Dr. Doug Lucas is a dual board-certified physician specializing in optimizing healthspan and bone health for women experiencing osteoporosis, perimenopause, and menopause. Here, he talks weight vests:
Worth the weight?
Dr. Lucas cites “Wolf’s Law”—bones respond to stress. A weighted vest adds stress, to help build bone density. That said, they may not be suitable for everyone (for example, in cases of severe osteoporosis or a recent vertebral fracture).
He also cites some studies:
- Erlanger Fitness Study (2004): participants with a weighted vest maintained or improved bone density compared to a control group, but there was no group with exercise alone, making it unclear if the vest itself had the biggest impact.
- Newer studies (2016, 2017): showed improved outcomes for groups wearing a weighted vest, but again lacked an exercise-only group for comparison.
- 2012 study: included three groups (control, weighted vest, exercise only). Results showed no significant bone density difference between vest and exercise-only groups, though the vest group showed better balance and motor control.
Dr. Lucas concludes that weighted vests are a useful tool while nevertheless not being a magic bullet for bone health. In other words, they can complement exercise but you will also be fine without. If you do choose to level-up your exercise by using a weight vest, then starting with 5–10% of body weight in a vest is often recommended, but it depends on individual circumstances. If in doubt, start low and build up. Wearing the vest for daily activities can be effective, but improper use (awkward positions or improper impact training) can increase injury risk, so do be careful with that.

Life After Death? (Your Life; A Loved One’s Death)
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.
The Show Must Go On
We’ve previously written about the topics of death and dying. It’s not cheery, but it is important to tackle.
Sooner is better than later, in the case of:
Preparations For Managing Your Own Mortality
And for those who are left behind, of course it is hardest of all:
What Grief Does To Your Body (And How To Manage It)
But what about what comes next? For those who are left behind, that is.
Life goes on
In cases when the death is that of a close loved one, the early days after death can seem like a surreal blur. How can the world go ticking on as normal when [loved one] is dead?
But incontrovertibly, it does, so we can only ask again: how?
And, we get to choose that, to a degree. The above-linked article about grief gives a “101” rundown, but it’s (by necessity, for space) a scant preparation for one of the biggest challenges in life that most of us will ever face.
For many people, processing grief involves a kind of “saying goodbye”. For others, it doesn’t, as in the following cases of grieving the loss of one’s child—something no parent should ever have to face, but it happens:
Dr. Ken Druck | The Love That Never Dies
(with warning, the above article is a little heavy)
In short: for those who choose not to “say goodbye” in the case of the death of a loved one, it’s more often not a case of cold neglect, but rather the opposite—a holding on. Not in the “denial” sense of holding on, but rather in the sense of “I am not letting go of this feeling of love, no matter how much it might hurt to hold onto; it’s all I have”.
What about widows, and love after death?
Note: we’ll use the feminine “widow” here as a) it’s the most common and b) most scientific literature focuses on widows, but there is no reason why most of the same things won’t also apply to widowers.
We say “most”, as society does tend to treat widows and widowers differently, having different expectations about a respectful mourning period, one’s comportment during same, and so on.
As an aside: most scientific literature also assumes heterosexuality, which is again statistically reasonable, and for the mostpart the main difference is any extra challenges presented by non-recognition of marriages, and/or homophobic in-laws. But otherwise, grief is grief, and as the saying goes, love is love.
One last specificity before we get into the meat of this: we are generally assuming marriages to be monogamous here. Polyamorous arrangements will likely sidestep most of these issues completely, but again, they’re not the norm.
Firstly, there’s a big difference between remarrying (or similar) after being widowed, and remarrying (or similar) after a divorce, and that largely lies in the difference of how they begin. A divorce is (however stressful it may often be) more often seen as a transition into a new period of freedom, whereas bereavement is almost always felt as a terrible loss.
The science, by the way, shows the stats for this; people are less likely to remarry, and slower to remarry if they do, in instances of bereavement rather than divorce, for example:
Timing of Remarriage Among Divorced and Widowed Parents
Love after death: the options
For widows, then, there seem to be multiple options:
- Hold on to the feelings for one’s deceased partner; never remarry
- Grieve, move on, find new love, relegating the old to history
- Try to balance the two (this is tricky but can be done*)
*Why is balancing the two tricky, and how can it be done?
It’s tricky because ultimately there are three people’s wishes at hand:
- The deceased (“they would want me to be happy” vs “I feel I would be betraying them”—which two feelings can also absolutely come together, by the way)
- Yourself (whether you actually want to get a new partner, or just remain single—this is your 100% your choice either way, and your decision should be made consciously)
- The new love (how comfortable are they with your continued feelings for your late love, really?)
And obviously only two of the above can be polled for opinions, and the latter one might say what they think we want to hear, only to secretly and/or later resent it.
One piece of solid advice for the happily married: talk with your partner now about how you each would feel about the other potentially remarrying in the event of your death. Do they have your pre-emptive blessing to do whatever, do you ask a respectable mourning period first (how long?), would the thought just plain make you jealous? Be honest, and bid your partner be honest too.
One piece of solid advice for everyone: make sure you, and your partner(s), as applicable, have a good emotional safety net, if you can. Close friends or family members that you genuinely completely trust to be there through thick and thin, to hold your/their hand through the emotional wreck that will likely follow.
Because, while depression and social loneliness are expected and looked out for, it’s emotional loneliness that actually hits the hardest, for most people:
Longitudinal Examination of Emotional Functioning in Older Adults After Spousal Bereavement
…which means that having even just one close friend or family member with whom one can be at one’s absolute worst, express emotions without censure, not have to put on the socially expected appearance of emotional stability… Having that one person (ideally more, but having at least one is critical) can make a huge difference.
But what if a person has nobody?
That’s definitely a hard place to be, but here’s a good starting point:

What Your Skin Is Trying To Tell You
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.
Dr. Andrea Suarez, dermatologist, gives us the inside info:
Most people don’t think much about it, but…
You might want to recognize these patterns of symptoms, because often there’s an easy fix, and sometimes there’s something very important you should know:
- Aracked corners of your mouth (angular cheilitis): redness, scaling, and painful cracks are most commonly caused by saliva pooling from lip licking, drooling, gum chewing, or poorly fitted dentures; candida yeast can overgrow in this moist environment, while nutritional deficiencies such as B vitamins or iron are less common causes; management focuses on barrier protection with petroleum jelly (e.g. Vaseline) or zinc oxide (e.g. Sudocrem), antifungals if there’s yeast*, and avoiding behaviors that increase saliva exposure.
- *Or rather, if there’s a yeast overgrowth. Because one thing about yeast is that there’s always yeast, unless you have gone to truly extreme lengths to not have yeast, and you did that right now, and/or in a clean-room that you are still in. Because otherwise, 10 minutes later, you’ll have picked up some yeast again from the environment.
- Dry, cracked heels: usually result from thick skin on your soles drying out due to low humidity, barefoot walking, aging, or menopause-related lipid loss, not diet or nutritional deficiencies; consistent barrier repair with ointments, keratolytic ingredients like urea, salicylic acid, or alpha hydroxy acids, wearing socks, and sealing painful cracks to allow healing are key for this one.
- Acanthosis nigricans: darker, thickened skin on your neck, underarms, groin, face, or hands is a sign of skin thickening rather than pigmentation and serves as a warning sign of insulin resistance; topical treatments alone are ineffective unless the underlying metabolic issue is addressed.
- Asteatotic eczema (eczema craquelé): very dry, cracked skin with a “dry riverbed” appearance, commonly on your lower legs in older adults, often caused (counterintuitively) by overbathing, long hot showers, and excessive soap use; improvement comes from shortening showers, avoiding soap on your legs, using petroleum jelly initially, then urea or ammonium lactate moisturizers, and increasing ambient humidity.
- Sudden oilier skin: rapid increases in oiliness are driven by hormonal changes such as puberty, pregnancy, postpartum shifts, starting or stopping birth control, perimenopause, menopause, testosterone therapy (but not estradiol/progesterone therapy) or certain steroids; excess oil can worsen acne and yeast-related conditions, so gentle cleansing and oil removal help, while aggressive exfoliation and overwashing can damage your skin barrier, so do still try to go easy on that.
- allergic contact dermatitis from shampoo or conditioner: itchy, red, or oozing rashes behind your ears, along your hairline, neck, or eyelids often follow a rinse-off pattern linked to allergens in hair products, commonly fragrances, preservatives like methylisothiazolinone, cocamidopropyl betaine, and often even some essential oils; patch testing is needed to identify and avoid the trigger.

The Brain-Skin Doctor

Of Brains And Breakouts
Today’s spotlight is on Dr. Claudia Aguirre. She’s a molecular neuroscientist, and today she’s going to be educating us about skin.
What? Why?
When we say “neuroscience”, we generally think of the brain. And indeed, that’s a very important part of it.
We might think about eyes, which are basically an extension of the brain.
We don’t usually think about skin, which (just like our eyes) is constantly feeding us a lot of information about our surroundings, via a little under three million nerve endings. Guess where the other ends of those nerves lead!
There’s a constant two-way communication going on between our brain and our skin.
What does she want us to know?
Psychodermatology
The brain and the skin talk to each other, and maladies of one can impact the other:
- Directly, e.g. stress prompting skin breakouts (actually this is a several-step process physiologically, but for the sake of brevity we’ll call this direct)
- Indirectly, e.g. nervous disorders that result in people scratching or picking at their skin, which prompts a whole vicious cycle of one thing making the other worse
Read more: Psychodermatology: The Brain-Skin Connection
To address both kinds of problems, clearly something beyond moisturizer is needed!
Mindfulness (meditation and beyond)
Mindfulness is a well-evidenced healthful practice for many reasons, and Dr. Aguirra argues the case for it being good for our skin too.
As she points out,
❝Cultural stress and anxiety can trigger or aggravate many skin conditions—from acne to eczema to herpes, psoriasis, and rosacea.
Conversely, a disfiguring skin condition can trigger stress, anxiety, depression, and even suicide.
Chronic, generalized anxiety can create chronic inflammation and exacerbate inflammatory skin conditions, such as those I mentioned previously.
Chronic stress can result in chronic anxiety, hypervigilance, poor sleep, and a whole cascade of effects resulting in a constant breakdown of tissues and organs, including the skin.❞
So, she recommends mindfulness-based stress reduction (MBSR), for the above reasons, along with others!
Read more: Mind Matters
How to do it: No-Frills, Evidence-Based Mindfulness
And as for “and beyond?”
Do you remember in the beginning of the pandemic, when people were briefly much more consciously trying to avoid touching their faces so much? That, too, is mindfulness. It may have been a stressed and anxious mindfulness for many*, but mindfulness nonetheless.
*which is why “mindfulness-based stress reduction” is not a redundant tautology repeated more than once unnecessarily, one time after another 😉
So: do try to keep aware of what you are doing to your skin, and so far as is reasonably practicable, only do the things that are good for it!
The skin as an endocrine organ
Nerves are not the only messengers in the body; hormones do a lot of our body’s internal communication too. And not just the ones everyone remembers are hormones (e.g. estrogen, testosterone, although yes, they do both have a big impact on skin too), but also many more, including some made in the skin itself!
Dr. Aguirra gives us a rundown of common conditions, the hormones behind them, and what we can do if we don’t want them:
Read more: Rethinking The Skin As An Endocrine Organ
Take-away advice:
For healthy skin, we need to do more than just hydrate, get good sleep, have good nutrition, and get a little sun (but not too much).
- We should also practice mindfulness-based stress reduction, and seek help for more serious mental health issues.
- We should also remember the part our hormones play in our skin, and not just the obvious ones.
Did you know that vitamin D is also a hormone, by the way? It’s not the only hormone at play in your skin by a long way, but it is an important one:

Genius Gut – by Dr. Emily Leeming
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.
When it comes to the gut-brain information interchange, 90% of it is the gut talking to the brain (the brain is a good listener). As such, one of the best things we can do for our brain is ensure our gut has good things to say.
Dr. Leeming talks us through doing a quick initial assessment to judge the general goodness/badness of our current gut situation (based on output, not input, so it’s about the actual goodness/badness, not what we expect it should be), before going on to explain a lot of the anatomy and physiology at hand.
The hacks themselves may be, in their titles, things you already know—but where the real value of this book lies is in all the data and science collated under each of those hacks, allowing the reader to optimize everything rather than just guessing. Which can mean optimize by doing things as close to perfectly as possible, or it can mean optimize by doing/using the things that get the best results for the minimum effort. It’s up to you!
The style is very casual and friendly, even conversational, while not skimping on science (and indeed, citations are frequently provided for such).
Bottom line: if you’d like to improve your gut health, especially with the goal of improving your brain health, this is an excellent book for that.

See what other 10almonds subscribers are asking!
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!
Q: I would be interested in learning more about collagen and especially collagen supplements/powders and of course if needed, what is the best collagen product to take. What is collagen? Why do we need to supplement the collagen in our body? Thank you PS love the information I am receiving in the news letters. Keep it up
We’re glad you’re enjoying them! Your request prompted us to do our recent Research Review Monday main feature on collagen supplementation—we hope it helped, and if you’ve any more specific (or other) question, go ahead and let us know! We love questions and requests
Q: Great article about the health risks of salt to organs other than the heart! Is pink Himalayan sea salt, the pink kind, healthier?
Thank you! And, no, sorry. Any salt that is sodium chloride has the exact same effect because it’s chemically the same substance, even if impurities (however pretty) make it look different.
If you want a lower-sodium salt, we recommend the kind that says “low sodium” or “reduced sodium” or similar. Check the ingredients, it’ll probably be sodium chloride cut with potassium chloride. Potassium chloride is not only not a source of sodium, but also, it’s a source of potassium, which (unlike sodium) most of us could stand to get a little more of.
For your convenience: here’s an example on Amazon!
Bonus: you can get a reduced sodium version of pink Himalayan salt too!
Q: Can you let us know about more studies that have been done on statins? Are they really worth taking?
That is a great question! We imagine it might have been our recent book recommendation that prompted it? It’s quite a broad question though, so we’ll do that as a main feature in the near future!
Q: Is MSG healthier than salt in terms of sodium content or is it the same or worse?
Great question, and for that matter, MSG itself is a great topic for another day. But your actual question, we can readily answer here and now:
- Firstly, by “salt” we’re assuming from context that you mean sodium chloride.
- Both salt and MSG do contain sodium. However…
- MSG contains only about a third of the sodium that salt does, gram-for-gram.
- It’s still wise to be mindful of it, though. Same with sodium in other ingredients!
- Baking soda contains about twice as much sodium, gram for gram, as MSG.
Wondering why this happens?
Salt (sodium chloride, NaCl) is equal parts sodium and chlorine, by atom count, but sodium’s atomic mass is lower than chlorine’s, so 100g of salt contains only 39.34g of sodium.
Baking soda (sodium bicarbonate, NaHCO₃) is one part sodium for one part hydrogen, one part carbon, and three parts oxygen. Taking each of their diverse atomic masses into account, we see that 100g of baking soda contains 27.4g sodium.
MSG (monosodium glutamate, C₅H₈NO₄Na) is only one part sodium for 5 parts carbon, 8 parts hydrogen, 1 part nitrogen, and 4 parts oxygen… And all those other atoms put together weigh a lot (comparatively), so 100g of MSG contains only 12.28g sodium.
Q: Thanks for the info about dairy. As a vegan, I look forward to a future comment about milk alternatives
Thanks for bringing it up! What we research and write about is heavily driven by subscriber feedback, so notes like this really help us know there’s an audience for a given topic!
We’ll do a main feature on it, to do it justice. Watch out for Research Review Monday!

Healthy Longevity As A Lifestyle Choice
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.
7 Keys To Healthy Longevity
This is Dr. Luigi Fontana. He’s a research professor of Geriatrics & Nutritional Science, and co-director of the Longevity Research Program at Washington University in St. Louis.
What does he want us to know?
He has a many-fold approach to healthy longevity, most of which may not be news to you, but you might want to prioritize some things:
Consider caloric restriction with optimal nutrition (CRON)
This is about reducing the metabolic load on your body, which frees up bodily resources for keeping yourself young.
Keeping your body young and healthy is your body’s favorite thing to do, but it can’t do that if it never gets a chance because of all the urgent metabolic tasks you’re giving it.
If CRON isn’t your thing (isn’t practicable for you, causes undue suffering, etc) then intermittent fasting is a great CR mimetic, and he recommends that too. See also:
- Is Cutting Calories The Key To Healthy Long Life?
- Fasting Without Crashing? We Sort The Science From The Hype
Keep your waistline small
Whichever approach you prefer to use to look after your metabolic health, keeping your waistline down is much more important for health than BMI.
Specifically, he recommends keeping it:
- under 31.5” for women
- under 37” for men
The disparity here is because of hormonal differences that influence both metabolism and fat distribution.
Exercise as part of your lifestyle
For Dr. Fontana, he loves mountain-biking (this writer could never!) and weight-lifting (also not my thing). But what’s key is not the specifics, but what’s going on:
- Some kind of frequent movement
- Some kind of high-intensity interval training
- Some kind of resistance training
Frequent movement because our bodies are evolved to be moving more often than not:
The Doctor Who Wants Us To Exercise Less, & Move More
High-Intensity Interval Training because unlike most forms of exercise (which slow metabolism afterwards to compensate), it boosts metabolism for up to 2 hours after training:
How To Do HIIT (Without Wrecking Your Body)
Resistance training because strength (of muscles and bones) matters too:
Resistance Is Useful! (Especially As We Get Older)
Writer’s examples:
So while I don’t care for mountain-biking or weight-lifting, what I do is:
1) movement: walk (briskly!) everywhere and also use a standing desk
2) HIIT: 2-minute bursts of hindu squats and/or exercise bike sprints
3) resistance: pilates and other calisthenicsModeration is not key
Dr. Fontana advises that we do not smoke, and that we do not drink alcohol, for example. He also notes that just as the only healthy amount of alcohol is zero, less ultra-processed food is always better than more.
Maybe you don’t want to abstain completely, but mindful wilful consumption of something unhealthy is preferable to believing “moderate consumption is good for the health” and an unhealthy habit develops!
Greens and beans
Shocking absolutely nobody, Dr. Fontana advocates for (what has been the most evidence-based gold standard of healthy-aging diets for quite some years now) the Mediterranean diet.
See also: Four Ways To Upgrade The Mediterranean Diet ← this is about tweaking the Mediterranean diet per personal area of focus, e.g. anti-inflammatory bonus, best for gut, heart healthiest, and most neuroprotective.
Take it easy
Dr. Fontana advises us (again, with a wealth of evidence) Mindfulness-Based Stress Reduction, and to get good sleep.
Not shocked?
To quote the good doctor,
❝There are no shortcuts. No magic pills or expensive procedures can replace the beneficial effects of a healthy diet, exercise, mindfulness, or a regenerating night’s sleep.❞
Always a good reminder!
