Is stress turning my hair grey?

<p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>When we start to go grey depends a lot on <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">genetics</a>.</p> <p>Your first grey hairs <a href="https://elifesciences.org/articles/67437">usually appear</a> anywhere between your twenties and fifties. For men, grey hairs <a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">normally</a> start at the temples and sideburns. Women tend to start greying on the hairline, especially at the front.</p> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">rapid greying</a> usually happens between ages 50 and 60. But does anything we do speed up the process? And is there anything we can do to slow it down?</p> <p>You’ve probably heard that plucking, dyeing and stress can make your hair go grey – and that redheads don’t. Here’s what the science says.</p> <h2>What gives hair its colour?</h2> <p>Each strand of hair is produced by a hair follicle, a tunnel-like opening in your skin. Follicles contain two different kinds of <a href="https://www.sciencedirect.com/science/article/pii/S1534580720301040">stem cells</a>:</p> <ul> <li>keratinocytes, which produce <a href="https://my.clevelandclinic.org/health/body/23204-keratin">keratin</a>, the protein that makes and regenerates hair strands</li> <li>melanocytes, which produce <a href="https://my.clevelandclinic.org/health/body/22615-melanin">melanin</a>, the pigment that colours your hair and skin.</li> </ul> <p>There are <a href="https://www.ncbi.nlm.nih.gov/books/NBK459156/">two main types</a> of melanin that <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">determine hair colour</a>. Eumelanin is a black-brown pigment and pheomelanin is a red-yellow pigment.</p> <p>The <a href="https://theconversation.com/studying-the-complex-genetics-behind-hair-colour-reveals-how-melanin-affects-us-171088#:%7E:text=Eumelanin%20is%20also%20known%20as%20the%20brown-black%20pigment%2C,is%20due%20to%20low%20amounts%20of%20both%20pigments.">amount of the different pigments</a> determines hair colour. Black and brown hair has mostly eumelanin, red hair has the most pheomelanin, and blonde hair has just a small amount of both.</p> <h2>So what makes our hair turn grey?</h2> <p>As we age, it’s normal for cells to become less active. In the hair follicle, this means stem cells produce less melanin – turning our hair grey – and less keratin, causing hair thinning and loss.</p> <p>As less melanin is produced, there is less pigment to give the hair its colour. Grey hair has very little melanin, while white hair has none left.</p> <p>Unpigmented hair <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">looks grey</a>, white or silver because light reflects off the keratin, which is pale yellow.</p> <p>Grey hair is thicker, coarser and stiffer than hair with pigment. This is because the shape of the hair follicle becomes <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">irregular</a> as the stem cells change with age.</p> <p>Interestingly, grey hair also grows faster than pigmented hair, but it <a href="https://elifesciences.org/articles/67437">uses more energy</a> in the process.</p> <h2>Can stress turn our hair grey?</h2> <p>Yes, stress can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">cause your hair to turn grey</a>. This happens when <a href="https://faseb.onlinelibrary.wiley.com/doi/epdf/10.1096/fj.05-4039fje">oxidative stress</a> damages hair follicles and stem cells and <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2022.839859/full">stops them producing</a> melanin.</p> <p>Oxidative stress is an imbalance of too many damaging free radical chemicals and not enough protective antioxidant chemicals in the body. It can be <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">caused by</a> psychological or emotional stress as well as autoimmune diseases.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22077870/">Environmental factors</a> such as exposure to UV and pollution, as well as smoking and some drugs, can also play a role.</p> <p>Melanocytes are <a href="https://elifesciences.org/articles/67437">more susceptible to damage</a> than keratinocytes because of the complex steps in melanin production. This explains why ageing and stress usually cause hair greying before hair loss.</p> <p>Scientists have been able to link less pigmented sections of a hair strand to <a href="https://elifesciences.org/articles/67437">stressful events in a person’s life</a>. In younger people, whose stems cells still produced melanin, colour returned to the hair after the stressful event passed.</p> <h2>4 popular ideas about grey hair – and what science says</h2> <p><strong>1. Does plucking a grey hair make more grow back in its place?</strong></p> <p>No. When you pluck a hair, you might notice a small bulb at the end that was attached to your scalp. This is the <a href="https://my.clevelandclinic.org/health/body/23435-hair-follicle">root</a>. It grows from the hair follicle.</p> <p>Plucking a hair pulls the root out of the follicle. But the follicle itself is the opening in your skin and can’t be plucked out. Each hair follicle can only grow a single hair.</p> <p>It’s possible frequent plucking could make your hair <a href="https://pubmed.ncbi.nlm.nih.gov/18713071/">grey earlier</a>, if the cells that produce melanin are damaged or exhausted from too much regrowth.</p> <p><strong>2. Can my hair can turn grey overnight?</strong></p> <p>Legend says Marie Antoinette’s hair went <a href="https://www.healthline.com/health/marie-antoinette-syndrome">completely white</a> the night before the French queen faced the guillotine – but this is a myth.</p> <p>Melanin in hair strands is chemically stable, meaning it can’t transform instantly.</p> <p>Acute psychological stress does rapidly deplete melanocyte stem cells <a href="https://www.nature.com/articles/s41586-020-1935-3">in mice</a>. But the effect doesn’t show up immediately. Instead, grey hair becomes visible as the strand grows – at a rate of <a href="https://www.medicalnewstoday.com/articles/326764">about 1 cm per month</a>.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7432488/">Not all hair</a> is in the growing phase at any one time, meaning it can’t all go grey at the same time.</p> <p><strong>3. Will dyeing make my hair go grey faster?</strong></p> <p>This <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9953601/">depends on the dye</a>.</p> <p>Temporary and semi-permanent dyes should not cause early greying because they just coat the hair strand without changing its structure. But permanent products cause a chemical reaction with the hair, using an oxidising agent such as hydrogen peroxide.</p> <p>Accumulation of hydrogen peroxide and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10232955/">other hair dye chemicals</a> in the hair follicle <a href="https://pubmed.ncbi.nlm.nih.gov/36631178/">can damage</a> melanocytes and keratinocytes, which can cause greying and hair loss.</p> <p><strong>4. Is it true redheads don’t go grey?</strong></p> <p>People with red hair also lose melanin as they age, but differently to those with black or brown hair.</p> <p>This is because the red-yellow and black-brown pigments are chemically different.</p> <p>Producing the brown-black pigment eumelanin is more complex and <a href="https://onlinelibrary.wiley.com/doi/full/10.1034/j.1600-0749.2002.02017.x">takes more energy</a>, making it more susceptible to damage.</p> <p>Producing the red-yellow pigment (pheomelanin) causes <a href="https://www.sciencedirect.com/science/article/pii/S016953472030375X">less oxidative stress</a>, and is more simple. This means it is easier for stem cells to continue to produce pheomelanin, even as they reduce their activity with ageing.</p> <p>With ageing, red hair tends to fade into strawberry blonde and silvery-white. Grey colour is due to less eumelanin activity, so is more common in those with black and brown hair.</p> <p>Your genetics determine when you’ll start going grey. But you may be able to avoid premature greying by staying healthy, reducing stress and avoiding smoking, too much alcohol and UV exposure.</p> <p>Eating <a href="https://www.healthline.com/health/melanin-in-hair#b-6-and-b-12">a healthy diet</a> may also help because vitamin B12, copper, iron, calcium and zinc all <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6290285/">influence melanin production and hair pigmentation</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/239100/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate Professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</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.

Embrace grey hair with our simple healthy hair tips

<p>While in the past going grey may have been seen as a negative of the ageing process, today women are embracing this as a stamp of wisdom. And why not? It’s en vogue and can look really attractive too. Thank goodness the days of “having” to hide your natural colour are gone! But just because you’re going natural, doesn’t mean there’s no effort involved. Knowing how to care for and style your grey locks is key and can make all the difference between “stylish and sixty-plus” and “stuffy and sixty-plus”. Read on for our top tips and tricks for healthy, happy hair.</p> <p><strong>Focus on your cut</strong> – A great cut is essential for any hair colour but especially for grey hair. Chances are good that you may have been dyeing your hair in the months/years leading up to embracing grey… so a decent chop may increase the health and vitality of your locks. Speak to your hairdresser about a style that suits both your face shape and lifestyle.</p> <p><strong>Swap your shampoo</strong> – Grey hair is far more prone to breakage and can also become quite dry and coarse. Ensuring that you’re using a moisturising shampoo at every wash can help keep strands in good condition.</p> <p><strong>Condition well</strong> – If you’ve been wary of conditioner in the past due to your hair being on the oily side, now is the time to become friendly again. Conditioning with a moisturising formula is essential after every shampoo. If you’re still nervous about hair becoming oily, you can try a shampoo for “normal” hair, which will nourish without weighing hair down.</p> <p><strong>Treat yourself to an at-home treatment</strong> – Once a fortnight, treat your hair with a shampoo specifically formulated for grey hair. After washing and conditioning, apply a clear colour glaze or gloss which is designed to coat the cuticle, boosting shine and general vitality.</p> <p><strong>Take care when styling</strong> – As it’s prone to dryness and breakage, applying a thermal protectant to your hair before heat styling is a great way to prevent damage from occurring. Simply comb through hair and style as normal. It’s also a good idea to try and have a day or two off a week from using your hairdryer/hot implements to give hair a good break.</p> <p><em>Images: Getty</em></p>

10 best tips for gracefully growing out grey hair

<h2>Pro tips that make going grey so much better</h2> <p>There’s no avoiding it. At some point, you will have to deal with grey hair. Of course, how you deal with it is up to you. Some women start growing out grey hair as soon as it begins to appear. Others begin their journey by pulling out greys and then spend years dyeing it before deciding it’s too much of a hassle to do the constant cover-up. Even if you’ve found the <a href="https://www.readersdigest.com.au/healthsmart/beauty/how-to-find-the-best-hair-colour-for-your-skin-tone" target="_blank" rel="noopener">best hair colour for your skin tone</a>, having to touch up your roots every four to six weeks can get old. No matter what your path is, going grey isn’t for the faint of heart.</p> <p>“Many women find it challenging to grow out grey hair,” says hairstylist Krysta Biancone. “This is because it usually occurs gradually, so the transition from natural hair colour to grey hair is not easy.”</p> <p>But it’s not all doom and gloom when it comes to going grey. In fact, it can be incredibly empowering, liberating and downright gorgeous when you make it to the finish line, and it can even make you look younger. But first, there are a few things you need to know. We asked top hairstylists around the country to divulge their best tips for making this transition as easy as possible.</p> <h2>Add highlights</h2> <p>It might sound counterintuitive, but adding subtle colour can make the transition to grey more seamless. “When you first decide you’re nearly ready to go natural, a step in the right direction would be to start going lighter. That way, the roots grow in a little more gracefully,” says hair stylist and colourist, Kali Ferrara. “This can be done easily by a skilled colourist, with a lighter base colour in conjunction with highlights.”</p> <p>One word of warning: steer clear of warmer colours like reds and strawberry blondes when growing out grey hair. Ferrara says these hues could backfire and show even more contrast with your roots.</p> <h2>Go a little darker</h2> <p>On the flip side, you could choose lowlights. But instead of adding a shade that’s slightly darker (which is normally what you’d do with lowlights), try to match your non-grey hair colour. This will help blend without adding a brand-new shade to the mix. “Lowlights create some contrast and will give hair a more salt-and-pepper look that can be very becoming,” says celebrity hairstylist Gina Rivera. Just be sure not to go darker than your hair colour, says Rivera. Doing so can create too much contrast and bring more attention to the fact that you are transitioning to grey, which won’t look good in photos or in real life.</p> <h2>Chop it off</h2> <p>Ready for a big change? Ferrara recommends growing your roots as long as you possibly can and then getting a super-short haircut to get rid of all the leftover colour. How short you go is totally up to you. A pixie cut can be chic and low-maintenance, but if you’ve never had short hair, that could be too big of a change. A short bob looks good on just about anyone, so that may be your best bet, though a stylist will be able to help you determine just how short will be flattering for your face shape. In general, slimmer faces tend to look great with hair that hits just under the jawbone, while fuller faces may want to go slightly longer (think a few centimetres below the jaw).</p> <p>“While this can be a dramatic change, it can also be just the new look you may be looking for!” Ferrara says. “Think of your natural hair colour as a new adventure – a new, liberated you.”</p> <h2>Cover roots as they grow in</h2> <p>If you’re growing out grey hair but your roots are driving you nuts, there are a few ways you can hide them. One easy solution is to cover them with a headband, hat or chic scarf. Another option is root spray or powder. “These products can mask the roots very effectively,” says master stylist Lorrene Conino. “Just spray the exposed areas after you style your hair.”</p> <p>Just shake the bottle well, hold it about 15 centimetres from your roots and spritz it on. These products offer instant coverage on grey hair without an expensive trip to the salon.</p> <h2>Don’t slack on trims</h2> <p>If you can’t bring yourself to do a big cut, regular haircuts (even little ones!) can help make the process go faster too. Aim for a trim every six to eight weeks. This will help you get rid of split ends and maintain healthy hair during your growing-out period, says hairstylist Nia Jones. After all, she explains, you may as well keep your hair looking as good as possible as you go through this tricky transition. Another bonus? Even if you aren’t getting a drastic cut, snipping a bit each time will get rid of old colour.</p> <h2>Prevent brassiness</h2> <p>As more and more grey starts growing in, make sure those strands look as good as possible. Although grey hair is less vibrant than hair of other colours, it still can become dull and uneven if not properly cared for. Sun exposure, washing hair with water that has a high mineral content, and improper hair care are just a few reasons grey locks can turn brassy. Luckily, there’s a quick fix: using shampoo and conditioner designed specifically for silver or white hair can help tone down brassiness by balancing out the warm undertones, says Biancone.</p> <p>You can also include purple toning products into your maintenance routine. Why purple? To understand how a purple product works, you need to know a bit about colour theory. Essentially, on the colour wheel, purple is opposite of yellow. This means that purple shampoo or toner helps to neutralise unwanted yellow or brassy tones that can come along with greys. Try adding toning drops to your shampoo or conditioner once a week to keep your hair the colour you want it. Taking this small precaution when caring for grey hair can help create luscious-looking locks with longevity.</p> <h2>Go big on moisture</h2> <p>The texture of grey hair is quite different from the hair of your youth. George Papanikolas, a celebrity hairstylist, explains that it’s typically more coarse, frizzy and dehydrated. To combat this, he recommends arming your strands with moisturising products that will keep it silky and shiny.</p> <h2>Don’t try to remove hair dye on your own</h2> <p>Let’s say you’ve been dying your hair to cover up those greys but wish you hadn’t. Well, even if you’ve just been using root touch-up kits as new greys grow in, you should never try to lift or remove hair dye on your own. “Chemicals are typically used to remove colour, and you need to know what you are doing,” warns Rivera. “If you don’t, you could end up really damaging your hair.” If this is a route you’re intent on exploring instead of waiting for the colour to grow out, book an appointment with a professional. Just be aware that removing hair dye is tricky and often takes multiple appointments.</p> <p>For an easier, much gentler option, try using a clarifying shampoo to lighten the dye on your strands, says Jones. These shampoos are formulated to remove excess buildup and give you a deep clean, but they may also help wash away some colour. Just don’t use them more than once a week. These products give hair a deep clean, and using them too often can strip your strands of natural oils that add hydration.</p> <h2>Experiment with new styles</h2> <p>Whether you’re trying to cover up the grey or want to embrace it, Jones suggests playing with different styles outside of the boundaries of your everyday look – ie, a ponytail, a different part that flatters your face shape or a brushed-back style that ‘hides’ roots. Changing things up allows you to play with your style, and it also makes growing out grey hair look cool and intentional. Who says blondes have all the fun?!</p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/beauty/10-best-tips-for-gracefully-growing-out-grey-hair" target="_blank" rel="noopener">Reader's Digest</a>.</em></p> <p><em>Images: Getty</em></p>

Unlocking the Silver Revolution: The Truth About Grey Hair and the Empowering Journey to Embrace the Grey

<p>In a recent poll by midlife connection organisation, Connected Women reveals that two-thirds of women over the age of 50 haven’t embraced their grey hair (67%). With hair starting to go grey in our 30s and 40s, that’s a long time to hide those pesky greys!</p> <p><strong>What causes grey hair? </strong></p> <p>According to Harvard Health, hair doesn’t ‘turn’ grey. Once a strand of hair is a particular colour, it will stay that way unless it is dyed. After the age of 35, hair follicles produce less colour, so when that strand of hair falls out it will be more likely to grow back grey.</p> <p><strong>Can stress cause grey hair? </strong></p> <p>There is very little evidence to indicate that this is true, however, research shows that in mice, in response to a fight or flight situation, hair follicles are impacted and the pigmentation-producing stem cells can be lost. Without stem cells available to produce pigment cells, the hair will go grey.</p> <p>So, can we now legitimately blame our grey hairs on our kids, or our husbands.</p> <p><strong>What happens when you pluck your grey hairs out? </strong></p> <p>Don’t do it! Not only will it simply grow back grey, but according to Trey Gillen, hairstylist and creative director of education at SACHAJUAN, doing so can also traumatise the follicles which could mean NO hair grows back.</p> <p><strong>When is the right time to go grey?</strong></p> <p>This is something that only you can decide. If your hair is dark brown or black, your greys will be more noticeable, so you’ll need to have regular (two to four weekly) trips to the hairdresser to cover them up. At some point you will most likely grow weary of trying to stem the tide and it will be time to just embrace the grey. You will know when you’ve had enough!</p> <p>If you have lighter hair, then your greys will be much less noticeable. Lighter hair gives you a much longer window between coloring appointments in the initial stages of going grey, and later you can use the greys as ‘herringbone highlights’ as per Sarah Jessica Parker’s beautiful mane, which is wonderful way to gracefully embrace going grey.</p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2023/05/Phoebe-headshot-EDITED.jpg" alt="" width="1280" height="720" /></p> <p><span style="box-sizing: border-box; font-weight: bolder; color: #212529; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 16px; background-color: #ffffff;"><span style="box-sizing: border-box; caret-color: #212529;"><em style="box-sizing: border-box;">Phoebe Adams is the founder of Connected Women, an organisation providing a community for women over 50 to connect with each other and build meaningful friendships.

Explainer: Why does hair turn grey?

<p>For many people, grey hair is a fact of life. It’s a sign that we are getting older and that our bodies are going through change. </p> <p>To understand why hair turns grey, we first need to understand why it has colour in the first place. The answer is a special type of cell known as a melanocyte. These produce melanin, the pigment that gives your skin, hair and eyes their distinctive colours.</p> <p>Melanin comes in two forms, eumelanin (black or brown) and pheomelanin (reddish-yellow). Combinations of these two create the spectrum of eye, hair and skin colours found among humans.</p> <p>One way to understand how melanocytes determine hair colour is to think of these cells as tiny printers, applying their ink to paper. The paper in this case is our hair strands, formed of keratin, the same protein that makes up our fingernails.</p> <p>Just as a printer sprays ink onto a sheet of paper to produce an image, melanocytes produce pigments that are embedded into the growing hair strand, providing them with colour. The melanocytes live within the hair follicle, so each hair strand has its own colour-producing printer.</p> <p>While some people’s melanocytes print a lighter ink combination, such as blonde or red, others have darker colour palletes and so have black or brown colourations.</p> <p>Now that we understand how hair gets its colour, we can understand why it goes grey.</p> <p>In hair, grey is not a colouration like any other shade: it is the lack of colouring. The keratin of people with grey hair lacks pigment because their melanocytes have died, revealing the natural grey-white colour of the keratin protein.</p> <p>Because each hair strand has its own melanocytes, some go grey before others. Exactly what decides which strands go grey first is still unknown. However, age, exposure to chemicals and even the climate can influence how early the melanocytes die.</p> <p>The strongest influence, however, is written in our genes. The genetic influence on hair colour is so strong that if your parents have grey hair, yours is likely to grey at around the same time as theirs did.</p> <p><em>Image credits: Getty Images</em></p> <p><em><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=19408&amp;title=Explainer%3A+Why+does+hair+turn+grey%3F" width="1" height="1" /></em></p> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/science/biology/explainer-why-does-hair-turn-grey/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Jake Port. </em></p> </div>

As countries ranging from Indonesia to Mexico aim to attract digital nomads, locals say ‘not so fast’

<p>Should your community welcome <a href="https://www.merriam-webster.com/dictionary/digital%20nomad">digital nomads</a> – individuals who work remotely, allowing them freedom to bounce from country to country?</p> <p><a href="https://global.oup.com/academic/product/digital-nomads-9780190931780?cc=us&amp;lang=en&amp;">Our research</a> has found that workers are eager to embrace the flexibility of not being tied to an office. And after experiencing economic losses due to the COVID-19 pandemic, cities and countries are concocting ways to entice visitors.</p> <p>One idea involves stretching the meaning of tourism to include remote workers.</p> <p>Today, a growing number of countries offer so-called “<a href="https://nomadgirl.co/countries-with-digital-nomad-visas/">digital nomad visas</a>.” These visas allow longer stays for remote workers and provide clarity about allowable work activities. For example, officials in Bali, Indonesia, are looking to formalize a process for remote workers to procure visas – “<a href="https://coconuts.co/bali/features/the-faster-the-better-bali-tourism-agency-head-tjokorda-bagus-pemayun-talks-digital-nomad-visa-plans-and-what-it-means-for-the-island/">the faster, the better</a>,” as the head of the island’s tourism agency put it.</p> <p>Yet pushback from locals in cities ranging <a href="https://time.com/6072062/barcelona-tourism-residents-covid/">from Barcelona</a> to <a href="https://nypost.com/2022/07/28/mexico-city-residents-angered-by-influx-of-americans-speaking-english-gentrifying-area-report/">Mexico City</a> has made it clear that there are costs and benefits to an influx of remote workers. </p> <p>As we explain in our new book, “Digital Nomads: In Search of Freedom, Community, and Meaningful Work in the New Economy,” the trend of “work tourism” <a href="https://global.oup.com/academic/product/digital-nomads-9780190931780?cc=us&amp;lang=en&amp;">comes with a host of drawbacks</a>.</p> <h2>Wearing out their welcome</h2> <p>For as long as there’s been tourism, locals have griped about the outsiders who come and go. These travelers are usually a welcome boost to the economy – <a href="https://dictionary.cambridge.org/us/dictionary/english/overtourism">up to a point</a>. They can also wear out their welcome. </p> <p>Perhaps the classic example is <a href="https://www.bloomberg.com/news/articles/2021-06-25/venice-reinventing-itself-as-sustainable-tourism-capital">Venice</a>, where high numbers of tourists stress the canal-filled city’s fragile infrastructure.</p> <p>In the U.S., New Jersey shore residents have long used the term “<a href="https://en.wikipedia.org/wiki/Shoobie">shoobies</a>” to denigrate the annual throng of short-term summer tourists. In our research on digital nomads in Bali, locals referred to digital nomads and other tourists as “bules” – a word that roughly translates as “foreigners.”</p> <p>Generally the terms are used to express minor annoyance over crowds and increased traffic. But conventional tourists come and go – their stays usually range from a couple of nights to a couple of weeks. Remote workers stay anywhere from weeks to months – or longer. They spend more time using places and resources traditionally dedicated to the local residents. This raises the chances that outsiders become a grating presence. </p> <p>Excessive numbers of visitors can also raise sustainability concerns, as waves of tourists tax the environment and infrastructure of many destinations. Many of Bali’s beautiful rice fields and surrounding lush forests, for example, are being converted into hotels and villas to serve tourism.</p> <h2>Digital nomads look to stretch their dollars</h2> <p>Whether they’re lazing around or plugging away on their laptops, privileged tourists ultimately change the economics and demographics of an area. </p> <p>Their buying power increases costs and displaces residents, while traditional businesses make way for ones that cater to their tastes. <a href="https://theconversation.com/how-food-became-the-perfect-beachhead-for-gentrification-167761">Where once there was a neighborhood food stand</a>, now there’s an upscale cafe. </p> <p>This dynamic is only exacerbated by long-term tourists. Services like VRBO and Airbnb make it easy for digital nomads to rent apartments for weeks or months at a time, and <a href="https://www.bbc.com/news/business-45083954">people around the world are increasingly alarmed</a> at how quickly such rentals can change the affordability and character of a place.</p> <p>Living a vacation lifestyle on a long-term basis implies a need to choose lower-cost destinations. This means that remote workers may particularly contribute to gentrification as they seek out places where their dollars go furthest.</p> <p>In <a href="https://travelnoire.com/digital-nomads-see-why-mexicans-are-fed-up-with-them">Mexico City</a>, residents fear displacement by remote workers able to pay higher rents. In response to calls to choose Mexico City as a remote working destination, one local succinctly expressed opposition: “<a href="https://www.vox.com/the-goods/22999722/mexico-city-pandemic-remote-work-gentrification">Please don’t</a>.”</p> <p>And in <a href="https://www.theguardian.com/us-news/2019/mar/13/new-orleans-airbnb-treme-short-term-rentals">New Orleans</a>, almost half of all properties in the historic <a href="https://nola.curbed.com/2018/5/16/17356630/treme-new-orleans-neighborhood-history-pictures">Tremé district</a> – one of the oldest Black neighborhoods in the U.S. – have been converted to short-term rentals, displacing longtime residents.</p> <h2>Culture becomes commodified</h2> <p><a href="https://suitcasemag.com/articles/neocolonial-tourism">Neocolonialism</a> in tourism refers to the way processes such as overtourism and gentrification create a power imbalance that favors newcomers and erodes local ways of life. </p> <p>“There’s a distinction between people who want to learn about the place they are in and those who just like it because it’s cheap,” one digital nomad living in Mexico City <a href="https://www.latimes.com/world-nation/story/2022-07-27/americans-are-flooding-mexico-city-some-mexicans-want-them-to-go-home">recently told the Los Angeles Times</a>. “I’ve met a number of people who don’t really care that they’re in Mexico, they just care that it’s cheap.”</p> <p>Bali, where <a href="https://www.aseantoday.com/2020/10/balis-economy-struggles-to-survive-without-tourists/">as much as 80%</a> of the island’s economy is estimated to be affected by tourism, offers a stark example. </p> <p>People come to Bali to be immersed in the culture’s spiritual rituals, art, nature and dance. But there’s also resentment over yoga lovers, resortgoers and digital nomads “taking over” the island. And some locals come to see the tourism in and around temples and rituals as the transformation of something cherished – the nuanced and spiritual aspects of their culture – into experiences to be bought and sold. </p> <p>For instance, Balinese dance performances are huge tourist draws and are even featured in global promotions for tourism on the island. Yet these performances also have cultural and spiritual meaning, and the impact of tourism on these aspects of dance is <a href="https://www.researchgate.net/publication/37628994_Authenticity_and_commodification_of_Balinese_dance_performances">debated even among performers</a>.</p> <p>So there is inevitably friction, which can be seen in the high levels of <a href="https://coconuts.co/bali/features/living-in-a-petty-crimes-paradise-balis-unreported-thefts-and-muggings/">petty crime</a>against foreigners. Neocolonialism can also pit people from the same country or culture against one another. For example, <a href="https://www.travelmole.com/news/bali-taxi-wars-flare-again/">conflicts arise</a> between local Balinese taxi cooperatives and taxi services that employ drivers from other parts of Indonesia. </p> <p>Although remote employees still make up a small portion of the overall tourist population, their work-related needs and longer stays mean they’re more likely to use services and places frequented by locals.</p> <p>Whether this leads digital nomads to be welcomed or scorned likely depends on both government policies and tourists’ behavior. </p> <p>Will governments take measures such as protecting locals from mass evictions, or will landlords’ desire for higher rents prevail? Will guests live lightly and blend in, trying to learn the local language and culture? Or will they simply focus on working hard and playing harder? </p> <p>As remote work reaches an unprecedented scale, the answers to such questions may determine whether “<a href="https://coconuts.co/bali/features/the-faster-the-better-bali-tourism-agency-head-tjokorda-bagus-pemayun-talks-digital-nomad-visa-plans-and-what-it-means-for-the-island/">the faster, the better</a>” attitude toward digital nomad visas and other incentives continues.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/as-countries-ranging-from-indonesia-to-mexico-aim-to-attract-digital-nomads-locals-say-not-so-fast-189283" target="_blank" rel="noopener">The Conversation</a>.</em></p>

Veteran newsreader reportedly fired for "going grey"

<p>A veteran newsreader has reportedly been fired from one of Canada’s most-watched television news programs after "going grey". </p> <p>Lisa LaFlamme announced she would be leaving the CTV National News presenter said she was “blindsided” and left “shocked and saddened” by the allegedly sudden decision to end her contract.</p> <p>“At 58, I still thought I’d have a lot more time to tell more of the stories that impact our daily lives,” she said in the Twitter video.</p> <p>“It is crushing to be leaving CTV National News in a manner that is not my choice.”</p> <p>The news anchor said she was asked to keep the details of her termination confidential, as the company released a statement saying the decision had nothing to do with LaFlamme’s hair colour or age and was simply “a business decision”.</p> <p>LaFlamme, like many people around the world, stopped dying her previously brown hair throughout the pandemic, a decision she told viewers she wished she had made sooner.</p> <p>“I finally said, ‘Why bother? I’m going grey.’ Honestly, if I had known the lockdown could be so liberating on that front I would have done it a lot sooner,” she said during the network’s year-in-review special.</p> <p>LaFlamme has been in the anchor job since 2011 but has been with the news outlet for 35 years, and still had two years left on her contract at the time of the “blindside”.</p> <p>Bell Media, which owns CTV National News, said it knew many viewers would be disappointed LaFlamme “would be leaving her position”, and regretted the way the news had been revealed.</p> <p>It added it would launch an independent investigation into newsroom practices.</p> <p>“CTV regrets that the way in which the news of her departure has been communicated may have left viewers with the wrong impression about how CTV regards Lisa and her remarkable career,” Bell Media tweeted in a statement.</p> <p>“We have always taken matters regarding any discrimination very seriously and are committed to a safe, inclusive and respectful work environment for all our employees, devoid of any toxic behaviour."</p> <p>“Consistent with our policies, we are taking steps to initiate an independent third-party internal workplace review of our newsroom, which will take place over the following weeks.”</p> <p><em>Image credits: CTV News</em></p>

For the love of Greys – retiree volunteers and retired ex-racers

<p>It’s an unexpected match made in heaven, but retirees hoping to give their time to a good cause could find one in a four-legged friend looking for a home.</p> <p>With National Volunteer Week (16 – 22 May 2022) soon upon us, it’s timely to recognise all volunteers. But there’s a very special group of retirees who go the extra mile for Greyhounds.</p> <p>Contrary to popular belief, Greyhounds are big goofy sooks and will swamp you with adoration and love. They’ll also adopt a place on your couch or bed as a loyal pet. This is why many volunteers and foster carers not only adopt a grey or two, but also actively want to save them from greyhound racing.</p> <p>Not surprisingly, the RSPCA <a href="https://kb.rspca.org.au/knowledge-base/what-are-the-animal-welfare-issues-with-greyhound-racing/#what-needs-to-change" target="_blank" rel="noopener">does not support greyhound racing</a> due to the many unresolved animal welfare concerns associated with the so-called sport. These concerns motivate rescue groups, as well as activists.</p> <p>CPG (the Coalition for the Protection of Greyhounds) is a dedicated group of volunteers across Australia who work together to inform the public about the cruelties of dog racing – <a href="http://www.facebook.com/CoalitionForTheProtectionOfGreyhounds" target="_blank" rel="noopener">FB</a>,<a href="http://www.greyhoundcoalition.com/" target="_blank" rel="noopener"> </a><a href="http://www.greyhoundcoalition.com/" target="_blank" rel="noopener">web</a>,<a href="https://www.instagram.com/coalitionprotectgreyhounds/" target="_blank" rel="noopener"> </a><a href="https://www.instagram.com/coalitionprotectgreyhounds/" target="_blank" rel="noopener">Insta</a>,<a href="http://www.greyhoundcoalition.com/cpg-in-the-media" target="_blank" rel="noopener"> </a><a href="http://www.greyhoundcoalition.com/cpg-in-the-media" target="_blank" rel="noopener">media coverage</a></p> <p>Retired nurse Annie is one of CPG’s amazingly enthusiastic volunteers. She’s a media spokesperson for the group and is often busy doing radio and newspaper interviews. Her love affair with Greyhounds started long ago.</p> <p>“I saw an ad on Facebook by Gumtree Greys for foster carers, applied and was introduced to Holly. This beautiful black greyhound girl had been an Irish Champion and ‘Bitch of the year’ in 2012. She was bought by an Australian syndicate at two years old and kept to breed from,” said Annie.</p> <p>Holly whelped many litters until she was nine years old and had her last puppies by caesarean. When Annie took Holly to be desexed, the vet said she was a mess inside and had been sewn up with nylon non-dissolving sutures.</p> <p>“Holly taught me all about how gentle, quirky, dorky, loving and unintentionally hilarious greyhounds are, like the way their jaws quiver when they are happy. All of my future foster greyhounds learnt how to become great pets with guidance from gorgeous Holly,” said Annie.</p> <p>“I foster greyhounds because they deserve the chance of a good life as a dog and pet, not just a product or commodity. Greyhounds bring me so much joy. In return, I speak out for them because of what they suffer on Australia’s many racing tracks.”</p> <p>Annie says she’s appalled by the fact that in 2021, there were <a href="https://greyhoundcoalition.com/2021-australian-track-deaths-and-injuries/" target="_blank" rel="noopener">212 greyhound deaths</a> on Australian dog tracks and over 10,000 injuries, according to statistics from official stewards’ reports. Because of this, she volunteers for CPG and other greyhound-related voluntary bodies. She’s also a motorbike enthusiast and uses her motorbike riding to raise money for greyhound welfare.</p> <p>Alicia – one of CPG’s newest volunteers – is semi-retired. She works part-time in journalism and interior design, but adores Greyhounds. Her male black Greyhound, Fluffy, is now nearly seven years old and has been retired from racing for four years.</p> <p>“Fluffy is one of the lucky survivors from the greyhound racing tracks, as he only won one race and is loving his retired life on the couch! He’s a soppy sook despite his size and the name suits him down to the ground as he is not an Anubis or Nero by nature,” said Alicia.</p> <p>“My lovely boy is very nervous due to his past racing days. He’s frightened of loud noises such as cars or motorbikes, as well as thunder and lightning. He absolutely loves children and babies, as he instinctively knows they won’t harm him.”</p> <p>She says greyhounds are ideal companions for retirees as they are lazy couch potatoes, love cuddles, are very affectionate and generally don’t need more than one walk of 20 minutes a day.</p> <p>“I volunteer with CPG by writing content for publication. They really need more people who have at least five years’ experience writing news releases and placing them with media outlets. Greyhounds are innocents with no voice, so we speak up for them,” said Alicia.</p> <p>She said CPG’s <a href="https://greyhoundcoalition.com/5-key-demands/" target="_blank" rel="noopener">five-point plan</a> is aimed at reforming the racing industry. As well as increased penalties for mistreatment, the plan includes tracking each dog from birth to death so they don’t ‘disappear’, reduced breeding, sanctuaries and safer tracks.</p> <p>Fran, previously a lecturer in Environmental Science, is spokesperson and leader of the Tasmanian activist group <a href="https://www.facebook.com/Let-Greyhounds-Run-Free-425546354301519/?ref=page_internal" target="_blank" rel="noopener">Let Greyhounds Run Free</a> (LGRF), which formed as a result of the ABC's Four Corners program on live baiting and the subsequent Parliamentary Inquiry into the Tasmanian Greyhound Industry. LGRF has held several rallies against greyhound racing, and continues to lobby for the end of this cruel, archaic industry. </p> <p>Fran began her greyhound journey back in 2000 when she came across a Greyhound Adoption stall at a local event. She was instantly hooked after meeting a few of these four-legged beauties and adopted the timid and scared Miss Ruby. It was Ruby who introduced Fran to the dark life of a racing greyhound. </p> <p>Ruby was soon joined by regal Jena. Ruby was terrified, and Jena was injured and a severe epileptic - why we may never know, and it was then that Fran vowed she would do whatever she could to end greyhound racing.</p> <p>All these years later, having had the joy of six hounds and several more foster hounds, she now has the privilege of living with Paddy and Jennifer Jane.</p> <p>Paddy became well known in promotions for Let Greyhounds Run Free's rallies. He is also a champion at helping timid and shy foster greyhounds come back to life after their traumas, and adjust to life as it should be, in a safe and loving home. </p> <p>“I have stories about all the beauties who have blessed my life. They are the most gentle, loving, soul-filled, quirky beings and I'm so very grateful I met ‘Miss Ruby Two Shoes’ way back then in 2000” says Fran. </p> <p>Meanwhile, retired lawyer Jeff is also a tireless campaigner, volunteer and lover of greyhounds. He’s been a supporter of the worldwide campaign to end greyhound racing for the last 15 years or so.</p> <p>“When my pet greyhound died in 2015, I promised myself to continue fighting for the cause. That was the year when the live baiting scandal broke in Australia,” he said.</p> <p>“I followed the news reports and the inquiries closely. When an opportunity arose to become an admin at the new Facebook group ‘<a href="https://www.facebook.com/groups/1376102522706650/" target="_blank" rel="noopener">Ban Greyhound Racing – Australia Wide</a>’, it was an ideal way to support the growing anti-racing campaign.”</p> <p>Jeff said the group’s focus has always been on activism.</p> <p>“There are many other social media outlets where people can share pictures of their rescued greyhounds and discuss their care, behaviour and feeding. On our page, we try to be a resource for current information about the Australian racing industry.”</p> <p>Those interested in adopting or fostering a goofy hound, should contact one of the groups listed <a href="https://greyhoundcoalition.com/links-to-greyhound-rescue-groups/" target="_blank" rel="noopener">here</a>, while anyone interested in volunteering with CPG, can find out more <a href="https://greyhoundcoalition.com/volunteering-with-cpg/" target="_blank" rel="noopener">here</a>. For further information about greyhound welfare issues, see CPG’s hot topics listed <a href="https://greyhoundcoalition.com/media-resource/" target="_blank" rel="noopener">here</a>.</p> <p style="margin-bottom: 7.95pt; line-height: 12.6pt;"><em>Images: Supplied</em></p>

How efficient is the human brain?

<p><span style="font-size: 14px;">What is the difference between human brains and those of other mammals? Potentially, energy efficiency, according to a </span><a style="font-size: 14px;" rel="noopener" href="https://dx.doi.org/10.1038/s41586-021-04072-3" target="_blank">study</a><span style="font-size: 14px;">, published in </span><em style="font-size: 14px;">Nature.</em></p> <div class="copy"> <p>Neurons in the brain communicate with each other via electrical pulses. These pulses, generated as ions such as potassium and sodium, enter the cell through an ion channel. The channels act as an “on-off” switch by changing shape to alter the flow of the ions, either letting them in and generating an electrical signal, or closing to prevent the signal getting through.</p> <p>Now, a team of researchers from Massachusetts Institute of Technology have found that the number of ion channels in the human brain are at a lower density than in other mammals’ brains. They have hypothesised that this has helped human brains become more efficient.</p> <p>The researchers analysed neurons from 10 mammals – the most extensive electrophysical study of its kind to date – and found that bigger neurons lead to more ion channels in a relatively constant ratio of size-to-channels.</p> <p>What this means is that bigger neurons can still handle all the electrical pulses they are bombarded with because they have the ion channel capacity to process the ions. No matter the brain size, the energetic cost to run each mammal’s brain was about the same.</p> <p><strong>The human brain is the exception</strong></p> <p>That is, in every mammal except humans, who had a much lower density of ion channels than expected.</p> <p>“Previous comparative studies established that the human brain is built like other mammalian brains, so we were surprised to find strong evidence that human neurons are special,” says former MIT graduate student Lou Beaulieu-Laroche.</p> <p>Graphical abstract. Created on imgflip by Cosmos.</p> <p>One benefit of a lower density of ion channels may be that less energy is used on pumping ions into neurons, which could then be diverted to other processes, like creating more complicated synaptic connections.</p> <p>“If the brain can save energy by reducing the density of ion channels, it can spend that energy on other neuronal or circuit processes,” says Mark Harnett, an associate professor of brain and cognitive sciences, a member of MIT’s McGovern Institute for Brain Research, and the senior author of the study.</p> <p>“We think that humans have evolved out of this building plan that was previously restricting the size of cortex, and they figured out a way to become more energetically efficient, so you spend less [energy] per volume compared to other species.”</p> <p>In this case, the human brain could run on the same amount of power as other mammal brains but perform more complex procedures with the excess energy diverted from ion channels.</p> <p>Harnett hopes to study where that extra energy is being used and whether there are any specific genes responsible for ion channel density exclusive to humans.</p> <!-- Start of tracking content syndication.

7 sneaky reasons your hair is going grey too soon

<p><strong>What causes grey hair?</strong></p> <p>Although silver-grey hair is a trendy hair dye colour, many people don’t go grey by choice.</p> <p>And there are different factors that contribute to the process of premature greying.</p> <p>Technically, premature greying is defined as going grey before age 20 if you are white, or before age 30 if you are black, but getting grey hair in your 20s, 30s, or 40s can feel like too soon.</p> <p>In general, grey hairs happen when melanin (natural pigment or colour) stops forming.</p> <p>In general, 74 percent of people aged 45 to 65 will have grey hair with an intensity of about 27 percent, according to a 2012 survey in the <em>British Journal of Dermatology</em>.</p> <p>However, there is a lot of variability. Why does that happen? Here are the reasons why your hair might be turning grey sooner than you’d like.</p> <p><strong>Your parents greyed early</strong></p> <p><span>You’ve probably always wondered what causes grey hair? </span></p> <p><span>Well, steel-coloured locks are partly in your genes, says Dr Doris Day, clinical associate professor of dermatology and author of </span><em>Forget the Facelift</em><span>. </span></p> <p><span>A 2016 study published in </span><em>Nature Communications</em><span> isolated one gene variant linked to greying after researchers analysed hair features of 6,000 Latin Americans. </span></p> <p><span>Though you might be surprised about just how much grey you have if you’ve been colouring your hair for years (or decades), says Dr Day. </span></p> <p><span>And you can blame mum and dad. Just like whether you go bald or not, greying genes come from both sides of the family, says Dr Day.</span></p> <p><strong>You may have an autoimmune condition</strong></p> <p>The autoimmune skin disease called alopecia areata can lead to bright white strands.</p> <p>As the National Alopecia Areata Foundation (NAAF) explains, people with the condition develop small, round, smooth patches on the scalp, and they can completely lose hair on their head or body.</p> <p>“This happens because your immune system attacks your hair follicles, making your hair fall out.</p> <p>When it grows back, it grows back white,” explains Dr Day. If you notice worrisome hair loss or a bald patch, talk to your dermatologist.</p> <p><strong>Your environment is polluted </strong></p> <p><span>Pollutants and toxins can cause you to grey faster, according to the Library of Congress. </span></p> <p><span>These chemicals generate free radicals – or oxidative stress – that damage melanin production and speed hair ageing. </span></p> <p><span>But once hair grows out of the follicle, it’s dead, adds Dr Day. “It’s really about what gets to the follicle level that will make the most marked difference. While these environmental issues may have an impact, other reasons, like stress, matter more,” she says. (More on that in a minute.)</span></p> <p><strong>You're super stressed</strong></p> <p>When US President Barack Obama entered office his hair was dark.</p> <p>Five years later, people were concerned: He completely transformed to silver.</p> <p>The link between stress and grey hair is hotly debated. However, says Dr Day, “stress will accelerate your genetic destiny.”</p> <p>Meaning, if you’re not going to go grey any time soon, stress is unlikely to change your hair colour.</p> <p>But if going grey is in your genes, stress can make your hair turn grey faster and earlier – unless you make an effort to manage stress.</p> <p><strong>You're exposed to cigarette smoke</strong></p> <p><span>If you’re still asking yourself, “What causes grey hair?”, you may want to blame the cigarettes in your house. </span></p> <p><span>Whether it’s you or someone else doing the puffing, exposure to cigarette smoke can affect your hair colour. </span></p> <p><span>Research published in the </span><em>Indian Dermatology Online Journal </em><span>found that smokers have 2.5 times greater odds of early greying, likely because of the huge amounts of free radicals generated by lighting up. </span></p> <p><span>Count this as one more reason to quit – or encourage a loved one to break the habit.</span></p> <p><strong>Your hormones are changing </strong></p> <p><span>One glance at a photo of you a decade ago can tell you this, but your hair is not the same now as it was then. </span></p> <p><span>So, what causes grey hair to start? Thanks to hormones, your hair can change over time in texture, density, and, yes, colour. </span></p> <p><span>“This process starts to be most noticeable when you turn 30. </span><span>That’s the age when people start to come in and complain about these issues,” says Dr Day. </span></p> <p><span>Experts are still trying to understand precisely how hormones (like oestrogen, progesterone and cortisol) influence greying, she says. </span></p> <p><span>And certainly, there are women in their 50s going through menopause who have not a strand of grey hair. It may be a trifecta of events coming to a head: your genetics, environmental factors and hormonal changes.</span></p> <p><strong>It's your age</strong></p> <p>You may not be ready for the grey, but your hair is. Melanin production – what gives hair its pigment – decreases with age.</p> <p>For every decade after you turn 30, your risk of going grey increases 10 to 20 percent, according to the Library of Congress.</p> <p>So while some people may be able to maintain their natural hair colour for longer, it’s inevitable. “In time, everyone’s hair goes grey,” according to the site.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article first appeared in <a rel="noopener" href="https://www.readersdigest.co.nz/healthsmart/beauty/hair-and-nails/7-sneaky-reasons-your-hair-is-going-grey-too-soon" target="_blank">Reader's Digest</a>.</em></p>

The rise of the brown nomads and tips on how to do it

<p>Grey Nomads are a stalwart of the outback campsite, but COVID has seen a surge in younger families hitting the road: the Brown Nomads. These are people whose interstate or overseas jaunts have been thwarted by closed borders, or who have been freed from the 9-to-5 grind and want to take the “work from anywhere” concept literally. However, while adventuring sounds fun, it doesn't always generate a secure income. Consider some good financial planning so you can enjoy the nomadic life <em>and</em> still maintain financial security.</p> <p><strong>Before the trip</strong></p> <p>The options for how to stretch finances depends on your specific circumstances. It's important to see a financial planner early on in this process, but there are a few general tips I can offer.</p> <p><u>Reduce debt.</u> Pay it down as much as you can and see if consolidation makes sense. Do not carry credit card debt into this adventure.</p> <p><u>Plan your income and expenses.</u> Income sources include savings, investment dividends, long service leave, redundancies, ongoing business, or profits from asset sales. Plan expenses, including buying your start-up gear. Many nomads budget for $1000 per week, but it varies. Once you know how much you'll need you can start planning where to take the funds from.</p> <p><u>Interrogate your tax and maximising options</u>. If you’ve received a lump sum and want to use it to kick start your nomadic life, there may be some tax-efficient ways to stretch this amount. Consider various strategies, including a variety of superannuation strategies, consider paying down debt and investing in the name of the partner who didn’t earn an income, or earned less.</p> <p><u>Time your trip to suit your finances</u>. Are there are any benefits to going this or next financial year based on your circumstances?</p> <p><u>Get your financial foundations in place</u>. There are a few things you’ll need to get right as a basis for any secure financial future. These include having an emergency fund, creating a spending plan, getting the right insurances, optimising all aspects of superannuation including fees and investments inside, and having an up to date estate plan.</p> <p><strong>On the trip</strong></p> <p>Now you’ve hit the road and money is flying out the door and not so much is flying back in.</p> <p><u>Review your tax</u>. With the income changes there may be tax incentives you are now eligible for. You could make a spousal superannuation contribution, which will reduce your tax bill. You may also be eligible for the Family Tax Benefit.</p> <p><u>Manage your income streams.</u> Are you relying on income from dividends, term deposits that pay interest or rental income? Should you be? Any income linked to investments can change. Make sure you have enough money parked somewhere to see you through.</p> <p><u>Spend less money. </u>It sounds obvious, but in my experience, people spend what they have. I’ve had clients go from spending $200,000 per year to $40,000 after switching to a nomadic life for a year. When you aren’t in the ‘rat race’ you’ll be surprised how much joy life gives you for free and all the expenses you no longer have.</p> <p><u>Use the nomad community</u>. Experienced nomads will tell you their biggest expense is usually fuel. Find the cheapest with apps like Fuel Map Australia. Second to fuel is accommodation. WikiCamps Australia is one of many apps that has information about sites, including where the free ones are.</p> <p>Packing up and hitting the road does not have to cripple you financially. If you set yourself up right and plan well, you could have the adventure of a lifetime while you’re young, fit and healthy and return to a solid financial foundation.</p> <p>Helen Baker is a licensed Australian financial adviser and author of two books:  <em style="font-weight: bold;">On Your Own Two Feet – Steady Steps to Women’s Financial Independence</em> and On<em style="font-weight: bold;"> Your Own Two Feet Divorce – Your Survive and Thrive Financial Guide</em>.  <em style="font-weight: bold;">Proceeds from the books’ sales are donated to charities supporting disadvantaged women.  </em>Helen is among the 1% of financial planners who holds a master’s degree in the field.

Stone tools reveal epic trek of nomadic Neanderthals

<p>Neanderthal (<em>Homo neanderthalensis</em>) fossils were first discovered in western Europe in the mid nineteenth century. That was just the first in a long line of surprises thrown up by our closest evolutionary cousins.</p> <p>We reveal another in <a href="https://www.pnas.org/content/early/2020/01/21/1918047117">our new study</a> of the Neanderthals who lived in Chagyrskaya Cave in southern Siberia around 54,000 years ago. Their distinctive stone tools are dead ringers for those found thousands of kilometres away in eastern and central Europe.</p> <p>The intercontinental journey made by these intrepid Neanderthals is equivalent to walking from Sydney to Perth, or from New York to Los Angeles, and is a rare example of long-distance migration by Palaeolithic people.</p> <p><strong>Knuckleheads no more</strong></p> <p>For a long time Neanderthals were seen as intellectual lightweights. However, <a href="https://theconversation.com/neanderthals-were-no-brutes-research-reveals-they-may-have-been-precision-workers-103858">several recent finds</a> have forced a rethink of their cognitive and creative abilities.</p> <p>Neanderthals are now believed to have created 176,000 year-old enigmatic structures made from broken stalactites in a <a href="https://www.nationalgeographic.com/news/2016/05/neanderthals-caves-rings-building-france-archaeology/">cave in France</a>, and <a href="https://theconversation.com/how-we-discovered-that-neanderthals-could-make-art-92127">cave art in Spain</a>that dates back more than 65,000 years.</p> <p>They also used <a href="https://doi.org/10.1371/journal.pone.0045927">bird feathers</a> and <a href="https://doi.org/10.1126/sciadv.aar5255">pierced shells</a> bearing traces of red and yellow ochre, possibly as personal ornaments. It seems likely Neanderthals had cognitive capabilities and symbolic behaviours similar to those of modern humans (<em>Homo sapiens</em>).</p> <p>Our knowledge of their geographical range and the nature of their encounters with other groups of humans has also expanded greatly in recent years.</p> <p>We now know that Neanderthals ventured beyond Europe and western Asia, reaching at least as far east as the Altai Mountains. Here, they interbred with another group of archaic humans dubbed the <a href="https://www.smithsonianmag.com/science-nature/scientists-recreate-face-denisovan-using-dna-180973177/">Denisovans</a>.</p> <p>Traces of Neanderthal interactions with our own ancestors also persist in the DNA of all living people of Eurasian descent. However, we can still only speculate why the Neanderthals vanished around 40,000 years ago.</p> <p><strong>Banished to Siberia</strong></p> <p>Other questions also remain unresolved. When did Neanderthals first arrive in the Altai? Were there later migration events? Where did these trailblazers begin their trek? And what routes did they take across Asia?</p> <p><a href="https://www.antiquity.ac.uk/projgall/derevyanko345">Chagyrskaya Cave</a> is nestled in the foothills of the Altai Mountains. The cave deposits were first excavated in 2007 and have yielded almost 90,000 stone tools and numerous bone tools.</p> <p>The excavations have also found 74 Neanderthal fossils – the richest trove of any Altai site – and a range of animal and plant remains, including the abundant bones of bison hunted and butchered by the Neanderthals.</p> <p>We used <a href="https://www.nature.com/articles/520438a">optical dating</a> to determine when the cave sediments, artefacts and fossils were deposited, and conducted a detailed study of more than 3,000 stone tools recovered from the deepest archaeological levels. Microscopy analysis revealed that these have remained intact and undisturbed since accumulating during a period of cold and dry climate about 54,000 years ago.</p> <p>Using a variety of statistical techniques, we show that these artefacts bear a striking similarity to so-called <a href="https://en.wikipedia.org/wiki/Micoquien">Micoquian</a> artefacts from central and eastern Europe. This type of <a href="https://en.wikipedia.org/wiki/Middle_Paleolithic">Middle Palaeolithic</a> assemblage is readily identified by the distinctive appearance of the bifaces – tools made by removing flakes from both sides – which were used to cut meat.</p> <p>Micoquian-like tools have only been found at one other site in the Altai. All other archaeological assemblages in the Altai and central Asia lack these distinctive artefacts.</p> <p>Neanderthals carrying Micoquian tools may never have reached <a href="https://www.nature.com/articles/d41586-019-00353-0">Denisova Cave</a>, as there is no fossil or sedimentary DNA evidence of Neanderthals there after 100,000 years ago.</p> <p><strong>Going the distance</strong></p> <p>The presence of Micoquian artefacts at Chagyrskaya Cave suggests at least two separate dispersals of Neanderthals into southern Siberia. Sites such as Denisova Cave were occupied by Neanderthals who entered the region before 100,000 years ago, while the Chagyrskaya Neanderthals arrived later.</p> <p>The Chagyrskaya artefacts most closely resemble those found at sites located 3,000–4,000 km to the west, between the Crimea and northern Caucasus in eastern Europe.</p> <p>Comparison of genetic data supports these geographical links, with the <a href="https://www.eva.mpg.de/genetics/genome-projects/chagyrskaya-neandertal/home.html">Chagyrskaya Neanderthal</a> sharing closer affinities with several European Neanderthals than with a Neanderthal from Denisova Cave.</p> <p>When the Chagyrskaya toolmakers (or their ancestors) left their Neanderthal homeland in eastern Europe for central Asia around 60,000 years ago, they could have headed north and east around the land-locked <a href="https://www.britannica.com/place/Caspian-Sea">Caspian Sea</a>, which was much reduced in size under the prevailing cold and arid conditions.</p> <p>Their intercontinental odyssey over thousands of kilometres is a rarely observed case of long-distance dispersal in the Palaeolithic, and highlights the value of stone tools as culturally informative markers of ancient population movements.</p> <p>Environmental reconstructions from the animal and plant remains at Chagyrskaya Cave suggest that the Neanderthal inhabitants survived in the cold, dry and treeless environment by hunting bison and horses on the steppe or tundra-steppe landscape.</p> <p>Our discoveries reinforce the emerging view of Neanderthals as creative and intelligent people who were skilled survivors. If this was the case, it makes their extinction across Eurasia even more mysterious. Did modern humans deal the fatal blow? The enigma endures, for now.</p> <p><em>Written by Kseniya Kolobova, Maciej T. Krajcarz and Richard 'Bert' Roberts.

Everything you need to know about going grey

<p>Everyone remembers the day they woke up to find a grey hair. It’s a rite of passage, a sign of wisdom and a life well lived. But while those with steel strands should embrace the hue, the question remains: Why do we go grey? And is there anything that can be done to prevent our hair from losing its natural pigment?</p> <p><strong>Why does your hair turn grey?</strong></p> <p>According to research conducted by the Department of Dermatology at Mount Sinai Hospital, the average age men and women start to see grey hair is between 34 and 44. But if you’re someone who noticed your hair turning white before you hit your 30s, then chances are it’s due to genetics.</p> <p>Hair follicles contain pigment cells that produce melanin – which is responsible for giving your hair its natural colour. As we age, the body stops generating melanin resulting in grey hair.</p> <p>Sure, there are other factors to consider, such as stress, but experts say the correlation between stress and grey hair is yet to be proven.</p> <p>“It is unclear whether emotional stress is truly associated with greying of the hair,” Joshua Ziechner, director of cosmetic and clinical research at the Mount Sinai Department of Dermatology told <span><em><a href="https://www.allure.com/story/gray-hair-guide-causes-and-care">Allure</a></em></span>.</p> <p>“We know that stress can have physical effects, interfering with wound healing and promoting inflammation. We don’t know how significant of an impact it has on hair colour, but I would not be surprised if one day a definite association is found.”</p> <p><strong>What makes grey hair different from other hair?</strong></p> <p>It’s long been thought that grey hair is much coarser in texture than coloured hair, but that myth has been debunked. While grey hair can feel rough, it’s actually much finer than your natural hair. The reason for its dry appearance is due to oil glands.</p> <p>You see, oil glands are responsible for providing a lubricant to the hair, and as we age, our bodies produce less sebum, meaning your follicles will appear to be much drier.</p> <p>“It is unclear why, but the biological process that affects the colour of the hair likely also affects the structure of the hair being produced as well,” says Zeichner, which may put a dampener on your mood, but is a plus when it comes to styling hair as grey strands hold curls better!</p> <p>Speaking to <em>Allure</em>, colourist Jax Williard said: “A lot of women get discouraged from going grey, but the texture [greys] give you can actually make your hair routine more exciting. Your hair might dry much quicker, and you might feel that it is much thicker, holding styles better and longer. That being said, you should also focus on keeping your hair very moisturised from roots to ends. This will keep it soft and shiny.”</p> <p><strong>How do you care for grey hair?</strong></p> <p>Congratulations! You’ve decided to become a silver fox or vixen and rock what you’ve got. You’re in good company, with women such as Jamie Lee Curtis and Emma Thompson flashing the brilliant hue. But before you commit, it’s important to understand exactly how to care for your new locks.</p> <p>First things first, grab yourself some blue or purple shampoo. While it may sound like a ridiculous concept, the coloured shampoo helps cancel out any brassiness that may appear, and also helps keep your hair looking brighter for longer.</p> <p>Using a purple or blue-toned shampoo a few times a month will help keep your strands in optimal condition, but be sure not to go overboard, as excessive use may dry out your hair further.</p> <p>And speaking of dry hair, the words “hydrating” and “nourishing” are your best friends. For your everyday shampoo, you want it full of antioxidants to help revive your hair as chances are, it’ll be a little thirsty.</p> <p>But if shampoo isn’t providing enough moisture for you, then Aura Freidman, a colourist at the Sally Hershberger Tim Rogers salon in New York City let <em>Allure </em>in on a genius alternative: “I always recommend a cleansing milk,” she says. “I find it much more moisturising and it keeps the hair from getting too dry. With grey hair, it tends to [feel] a little bit dryer. It has a different texture. A cool blonde conditioner is great – the shampoo tends to dry out the hair, but the conditioner deposits the tone, conditions the hair and adds moisture.”</p> <p>Are you planning to ditch the dyes and embrace your grey hair?

Why some people’s hair goes grey early – according to science

<p>The age in which a person starts having grey hair can differ greatly from person to person – with some people becoming a silver fox in their 20s.</p> <p>Now, a new mouse study suggests that viral infections could play a role in triggering grey hair early on in life.</p> <p>When mice are exposed to a virus, they suffer a loss of melanocyte stem cells which leads to an increased number of grey hairs, reported <em><a href="https://au.news.yahoo.com/peoples-hair-goes-grey-early-according-science-064326747.html" target="_blank"><span style="text-decoration: underline;"><strong>Yahoo! 7</strong></span></a>.</em></p> <p>Melissa Harris of the University of Alabama at Birmingham said that when a virus attacks the immune system, infected cells respond by producing interferons.</p> <p>Interferons signal messages to neighbouring cells, warning them to protect themselves.</p> <p>When there is an excess number of interferons, there can also be a loss of melanocytes and melanocyte stem cells, which stop the production of hair pigmentation.</p> <p>Harris says that this could explain why some people go grey in their early years.</p> <p>“Perhaps, in an individual who is healthy yet predisposed for grey hair, getting an everyday viral infection is just enough to cause the decline of their melanocytes and melanocyte stem cells leading to premature grey hair,” Harris explains. </p> <p>How old were you when you started going grey?

Why are grey-haired men revered while grey-haired women are silenced?

<p>They've christened it the 'Clooney Effect' – the greyer the hair, the more attractive the man. Even the bird kingdom isn't immune, say British ornithologists, who recently discovered that when certain male birds go grey, it automatically sends the female of the species into a flutter. </p> <p>For reasons far too absurd to squander my word count on, blokes such as George Clooney are seen as 'silver foxes' – sexy, powerful, distinguished and wise. Women, on the other hand, rarely make it past the bouncer at this party. Wear your grey pride as a woman and you'll be labelled an old hippy, crazy cat lady, accused of 'letting yourself go' and/or of dabbling in the dark arts.</p> <p>Like it or not, ours is a culture that reveres and worships youth, that believes getting older is something to be feared and avoided. Enter the billion dollar 'hope in a jar' industries, with their potions, scalpels, suck-in-the-fat knickers and hair dyes, which paper over our anxieties and promise a youthful glow.</p> <p>A recent European survey, for example, found that more than 50 percent of executive women dye their hair, as opposed to just three percent of men. As one of the survey respondents put it, "Grey hair makes a businessman look distinguished, but it just makes a woman look old and tired."</p> <p>There are lots of reasons hair turns grey: genetics, stress, poor diet. The science behind it, though, is pretty simple: as we age, the follicles at the base of the hair shaft stop producing melanin, which, in turn, produces pigment. Getting older equals the death of pigment. We've been trying to dial back the grey ever since the ancient Romans slapped boiled walnuts on their locks. </p> <p>Over the years, everything from plants and onion skins to turmeric and henna have been called into service; a particularly low point was the turn of last century when early adopters of peroxide-based dyes often left the salon with violent headaches, swollen eyelids and blisters on their foreheads.</p> <p>When I was at primary school a friend's mother paid us five cents every time we found one of her grey hairs. She would hand us a pair of tweezers and we would yank them out with sufficient enthusiasm to keep us in $1 lolly bags. To my childish eyes, she was pretty, successful and fun; I couldn't understand why she was so keen to be rid of the silvery strands that snaked across her head. </p> <p>Foolishly believing I could trump both convention and genetics, I swore I'd never do the same. I was wrong. Unlike a friend who spotted her first grey hair at 10, I came late to the greying game. I was 28 when I found my first grey hair; I plucked it out and angrily flushed it down the loo. The next week it came back – and this time it had brought friends.</p> <p>As I hobbled across the threshold of my 30s, those silver suckers kept coming. Every 10 weeks I would pay someone to torture my follicles. It was expensive and time consuming (that's a helluva long time to be sitting in a chair with crap on your head reading trashy magazines). </p> <p>My colourist likened it to the Hotel California – you can dye your hair any time you like, but you can never stop. Still, I told myself, it was worth it to slug my way back to an earlier version of myself. A few years ago a friend saved me from bankruptcy by switching me on to home dye jobs. They're not nearly as effective, and I often dye random bits of the bathroom walls, but they're cheaper and much less time consuming.</p> <p>I could, of course, always follow Vogue fashion director Sarah Harris who recently decided to challenge society's 'white fright'. "I'm embracing the rebelliousness of my grey hair. It is honest and non-conformist," she wrote. Or actresses such as Helen Mirren and Jamie Lee Curtis, both rich enough to buy all the hair dye in the world but who choose not to camouflage the grey. </p> <p>Or American author Anne Kreamer who wrote a book about her journey into grey. "We only fool ourselves about how young we look with dyed hair," believes Kreamer. In an interesting aside, Kreamer conducted an experiment to see how men view women with grey hair. She posted two profiles on a dating website -one of her with grey hair, the other with brown. Three times as many men wanted to date her with grey hair.</p> <p>"Maybe the men sensed that if I was being honest about the colour of my hair, I'd be more accessible and easier to date. Or maybe the grey made me standout from the overwhelming majority of women on the site who colour their hair."</p> <p>Sadly, I lack the confidence (and cheekbones) of Mirren, Kreamer and co. I don't feel comfortable having shiny silver hairs sticking out the top of my head and I'm not ready to give up my irresponsible relationship with dye. Sadly, no amount of wishing will turn my hair back to what it once was, but while I wait for the vanity and fear to wear itself out, I'll keep reaching for Clairol.</p> <p><em>Written by Sharon Stephenson.
