Beat Food Addictions!

When It’s More Than “Just” Cravings
This is Dr. Nicole Avena. She’s a research neuroscientist who also teaches at Mount Sinai School of Medicine, as well as at Princeton. She’s done a lot of groundbreaking research in the field of nutrition, diet, and addition, with a special focus on women’s health and sugar intake specifically.
What does she want us to know?
Firstly, that food addictions are real addictions.
We know it can sound silly, like the famous line from Mad Max:
❝Do not, my friends, become addicted to water. It will take hold of you and you will resent its absence!❞
As an aside, it is actually possible to become addicted to water; if one drinks it excessively (we are talking gallons every day) it does change the structure of the brain (no surprise; the brain is not supposed to have that much water!) causing structural damage that then results in dependency, and headaches upon withdrawal. It’s called psychogenic polydipsia:
But back onto today’s more specific topic, and by a different mechanism of addiction…
Food addictions are dopaminergic addictions (as is cocaine)
If you are addicted to a certain food (often sugar, but other refined carbs such as potato products, and also especially refined flour products, are also potential addictive substances), then when you think about the food in question, your brain lights up with more dopamine than it should, and you are strongly motivated to seek and consume the substance in question.
Remember, dopamine functions by expectation, not by result. So until your brain’s dopamine-gremlin is sated, it will keep flooding you with motivational dopamine; that’s why the first bite tastes best, then you wolf down the rest before your brain can change its mind, and afterwards you may be left thinking/feeling “was that worth it?”.
Much like with other addictions (especially alcohol), shame and regret often feature strongly afterwards, even accompanied by notions of “never again”.
But, binge-eating is as difficult to escape as binge-drinking.
You can break free, but you will probably have to take it seriously
Dr. Avena recommends treating a food addiction like any other addiction, which means:
- Know why you want to quit (make a list of the reasons, and this will help you stay on track later!)
- Make a conscious decision to genuinely quit
- Learn about the nature of the specific addiction (know thy enemy!)
- Choose a strategy (e.g. wean off vs cold turkey, and decide what replacements, if any, you will use)
- Get support (especially from those around you, and/but the support of others facing, or who have successfully faced, the same challenge is very helpful too)
- Keep track of your success (build and maintain a streak!)
- Lean into how you will better enjoy life without addiction to the substance (it never really made you happy anyway, so enjoy your newfound freedom and good health!)

Take Care Of Your “Unwanted” Parts Too!

Meet The Family…
If you’ve heard talk of “healing your inner child” or similar ideas, then today’s featured type of therapy takes that to several extra levels, in a way that helps many people.
It’s called Internal Family Systems therapy, often “IFS” for short.
Here’s a quick overview:
Psychology Today | Internal Family Systems Therapy
Note: if you are delusional, paranoid, schizophrenic, or have some other related disorder*, then IFS would probably be a bad idea for you as it could worsen your symptoms, and/or play into them badly.
*but bipolar disorder, in its various forms, is not usually a problem for IFS. Do check with your own relevant healthcare provider(s), of course, to be sure.
What is IFS?
The main premise of IFS is that your “self” can be modelled as a system, and its constituent parts can be examined, questioned, given what they need, and integrated into a healthy whole.
For example…
- Exile is the name given to parts that could be, for example, the “inner child” referenced in a lot of pop-psychology, but it could also be some other ignored and pushed-down part of oneself, often from some kind of trauma. The defining characteristic of an exile is that it’s a part of ourself that we don’t consciously allow ourselves to see as a current part of ourself.
- Protector is the name given to a part of us that looks to keep us safe, and can do this in an adaptive (healthy) or maladaptive (unhealthy) way, for example:
- Firefighter is the name given to a part of us that will do whatever is necessary in the moment to deal with an exile that is otherwise coming to the surface—sometimes with drastic actions/reactions that may not be great for us.
- Manager is the name given to a part of us that has a more nurturing protective role, keeping us from harm in what’s often a more prophylactic manner.
To give a simple illustration…
A person was criticized a lot as a child, told she was useless, and treated as a disappointment. Consequently, as an adult she now has an exile “the useless child”, something she strives to leave well behind in her past, because it was a painful experience for her. However, sometimes when someone questions and/or advises her, she will get defensive as her firefighter “the hero” will vigorously speak up for her competence, like nobody did when she was a child. This vigor, however, manifests as rude abrasiveness and overcompensation. Finally, she has a manager, “the advocate”, who will do the same job, but in a more quietly confident fashion.
This person’s therapy will look at transferring the protector job from the firefighter to the manager, which will involve examining, questioning, and addressing all three parts.
The above example is fictional and created for simplicity and clarity; here’s a real-world case study if you’d like a more in-depth overview of how it can work:
How it all fits together in practice
IFS looks to make sure all the parts’ needs are met, even the “bad” ones, because they all have their functions.
Good IFS therapy, however, can make sure a part is heard, and then reassure that part in a way that effectively allows that part to “retire”, safe and secure in the knowledge that it has done what it needed to, and/or the job is being done by another part now.
That can involve, for example, thanking the firefighter for looking after our exile for all these years, but that our exile is safe and in good hands now, so it can put that fire-axe away.
See also: On Being Reactive vs Being Responsive
Questions you might ask yourself
While IFS therapy is best given by a skilled practitioner, we can take some of the ideas of it for self-therapy too. For example…
- What is a secret about yourself that you will take to the grave? And now, why did that part of you (now an exile) come to exist?
- What does that exile need, that it didn’t get? What parts of us try to give it that nowadays?
- What could we do, with all that information in mind, to assign the “protection” job to the part of us best-suited to healthy integration?

Do we really need to burp babies? Here’s what the research says
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Parents are often advised to burp their babies after feeding them. Some people think burping after feeding is important to reduce or prevent discomfort crying, or to reduce how much a baby regurgitates milk after a feed.
It is true babies, like adults, swallow air when they eat. Burping releases this air from the top part of our digestive tracts. So when a baby cries after a feed, many assume it’s because the child needs to “be burped”. However, this is not necessarily true.
Why do babies cry or ‘spit up’ after a feed?
Babies cry for a whole host of reasons that have nothing to do with “trapped air”.
They cry when they are hungry, cold, hot, scared, tired, lonely, overwhelmed, needing adult help to calm, in discomfort or pain, or for no identifiable reason. In fact, we have a name for crying with no known cause; it’s called “colic”.
“Spitting up” – where a baby gently regurgitates a bit of milk after a feed – is common because the muscle at the top of a newborn baby’s stomach is not fully mature. This means what goes down can all too easily go back up.
Spitting up frequently happens when a baby’s stomach is very full, there is pressure on their tummy or they are picked up after lying down.
Spitting up after feeding decreases as babies get older. Three-quarters of babies one month old spit up after feeding at least once a day. Only half of babies still spit up at five months and almost all (96%) stop by their first birthdays.
Does burping help reduce crying or spitting up?
Despite parents being advised to burp their babies, there’s not much research evidence on the topic.
One study conducted in India encouraged caregivers of 35 newborns to burp their babies, while caregivers of 36 newborns were not given any information about burping.
For the next three months, mothers and caregivers recorded whether their baby would spit up after feeding and whether they showed signs of intense crying.
This study found burping did not reduce crying and actually increased spitting up.
When should I be concerned about spitting up or crying?
Most crying and spitting up is normal. However, these behaviours are not:
- refusing to feed
- vomiting so much milk weight gain is slow
- coughing or wheezing distress while feeding
- bloody vomit.
If your baby has any of these symptoms, see a doctor or child health nurse.
If your baby seems unbothered by vomiting and does not have any other symptoms it is a laundry problem rather than something that needs medical attention.
It is also normal for babies to cry and fuss quite a lot; two hours a day, for about the first six weeks is the average.
This has usually reduced to about one hour a day by the time they are three months of age.
Crying more than this doesn’t necessarily mean there is something wrong. The intense, inconsolable crying of colic is experienced by up to one-quarter of young babies but goes away with time on its own .
If your baby is crying more than average or if you are worried there might be something wrong, you should see your doctor or child health nurse.
Not everyone burps their baby
Burping babies seems to be traditional practice in some parts of the world and not in others.
For example, research in Indonesia found most breastfeeding mothers rarely or never burped their babies after feeding.
One factor that may influence whether a culture encourages burping babies may be related to another aspect of infant care: how much babies are carried.
Carrying a baby in a sling or baby carrier can reduce the amount of time babies cry.
Babies who are carried upright on their mother or another caregiver’s front undoubtedly find comfort in that closeness and movement.
Babies in slings are also being held firmly and upright, which would help any swallowed air to rise up and escape via a burp if needed.
Using slings can make caring for a baby easier. Studies (including randomised controlled trials) have also shown women have lower rates of post-natal depression and breastfeed for longer when they use a baby sling.
It is important baby carriers and slings are used safely, so make sure you’re up to date on the latest advice on how to do it.
So, should I burp my baby?
The bottom line is: it’s up to you.
Gently burping a baby is not harmful. If you feel burping is helpful to your baby, then keep doing what you’re doing.
If trying to burp your baby after every feed is stressing you or your baby out, then you don’t have to keep doing it.

The Oh She Glows Cookbook – by Angela Liddon
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Let’s get the criticism out of the way first: notwithstanding the subtitle promising over 100 recipes, there are about 80-odd here, if we discount recipes that are no-brainer things like smoothies, sides such as for example “roasted garlic”, or meta-ingredients such as oat flour (instructions: blend the oats and you get oat flour).
The other criticism is more subjective: if you are like this reviewer, you will want to add more seasonings than recommended to most of the recipes. But that’s easy enough to do.
As for the rest: this is a very healthy cookbook, and quite wide-ranging and versatile, with recipes that are homely, with a lot of emphasis on comfort foods (but still, healthy), though certainly some are perfectly worthy of entertaining too.
A nice bonus of this book is that it offers a lot of available substitutions (much like we do at 10almonds), and also ways of turning the recipe into something else entirely with just a small change. This trait more than makes up for the slight swindle in terms of number of recipes, since some of the recipes have bonus recipes snuck in.
Bottom line: if you’d like to broaden your plant-based cooking range, this book is a fine option for expanding your repertoire.

They Were Injured at the Super Bowl Parade. A Month Later, They Feel Forgotten.
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
KFF Health News and KCUR are following the stories of people injured during the Feb. 14 mass shooting at the Kansas City Chiefs Super Bowl celebration. Listen to how one Kansas family is coping with the trauma.
Jason Barton didn’t want to attend the Super Bowl parade this year. He told a co-worker the night before that he worried about a mass shooting. But it was Valentine’s Day, his wife is a Kansas City Chiefs superfan, and he couldn’t afford to take her to games since ticket prices soared after the team won the championship in 2020.
So Barton drove 50 miles from Osawatomie, Kansas, to downtown Kansas City, Missouri, with his wife, Bridget, her 13-year-old daughter, Gabriella, and Gabriella’s school friend. When they finally arrived home that night, they cleaned blood from Gabriella’s sneakers and found a bullet in Bridget’s backpack.
Gabriella’s legs were burned by sparks from a ricocheted bullet, Bridget was trampled while shielding Gabriella in the chaos, and Jason gave chest compressions to a man injured by gunfire. He believes it was Lyndell Mays, one of two men charged with second-degree felony murder.
“There’s never going to be a Valentine’s Day where I look back and I don’t think about it,” Gabriella said, “because that’s a day where we’re supposed to have fun and appreciate the people that we have.”
One month after the parade in which the U.S. public health crisis that is gun violence played out on live television, the Bartons are reeling from their role at its epicenter. They were just feet from 43-year-old Lisa Lopez-Galvan, who was killed. Twenty-four other people were injured. Although the Bartons aren’t included in that official victim number, they were traumatized, physically and emotionally, and pain permeates their lives: Bridget and Jason keep canceling plans to go out, opting instead to stay home together; Gabriella plans to join a boxing club instead of the dance team.
During this first month, Kansas City community leaders have weighed how to care for people caught in the bloody crossfire and how to divide more than $2 million donated to public funds for victims in the initial outpouring of grief.
The questions are far-reaching: How does a city compensate people for medical bills, recovery treatments, counseling, and lost wages? And what about those who have PTSD-like symptoms that could last years? How does a community identify and care for victims often overlooked in the first flush of reporting on a mass shooting: the injured?
The injured list could grow. Prosecutors and Kansas City police are mounting a legal case against four of the shooting suspects, and are encouraging additional victims to come forward.
“Specifically, we’re looking for individuals who suffered wounds from their trying to escape. A stampede occurred while people were trying to flee,” said Jackson County Prosecutor Jean Peters Baker. Anyone who “in the fleeing of this event that maybe fell down, you were trampled, you sprained an ankle, you broke a bone.”
Meanwhile, people who took charge of raising money and providing services to care for the injured are wrestling with who gets the money — and who doesn’t. Due to large donations from celebrities like Taylor Swift and Travis Kelce, some victims or their families will have access to hundreds of thousands of dollars for medical expenses. Other victims may simply have their counseling covered.
The overall economic cost of U.S. firearm injuries is estimated by a recent Harvard Medical School study at $557 billion annually. Most of that — 88% — represented quality-of-life losses among those injured by firearms and their families. The JAMA-published study found that each nonfatal firearm injury leads to roughly $30,000 in direct health care spending per survivor in the first year alone.
In the immediate aftermath of the shootings, as well-intentioned GoFundMe pages popped up to help victims, executives at United Way of Greater Kansas City gathered to devise a collective donation response. They came up with “three concentric circles of victims,” said Jessica Blubaugh, the United Way’s chief philanthropy officer, and launched the #KCStrong campaign.
“There were folks that were obviously directly impacted by gunfire. Then the next circle out is folks that were impacted, not necessarily by gunshots, but by physical impact. So maybe they were trampled and maybe they tore a ligament or something because they were running away,” Blubaugh said. “Then third is folks that were just adjacent and/or bystanders that have a lot of trauma from all of this.”
PTSD, Panic, and the Echo of Gunfire
Bridget Barton returned to Kansas City the day after the shooting to turn in the bullet she found in her backpack and to give a statement at police headquarters. Unbeknownst to her, Mayor Quinton Lucas and the police and fire chiefs had just finished a press conference outside the building. She was mobbed by the media assembled there — interviews that are now a blur.
“I don’t know how you guys do this every day,” she remembered telling a detective once she finally got inside.
The Bartons have been overwhelmed by well wishes from close friends and family as they navigate the trauma, almost to the point of exhaustion. Bridget took to social media to explain she wasn’t ignoring the messages, she’s just responding as she feels able — some days she can hardly look at her phone, she said.
A family friend bought new Barbie blankets for Gabriella and her friend after the ones they brought to the parade were lost or ruined. Bridget tried replacing the blankets herself at her local Walmart, but when she was bumped accidentally, it triggered a panic attack. She abandoned her cart and drove home.
“I’m trying to get my anxiety under control,” Bridget said.
That means therapy. Before the parade, she was already seeing a therapist and planning to begin eye movement desensitization and reprocessing, a form of therapy associated with treating post-traumatic stress disorder. Now the shooting is the first thing she wants to talk about in therapy.
Since Gabriella, an eighth grader, has returned to middle school, she has dealt with the compounding immaturity of adolescence: peers telling her to get over it, pointing finger guns at her, or even saying it should have been her who was shot. But her friends are checking on her and asking how she’s doing. She wishes more people would do the same for her friend, who took off running when the shooting started and avoided injury. Gabriella feels guilty about bringing her to what turned into a horrifying experience.
“We can tell her all day long, ‘It wasn’t your fault. She’s not your responsibility.’ Just like I can tell myself, ‘It wasn’t my fault or my responsibility,’” Bridget said. “But I still bawled on her mom’s shoulder telling her how sorry I was that I grabbed my kid first.”
The two girls have spent a lot of time talking since the shooting, which Gabriella said helps with her own stress. So does spending time with her dog and her lizard, putting on makeup, and listening to music — Tech N9ne’s performance was a highlight of the Super Bowl celebration for her.
In addition to the spark burns on Gabriella’s legs, when she fell to the concrete in the pandemonium she split open a burn wound on her stomach previously caused by a styling iron.
“When I see that, I just picture my mom trying to protect me and seeing everyone run,” Gabriella said of the wound.
It’s hard not to feel forgotten by the public, Bridget said. The shooting, especially its survivors, have largely faded from the headlines aside from court dates. Two additional high-profile shootings have occurred in the area since the parade. Doesn’t the community care, she wonders, that her family is still living with the fallout every day?
“I’m going to put this as plainly as possible. I’m f—ing pissed because my family went through something traumatic,” Bridget vented in a recent social media post. “I don’t really want anything other [than], ‘Your story matters, too, and we want to know how you’re doing.’ Have we gotten that? Abso-f—lutely not.”
‘What Is the Landscape of Need?’
Helped in part by celebrities like Swift and Kelce, donations for the family of Lopez-Galvan, the lone fatality, and other victims poured in immediately after the shootings. Swift and Kelce donated $100,000 each. With the help of an initial $200,000 donation from the Kansas City Chiefs, the United Way’s #KCStrong campaign took off, reaching $1 million in the first two weeks and sitting at $1.2 million now.
Six verified GoFundMe funds were established. One solely for the Lopez-Galvan family has collected over $406,000. Smaller ones were started by a local college student and Swift fans. Churches have also stepped up, and one local coalition had raised $183,000, money set aside for Lopez-Galvan’s funeral, counseling services for five victims, and other medical bills from Children’s Mercy Kansas City hospital, said Ray Jarrett, executive director of Unite KC.
Money for Victims Rolls In
Donations poured in for those injured at the Super Bowl Parade in Kansas City after the Feb. 14 shootings. The largest, starting with a $200,000 donation from the Kansas City Chiefs, is at the United Way of Greater Kansas City. Six GoFundMe sites also popped up, due in part to $100,000 donations each from Taylor Swift and Travis Kelce. Here’s a look at the totals as of March 12.United Way#KCStrong: $1.2 million.Six Verified GoFundMe AccountsLisa Lopez-Galvan GoFundMe (Taylor Swift donated): $406,142Reyes Family GoFundMe (Travis Kelce donated): $207,035Samuel Arellano GoFundMe: $11,896Emily Tavis GoFundMe: $9,518Cristian Martinez’s GoFundMe for United Way: $2,967Swifties’ GoFundMe for Children’s Mercy hospital: $1,060ChurchesResurrection (Methodist) “Victims of Violence Fund”: $53,358‘The Church Loves Kansas City’: $183,000
Meanwhile, those leading the efforts found models in other cities. The United Way’s Blubaugh called counterparts who’d responded to their own mass shootings in Orlando, Florida; Buffalo, New York; and Newtown, Connecticut.
“The unfortunate reality is we have a cadre of communities across the country who have already faced tragedies like this,” Blubaugh said. “So there is an unfortunate protocol that is, sort of, already in place.”
#KCStrong monies could start being paid out by the end of March, Blubaugh said. Hundreds of people called the nonprofit’s 211 line, and the United Way is consulting with hospitals and law enforcement to verify victims and then offer services they may need, she said.
The range of needs is staggering — several people are still recovering at home, some are seeking counseling, and many weren’t even counted in the beginning. For instance, a plainclothes police officer was injured in the melee but is doing fine now, said Police Chief Stacey Graves.
Determining who is eligible for assistance was one of the first conversations United Way officials had when creating the fund. They prioritized three areas of focus: first were the wounded victims and their families, second was collaborating with organizations already helping victims in violence intervention and prevention and mental health services, and third were the first responders.
Specifically, the funds will be steered to cover medical bills, or lost wages for those who haven’t been able to work since the shootings, Blubaugh said. The goal is to work quickly to help people, she said, but also to spend the money in a judicious, strategic way.
“We don’t have a clear sightline of the entire landscape that we’re dealing with,” Blubaugh said. “Not only of how much money do we have to work with, but also, what is the landscape of need? And we need both of those things to be able to make those decisions.”
Firsthand Experience of Daily Kansas City Violence
Jason used his lone remaining sick day to stay home with Bridget and Gabriella. An overnight automation technician, he is the family’s primary breadwinner.
“I can’t take off work, you know?” he said. “It happened. It sucked. But it’s time to move on.”
“He’s a guy’s guy,” Bridget interjected.
On Jason’s first night back at work, the sudden sound of falling dishes startled Bridget and Gabriella, sending them into each other’s arms crying.
“It’s just those moments of flashbacks that are kicking our butts,” Bridget said.
Tell Us About Your Experience
We are continuing to report on the effects of the parade shooting on the people who were injured and the community as a whole. Do you have an experience you want to tell us about, or a question you think we should look into? Message KCUR’s text line at (816) 601-4777. Your information will not be used in an article without your permission.
In a way, the shooting has brought the family closer. They’ve been through a lot recently. Jason survived a heart attack and cancer last year. Raising a teenager is never easy.
Bridget can appreciate that the bullet lodged in her backpack, narrowly missing her, and that Gabriella’s legs were burned by sparks but she wasn’t shot.
Jason is grateful for another reason: It wasn’t a terrorist attack, as he initially feared. Instead, it fits into the type of gun violence he’d become accustomed to growing up in Kansas City, which recorded its deadliest year last year, although he’d never been this close to it before.
“This crap happens every single day,” he said. “The only difference is we were here for it.”

Do We Need Sunscreen In Winter, Really?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝I keep seeing advice that we shoudl wear sunscreen out in winter even if it’s not hot or sunny, but is there actually any real benefit to this?❞
Short answer: yes (but it’s indeed not as critical as it is during summer’s hot/sunny days)
Longer answer: first, let’s examine the physics of summer vs winter when it comes to the sun…
In summer (assuming we live far enough from the equator to have this kind of seasonal variation), the part of the planet where we live is tilted more towards the sun. This makes it closer, and more importantly, it’s more directly overhead during the day. The difference in distance through space isn’t as big a deal as the difference in distance through the atmosphere. When the sun is more directly overhead, its rays have a shorter path through our atmosphere, and thus less chance of being blocked by cloud cover / refracted elsewhere / bounced back off into space before it even gets that far.
In winter, the opposite of all that is true.
Morning/evening also somewhat replicate this compared to midday, because the sun being lower in the sky has a similar effect to seasonal variation causing it to be less directly overhead.
For this reason, even though visually the sun may be just as bright on a winter morning as it is on a summer midday, the rays have been filtered very differently by the time they get to us.
This is one reason why you’re much less likely to get sunburned in the winter, compared to the summer (others include the actual temperature difference, your likely better hydration, and your likely more modest attire protecting you).
However…
The reason it is advisable to wear sunscreen in winter is not generally about sunburn, and is rather more about long-term cumulative skin damage (ranging from accelerated aging to cancer) caused by the UV rays—specifically, mostly UVA rays, since UVB rays (with their higher energy but shorter wavelength) have nearly all been blocked by the atmosphere.
Here’s a good explainer of that from the American Cancer Society:
UV (Ultraviolet) Radiation and Cancer Risk
👆 this may seem like a no-brainer, but there’s a lot explained here that demystifies a lot of things, covering ionizing vs non-ionizing radiation, x-rays and gamma-rays, the very different kinds of cancer caused by different things, and what things are dangerous vs which there’s no need to worry about (so far as best current science can say, at least).
Consequently: yes, if you value your skin health and avoidance of cancer, wearing sunscreen when out even in the winter is a good idea. Especially if your phone’s weather app says the UV index is “moderate” or above, but even if it’s “low”, it doesn’t hurt to include it as part of your skincare routine.
But what if sunscreens are dangerous?
Firstly, not all sunscreens are created equal:
Learn more: Who Screens The Sunscreens?
Secondly: consider putting on a protective layer of moisturizer first, and then the sunscreen on top. Bear in mind, this is winter we’re talking about, so you’re probably not going out in a bikini, so this is likely a face-neck-hands job and you’re done.
What about vitamin D?
Humans evolved to have more or less melanin in our skin depending on where we lived, and white people evolved to wring the most vitamin D possible out of the meagre sun far from the equator. Black people’s greater melanin, on the other hand, offers some initial protection against the sun (but any resultant skin cancer is then more dangerous than it would be for white people if it does occur, so please do use sunscreen whatever your skintone).
Nowadays many people live in many places which may or may not be the places we evolved for, and so we have to take that into account when it comes to sun exposure.
