-purpose-is-to-be-fun-but-theres-a-dark-side-to-cruising-the-seas/dzxivdoos">for being Janus-faced</a>: on the surface, cruises are convenient, exciting holidays with reputed economic benefits. But lurking underneath are its <a href="https://doi.org/10.1016/j.tourman.2017.11.002">negative environmental and social impacts</a>.</p> <h2>Unprecedented growth</h2> <p>Newly constructed mega-ships are part of the industry’s unprecedented growth.

To entice first-timers and meet the needs of repeat cruisers, companies are offering new itineraries and onboard activities, from <a href="https://www.timescolonist.com/business/royal-caribbean-quantum-cruise-ship-1st-at-sea-bumper-cars-skydiving-observation-capsule-4585987">simulated skydiving and bumper cars</a> to <a href="https://nationalpost.com/travel/cruise-ship-offers-pickleball-on-the-high-seas">pickleball</a> and lawn bowling.</p> <p>Solo cruise travel is also on the rise, and <a href="https://www.cruisetradenews.com/demand-for-multi-generational-cruise-holidays-on-the-up-data-finds/">multi-generational family cruise travel</a> is flourishing, explaining the extensive variety of cabin classes, activities and restaurants available on newly constructed and retrofitted ships.</p> <p>However, only a few cruise ports are large enough to dock mega ships. Cruise lines are responding by offering off-beat experiences and catering more to the distinct desires of travellers.</p> <p>In doing so, there is a <a href="https://www.positivelyosceola.com/2024s-top-cruise-trends-embracing-smaller-ships-solo-adventures-and-luxury-suites/">move towards smaller vessels and luxury liners</a>, river cruises and <a href="https://www.travelweek.ca/news/cruise/expedition-cruising-what-is-it-and-how-do-you-sell-it/">expedition cruising</a>.

How music is changing the way dementia patients think

<p dir="ltr">New research has proven that music truly is the universal language, with experts discovering how the power of music is helping those suffering with dementia. </p> <p dir="ltr">Music therapists have shown that music brings dementia patients back to the present, with some even finding their voice thanks to the nostalgic memories of the past. </p> <p dir="ltr">According to Registered Music Therapist and Managing Director of music therapy company Music Beat, Dr Vicky Abad, the power of music is not to be overlooked when it comes to degenerative diseases.</p> <p dir="ltr">“Music is a window into people’s pasts,” she said. “It builds on strengths and abilities against a disease that can strip a person of their dignity, abilities and quality of life.”</p> <p dir="ltr">The team at <a href="https://www.tricare.com.au/">TriCare Aged Care and Retirement</a>, who see the devastating impact of dementia each and every day, also experience first-hand the impact music has on residents, with many noticing “unrecognisable” changes in personality when a nostalgic tune is played.</p> <p dir="ltr">Louis Rose, an 80-year-old dementia patient and TriCare resident, was diagnosed with dementia six years ago, and requires assistance with many aspects of day to day life. </p> <p dir="ltr">However, listening to music is one thing he can enjoy on his own.</p> <p dir="ltr">“I grew up in Mauritius and while we didn’t have a lot, we certainly had music. Listening to music has always been an escape for me and a way to relax,” Mr Rose said.</p> <p dir="ltr">“When your brain starts to slow down and you find yourself forgetting things, it can be quite frustrating and confusing. Listening to music has been a way to distract myself from what’s going on in my head, it has helped me so much.”</p> <p dir="ltr">Tamsin Sutherland is a regular live music performer at TriCare facilities across Queensland, and has been able to witness incredible moments with the residents as they come alive as soon as she starts to play. </p> <p dir="ltr">“Watching residents who are often non-verbal sing along to the words is incredible,” she said “It really is like they are coming back to life and reconnecting with who they once were. To be part of that is quite emotional for me.”</p> <p dir="ltr">According to Dr Abad, music can help prevent the restless behaviour that often leads to pacing and wandering, especially in the evenings, which are often difficult times for those battling the disease. </p> <p dir="ltr">“Sundowning usually occurs in the late afternoon as dusk approaches, a time that is also associated with what used to be a busy time period in people’s lives,” she noted. </p> <p dir="ltr">“Personalised music is a simple and effective tool to help residents feel validated in their emotions during this time and provides them an opportunity to experience a calmer state of mind”.</p> <p dir="ltr"><em>Image credits: Getty Images </em></p>

King Charles makes historic change to Balmoral

<p>King Charles has made a historic change to Balmoral for the first time ever, allowing the public for an exclusive look inside the royal residence. </p> <p>Later this year, the King will allow public tours of the Scottish castle, with small group tours available to be led by expert royal guides. </p> <p>Those being shown around the royal residence will get a unique glimpse in several rooms used by the King and Queen.</p> <p>A source close to the royal family said the initiative was in line with the King's wish to make royal residences more accessible to the public.</p> <p>It also reflects Charles' comments made after Queen Elizabeth's death, that the house had been earmarked as a place for the public to remember her.</p> <p>While Balmoral holds a lot of historical importance, the Scottish residence is not set up to handle a large influx of tourists. </p> <p>As a result, a month-long tour programme to begin in July will serve as a trial period to see how the castle and staff copes with increased footfall.</p> <p>Until now, the interior of the vast castle has largely remained out of bounds to members of the public, with tours limited to just the ballroom, the grounds and the gardens.</p> <p>The Balmoral estate announced the tours on Tuesday on its <a href="https://www.balmoralcastle.com" target="_blank" rel="noopener">website</a>, stating, "For the first time since the castle was completed in 1855, we have been granted permission to take you on a private tour with our experienced guides."</p> <p>"They will take you on a historical journey through several of the beautiful rooms within Balmoral Castle. You will learn about the origins of the Castle and how it has been loved by generations of the Royal family."</p> <p>"You will see why Balmoral is such a special place - the much loved and celebrated Highland home of the Royal family."</p> <p>Only forty tickets each day will be sold for the "castle interior tour" for £100 ($193 AUD), or £150 ($289 AUD) if afternoon tea is included.</p> <p>The tours will take place from July 1st until August 4th, before the King and Queen arrive for their annual break. </p> <p>The season begins later this year due to the refurbishment of the restaurant but if successful, the opening hours will likely be extended in the future.</p> <p><em>Image credits: Getty Images </em></p>

Why our voices change as we get older

<p><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>Sir Elton John set a record at this year’s Glastonbury, becoming the <a href="https://www.independent.co.uk/arts-entertainment/music/news/elton-john-glastonbury-viewing-record-b2364260.html">most-watched headliner</a> in the festival’s history, with more than 7 million people tuning in live to the BBC to watch his last ever UK performance.</p> <p>The 76-year-old singer certainly delivered all his characteristic showmanship. But many who have followed his music over the decades will have noticed how much his voice has changed during his career – and not only because of the <a href="https://www.billboard.com/music/music-news/a-qa-with-elton-john-65620/">surgery he had</a> in the 1980s to <a href="https://ultimateclassicrock.com/elton-john-throat-surgery/">remove polyps</a> from his vocal cords.</p> <p>Equally, it’s not all down to the process of ageing. While it’s no mystery that this affects every part of our body, it isn’t the only reason that a person’s voice – even a professional singer like Sir Elton – can sound quite different over the years.</p> <h2>The sound of your voice</h2> <p>The vocal cords are what produce the sound of your voice. They are located in the <a href="https://www.ncbi.nlm.nih.gov/books/NBK538202/">larynx</a>, a part of the respiratory system that allows air to pass from your throat to your lungs. When air passes out of the lungs and through the larynx, it causes the vocal cords to vibrate – <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5412481/">producing sound</a>.</p> <p>The vocal cords are composed of <a href="https://www.kenhub.com/en/library/anatomy/vocal-cords">three main parts</a>: the vocalis muscle, vocal ligament, and a mucous membrane (containing glands) to cover them. This keeps the surface moist and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2810851/">protects them from damage</a>.</p> <p>There are also approximately <a href="https://radiopaedia.org/articles/intrinsic-muscles-of-the-larynx?lang=gb">17 other muscles</a> in the larynx that can alter vocal cord position and tension – thus changing the sound produced.</p> <p>Pre-puberty, there’s very little difference in the sound the vocal cords produce. But during puberty, hormones begin exerting their effects. This changes the structure of the larynx – making the “Adam’s apple” more prominent in men – and the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0018506X16301271?via%3Dihub">length of the vocal cords</a>. After puberty, they’re around 16mm in length in men, and 10mm in women.</p> <p>Women’s vocal cords are also <a href="https://pubs.aip.org/asa/jasa/article/82/S1/S90/719336/Physiology-of-the-female-larynx">20-30%</a> thinner after puberty. These shorter, thinner vocal cords are the reason why women typically have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3306615">higher voices</a> than men.</p> <p>Even after puberty, hormones can affect the voice. For instance, a woman’s voice may sound different depending on the stage of her menstrual cycle – with the <a href="https://www.jvoice.org/article/S0892-1997(08)00169-0/fulltext">best voice quality</a> being in the ovulatory phase. This is because the glands produce most mucous during this phase, giving the vocal cords their best functional ability.</p> <p>Research also shows that women taking the contraceptive pill show <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199717304940">less variation in voice quality</a> because the pill halts ovulation.</p> <p>On the other hand, hormonal changes during the premenstrual phase impede the vocal cords, making them stiffer. This may explain why opera singers would be offered “<a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199717301133">grace days</a>” in the 1960s to ensure they didn’t damage their vocal cords. And, because <a href="https://www.asha.org/practice-portal/clinical-topics/voice-disorders/#collapse_1">women’s vocal cords</a> are thinner, they may also be more likely to <a href="https://pubmed.ncbi.nlm.nih.gov/15157130/">suffer damage</a> from overuse.</p> <h2>Everything ages</h2> <p>As with almost every other part of the body, vocal cords age. But these changes might not be as <a href="https://www.sciencedirect.com/science/article/pii/S0892199721000011">noticeable for everyone</a>.</p> <p>As we get older, the larynx begins increasing its <a href="https://www.sciencedirect.com/science/article/abs/pii/S1752928X21001840">mineral content</a>, making it stiffer and more like bone than cartilage. This change can begin happening as early as <a href="https://meridian.allenpress.com/angle-orthodontist/article/75/2/196/57743/Ossification-of-Laryngeal-Cartilages-on-Lateral">your thirties</a> – especially in men. This makes the vocal cords less flexible.</p> <p>The muscles that allow the vocal cords to move also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6166195/">begin wasting</a> (as do our other muscles) as we age. The ligaments and tissues that support the vocal cords also <a href="https://pubmed.ncbi.nlm.nih.gov/11800365/">lose elasticity</a>, becoming <a href="https://pubmed.ncbi.nlm.nih.gov/25645525/">less flexible</a>.</p> <p>There’s also a decrease in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2695176/">pulmonary muscle function</a>, reducing the power of the air expelled from the lungs to create the sound. The number of glands that produce the protective mucus also decrease, alongside a reduction in the ability to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10156980/">control the larynx</a>.</p> <h2>Lifestyle is a factor</h2> <p>While vocal cords age at largely the same rate in most people, many lifestyle factors can increase the risk of damage to them – and so can change the way your voice sounds.</p> <p>Smoking, for example, causes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3918293/">localised inflammation</a>, increased <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4824943/">mucous production</a>, but can also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4557797/">dry out</a> the mucosal surfaces. Alcohol has a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6166195/">similar effect</a>. Over time, these factors can damage the vocal cords and alter the voice’s sound.</p> <p>Some over-the-counter and prescription drugs can also alter the voice – such as <a href="https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/482932">steroid inhalers used for laryngitis</a>. Blood thinners may also <a href="https://pubmed.ncbi.nlm.nih.gov/10875579/">damage the vocal cords</a> and can cause polyps to form, making the voice sound raspy or hoarse. <a href="https://pubmed.ncbi.nlm.nih.gov/7395839/">Muscle relaxants</a>, too, can lead to irritation and vocal cord damage due to the drug allowing stomach acid to wash back into the larynx. Thankfully, the irritation and changes caused by these medications typically disappears after stopping use.</p> <p>One other lifestyle factor can be overuse, which is typically seen in singers and other people who use their voice a lot <a href="https://pubmed.ncbi.nlm.nih.gov/15157130/">during work</a>, such as teachers and fitness instructors. This can lead to an uncommon condition called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9392404/">Reinke’s oedema</a>, which can also be caused by smoking. Reinke’s oedema causes fluid to swell in the vocal cords, changing the pitch of the voice – often <a href="https://www.cuh.nhs.uk/patient-information/reinkes-oedema/">making it deeper</a>.</p> <p>In extreme cases of Reinke’s oedema, <a href="https://link.springer.com/article/10.1007/s00405-022-07377-9">surgery is needed</a> to drain the fluid. But in most cases, rest and avoiding irritants (smoking and alcohol) is beneficial, while speech and language therapy can also address the <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1460-6984.1995.tb01660.x">change in sound</a>.</p> <h2>Maintaining our vocal quality</h2> <p>While we can’t help some of the age-related changes that happen to our vocal cords, we can maintain some of our vocal quality and ability through continued use. This may explain why, in many cases, singers show <a href="https://pubmed.ncbi.nlm.nih.gov/27049451/">significantly less vocal change</a> with age than their non-singing counterparts.</p> <p>Singing or <a href="https://www.aarp.org/health/healthy-living/info-2014/improve-aging-voice.html">reading out</a> loud daily can give the vocal cords sufficient exercise to slow their decline.</p> <p><a href="https://www.nidcd.nih.gov/health/taking-care-your-voice">Looking after</a> your vocal cords is also important. Staying hydrated and limiting intake of <a href="https://www.cuh.nhs.uk/patient-information/presbyphonia/">alcohol</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7069957/">tobacco</a> can help prevent high rates of decline and damage.<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/208640/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/adam-taylor-283950"><em>Adam Taylor</em></a><em>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Out of the rabbit hole: new research shows people can change their minds about conspiracy theories

<p><em><a href="https://theconversation.com/profiles/matt-williams-666794">Matt Williams</a>, <a href="https://theconversation.com/institutions/massey-university-806">Massey University</a>; <a href="https://theconversation.com/profiles/john-kerr-1073102">John Kerr</a>, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a>, and <a href="https://theconversation.com/profiles/mathew-marques-14884">Mathew Marques</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a></em></p> <p>Many people <a href="https://theconversation.com/was-phar-lap-killed-by-gangsters-new-research-shows-which-conspiracies-people-believe-in-and-why-158610">believe at least one</a> conspiracy theory. And that isn’t necessarily a bad thing – conspiracies <em>do</em> happen.</p> <p>To take just one example, the CIA really did engage in <a href="https://www.politico.com/story/2019/04/13/cia-mind-control-1266649">illegal experiments</a> in the 1950s to identify drugs and procedures that might produce confessions from captured spies.</p> <p>However, many conspiracy theories are not supported by evidence, yet still attract believers.</p> <p>For example, in a <a href="https://doi.org/10.1111/pops.12746">previous study</a>, we found about 7% of New Zealanders and Australians agreed with the theory that <a href="https://www.earthdata.nasa.gov/learn/sensing-our-planet/on-the-trail-of-contrails">visible trails behind aircraft</a> are “chemtrails” of chemical agents sprayed as part of a secret government program. That’s despite the theory being <a href="https://iopscience.iop.org/article/10.1088/1748-9326/11/8/084011">roundly rejected</a> by the scientific community.</p> <p>The fact that conspiracy theories attract believers despite a lack of credible evidence remains a puzzle for researchers in psychology and other academic disciplines.</p> <p>Indeed, there has been a great deal of research on conspiracy theories published in the past few years. We now know more about how many people believe them, as well as the psychological and political factors that <a href="https://www.nature.com/articles/s41598-022-25617-0">correlate with that belief</a>.</p> <p>But we know much less about how often people change their minds. Do they do so frequently, or do they to stick tenaciously to their beliefs, regardless of what evidence they come across?</p> <h2>From 9/11 to COVID</h2> <p>We set out to answer this question using a <a href="https://doi.org/10.1038/s41598-024-51653-z">longitudinal survey</a>. We recruited 498 Australians and New Zealanders (using the <a href="http://prolific.com">Prolific</a> website, which recruits people to take part in paid research).</p> <p>Each month from March to September 2021, we presented our sample group with a survey, including ten conspiracy theories, and asked them how much they agreed with each one.</p> <p>All of these theories related to claims about events that are either ongoing, or occurred this millennium: the September 11 attacks, the rollout of 5G telecommunications technology, and COVID-19, among others.</p> <p>While there were definitely some believers in our sample, most participants disagreed with each of the theories.</p> <p>The most popular theory was that “pharmaceutical companies (‘Big Pharma’) have suppressed a cure for cancer to protect their profits”. Some 18% of the sample group agreed when first asked.</p> <p>The least popular was the theory that “COVID-19 ‘vaccines’ contain microchips to monitor and control people”. Only 2% agreed.</p> <h2>Conspiracy beliefs probably aren’t increasing</h2> <p>Despite contemporary concerns about a “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7320252/">pandemic of misinformation</a>” or “<a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30461-X/fulltext">infodemic</a>”, we found no evidence that individual beliefs in conspiracy theories increased on average over time.</p> <p>This was despite our data collection happening during the tumultuous second year of the COVID-19 pandemic. Lockdowns were still happening occasionally in both <a href="https://www.timeout.com/melbourne/things-to-do/a-timeline-of-covid-19-in-australia-two-years-on">Australia</a> and <a href="https://covid19.govt.nz/about-our-covid-19-response/history-of-the-covid-19-alert-system/">New Zealand</a>, and anti-government sentiment was building.</p> <p>While we only tracked participants for six months, <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0270429">other studies</a> over much longer time frames have also found little evidence that beliefs in conspiracy theories are increasing over time.</p> <hr /> <p><iframe class="flourish-embed-iframe" style="width: 100%; height: 600px;" title="Interactive or visual content" src="https://flo.uri.sh/visualisation/16665395/embed" width="100%" height="400" frameborder="0" scrolling="no" sandbox="allow-same-origin allow-forms allow-scripts allow-downloads allow-popups allow-popups-to-escape-sandbox allow-top-navigation-by-user-activation"></iframe></p> <div style="width: 100%!; margin-top: 4px!important; text-align: right!important;"><a class="flourish-credit" href="https://public.flourish.studio/visualisation/16665395/?utm_source=embed&utm_campaign=visualisation/16665395" target="_top"><img src="https://public.flourish.studio/resources/made_with_flourish.svg" alt="Made with Flourish" /></a></div> <hr /> <p>Finally, we found that beliefs (or non-beliefs) in conspiracy theories were stable – but not completely fixed. For any given theory, the vast majority of participants were “consistent sceptics” – not agreeing with the theory at any point.</p> <p>There were also some “consistent believers” who agreed at every point in the survey they responded to. For most theories, this was the second-largest group.</p> <p>Yet for every conspiracy theory, there was also a small proportion of converts. They disagreed with the theory at the start of the study, but agreed with it by the end. There was also a small proportion of “apostates” who agreed with the theory at the start, but disagreed by the end.</p> <p>Nevertheless, the percentages of converts and apostates tended to balance each other pretty closely, leaving the percentage of believers fairly stable over time.</p> <h2>Inside the ‘rabbit hole’</h2> <p>This relative stability is interesting, because <a href="https://www.jstor.org/stable/2564659">one criticism</a> of conspiracy theories is that they may not be “<a href="https://www.britannica.com/topic/criterion-of-falsifiability">falsifiable</a>”: what seems like evidence against a conspiracy theory can just be written off by believers as part of the cover up.</p> <p>Yet people clearly <em>do</em> sometimes decide to reject conspiracy theories they previously believed.</p> <p>Our findings bring into question the popular notion of the “rabbit hole” – that people rapidly develop beliefs in a succession of conspiracy theories, much as Alice tumbles down into Wonderland in Lewis Carroll’s <a href="https://www.gutenberg.org/ebooks/11">famous story</a>.</p> <p>While it’s possible this does happen for a small number of people, our results suggest it isn’t a typical experience.</p> <p>For most, the <a href="https://www.latrobe.edu.au/news/articles/2023/opinion/how-to-talk-to-someone-about-conspiracy-theories">journey into</a> conspiracy theory belief might involve a more gradual slope – a bit like a <a href="https://zslpublications.onlinelibrary.wiley.com/doi/pdfdirect/10.1111/j.1469-7998.1985.tb05649.x">real rabbit burrow</a>, from which one can also emerge.</p> <hr /> <p><em>Mathew Ling (<a href="https://www.neaminational.org.au/">Neami National</a>), Stephen Hill (Massey University) and Edward Clarke (Philipps-Universität Marburg) contributed to the research referred to in this article.</em><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/222507/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <hr /> <p><em><a href="https://theconversation.com/profiles/matt-williams-666794">Matt Williams</a>, Senior Lecturer in Psychology, <a href="https://theconversation.com/institutions/massey-university-806">Massey University</a>; <a href="https://theconversation.com/profiles/john-kerr-1073102">John Kerr</a>, Senior Research Fellow, <a href="https://theconversation.com/institutions/university-of-otago-1304">University of Otago</a>, and <a href="https://theconversation.com/profiles/mathew-marques-14884">Mathew Marques</a>, Senior Lecturer in Social Psychology, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
