Cori Lefkowith, of “Redefining Strength” and “Strong At Every Age” fame, is back to help us keep our hips in good order:
These tips don’t lie
It’s less about stretching, and more about range of motion and “use it or lose it”:
- Full range of motion in lifting exercises enhances joint mobility and stability, whereas strengthening muscles through a limited range of motion (e.g., half squats) can cause tightness.
- Lifting through a larger range of motion may result in faster strength gains too, so that’s a bonus.
- Customize your range of motion based on your body type and capability, but do try for what you reasonably can—don’t give up!
- Lower weights and focus on deeper movements like split squats or single-leg squats, but work up slowly if you have any difficulties to start with.
- Using exercises like the Bulgarian split squat and deficit split squat can improve hip mobility and strength (you’ll really need to see the video for this one)
- Fully controlling the range of motion is key to progress, even if it means going lighter; prioritize mobility over brute strength. Strength is good, but mobility is even more critical.
- Adding instability, such as raising the front foot in lunges, challenges muscles and increases mobility. Obviously, please be safe while doing so, and slowly increase the range of motion while maintaining control, avoiding reliance on momentum.
- Final tip that most don’t consider: try starting exercises from the bottom position to ensure proper form and muscle engagement!

A Planet of Viruses – by Carl Zimmer
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.
We’ve reviewed numerous books on the immune system before, and this one’s mostly not about that.
Instead, this one focuses on the viruses themselves, and the part they play in our world, for good and for ill. Popular awareness tends to focus on the ill, of course.
But, there’s a lot that viruses do for us too, including:
- Weak/harmless viruses that keep our immune systems on their toes and ready
- Bacteriophage viruses that kill and consume pathogens that, left unchecked, would do the same to us
- Endogenous retroviruses that have become symbiotic with the human organism, without which our species would quickly go extinct
He also talks about biological warfare, and how we cannot bury our heads in the sand by avoiding research on those grounds, because someone will always do it anyway, so (as the motto of the immune system itself might say), best to be prepared.
The author is a science journalist, by the way, and has no PhD, but does have a flock of Fellowships and assorted scientific awards and honors, so he appears to be doing good work so far as the scientific community is concerned.
Bottom line: if you’d like to know more about viruses than “they’re very small and can cause harm”, then this book will open a whole new world.

Big Think’s #1 Antidote To Aging
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.
Why This Video Is Important
A lot of what we talk about here at 10almonds is focused on healthy aging. We want you – our lovely readers – to not only live for a long time, but also be healthy enough to enjoy that “long time”.
We’ve talked about anything from Dr. Greger’s eight anti-aging interventions, to the specific benefits of resveratrol or metformin in combatting aging, to even reducing stress-induced aging.
So, why is this video important? It goes beyond just talking about what we know about living longer, but also focuses on how we should live longer; there’s a big difference between living a long life but never leaving your house vs. living a long life beyond your front door.
The Takeaways
The core message that Big Think wants to convey is that our lifestyle is our best bet in slowing the aging process. Our bodies are adaptive systems, responding positively to healthy lifestyle choices. They focus on exercise: regular physical activity increases healthspan, consequently extending lifespan.
A key takeaway is the difference between physical activity and exercise. While any movement counts as physical activity, exercise is a deliberate, health-focused activity. It benefits the brain by releasing growth factors that strengthen critical areas like the hippocampus and prefrontal cortex.
The video encourages embracing physical activity in any form available to you, from gardening to walking. The goal isn’t to hit a specific number of steps but to stay active in a way that suits your lifestyle.
Science may not solve death. Yet. But focusing on maintaining a healthy, functioning state for as long as possible is the real victory in the battle against aging. And, at the moment, exercise seems to be our best bet:

Signs Of Low Estrogen In Women: What Your Skin, Hair, & Nails Are 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.
Skin, hair, and nails are often thought of purely as a beauty thing, but in fact they can be indicative of a lot of other aspects of health. Dr. Andrea Suarez takes us through some of them in this video about the systemic (i.e., whole-body, not just related to sex things) effects of estrogen, and/or a deficiency thereof.
Beyond the cosmetic
Low estrogen levels are usual in women during and after untreated menopause, resulting in various changes in the skin, hair, and nails, that reflect deeper issues, down to bone health, heart health, brain health, and more. Since we can’t see our bones or hearts or brains without scans (or a serious accident/incident), we’re going to focus on the outward signs of estrogen deficiency.
Estrogen helps maintain healthy collagen production, skin elasticity, wound healing, and moisture retention, making it essential for youthful and resilient skin. Declining estrogen levels with menopause lead to a thinner epidermis, decreased collagen production, and more pronounced wrinkles. Skin elasticity also diminishes, which slows the skin’s ability to recover from stretching or deformation. Wound healing also becomes slower, increasing the risk of infections and extended recovery periods after injuries or surgeries—bearing in mind that collagen is needed in everything from our skin to our internal connective tissue (fascia) and joints and bones. So all those things are going to struggle to recover from injury (and surgery is also an injury) without it.
Other visible changes associated with declining estrogen include significant dryness as a result of reduced hyaluronic acid and glycosaminoglycan production, which are essential for moisture retention. The skin becomes more prone to irritation and increased water loss. Additionally, estrogen deficiency results in less resistance to oxidative stress, making the skin more susceptible to damage from environmental factors such as UV radiation and pollution, as well as any from-the-inside pollution that some may have depending on diet and lifestyle.
Acne and enlarged pores are associated with increased testosterone, but testosterone and estrogen are antagonistic in most ways, and in this case a decrease in estrogen will do the same, due increased unopposed androgen signaling affecting the oil glands. The loss of supportive collagen also causes the skin around pores to lose structure, making them appear larger. The reduction in skin hydration further exacerbates the visibility of pores and can contribute to the development of blackheads due to abnormal cell turnover.
Blood vessel issues tend to arise as estrogen levels drop, leading to a reduction in angiogenesis, i.e. the formation and integrity of blood vessels. This results in more fragile and leaky blood vessels, making the skin more prone to bruising, especially on areas frequently exposed to the sun, such as the backs of the hands. This weakened vasculature also further contributes to the slower wound healing that we talked about, due to less efficient delivery of growth factors.
Hair and nail changes often accompany estrogen deficiency. Women may notice hair thinning, increased breakage, and a greater likelihood of androgenic alopecia. The texture of the hair can change, becoming more brittle. Similarly, nails can develop ridges, split more easily, and become more fragile due to reduced collagen and keratin production, which also affects the skin around the nails.
As for what to do about it? Management options for estrogen-deficient skin include:
- Bioidentical hormone replacement therapy (HRT), which can improve skin elasticity, boost collagen production, and reduce dryness and fragility, as well as addressing the many more serious internal things that are caused by the same deficiency as these outward signs.
- Low-dose topical estrogen cream, which can help alleviate skin dryness and increase skin strength, won’t give the systemic benefits (incl. to bones, heart, brain, etc) that only systemic HRT can yield.
- Plant-based phytoestrogens, which are not well-evidenced, but may be better than nothing if nothing is your only other option. However, if you are taking anything other form of estrogen, don’t use phytoestrogens as well, or they will compete for estrogen receptors, and do the job not nearly so well while impeding the bioidentical estrogen from doing its much better job.
And for all at any age, sunscreen continues to be one of the best things to put on one’s skin for general skin health, and this is even more true if running low on estrogen.

Stick with It – by Dr. Sean Young
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.
Most of us know the theory when it comes to building new habits and/or replacing old ones, and maybe we even implement those ideas. So why is our success rate still not as high as we think it should be?
Dr. Sean Young is here to do science to it!
This book comes with advice and explanations that rely a lot less on “that sounds reasonable” and a lot more on “in this recent high-quality study, researchers found…”
And, at 10almonds, we love that. We’re all for trying new things that sound reasonable in general… but we definitely prefer when there’s a stack of solid science to point to, and that’s the kind of thing we recommend!
Dr. Young is big on using that science to find ways to trick our brains and get them working the way we want.
Each chapter has lots of science, lots of explanations, and lots of actionable step-by-step advice.
Bottom line: if you’re all over “Atomic Habits”, this one’s the science-based heavy-artillery for your practical neurohacking.

CBD Oil
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.
Q&A with the 10almonds Team
Q: Very interested in this article on CBD oil in the states. hope you do another one in the future with more studies done on people and more information on what’s new as far as CBD oil goes
A: We’re glad you enjoyed it! We’ll be sure to revisit CBD in the future—partly because it was a very popular article, and partly because, as noted, there is a lot going on there, research-wise!
And yes, we prefer human studies rather than mouse/rat studies where possible, too, and try to include those where we find them. In some cases, non-human animal studies allow us to know things that we can’t know from human studies… because a research institution’s ethics board will greenlight things for mice that it’d never* greenlight for humans.
Especially: things that for non-human animals are considered “introduction of external stressors” while the same things done to humans would be unequivocally called “torture”.
Animal testing in general is of course a moral quagmire, precisely because of the suffering it causes for animals, while the research results (hopefully) can be brought to bear to reduce to suffering of humans. We’re a health and productivity newsletter, not a philosophical publication, but all this to say: we’re mindful of such too.
And yes, we agree, when studies are available on humans, they’re always going to be better than the same study done on mice and rats.
As a topical aside, did you know there’s a monument to laboratory mice and all they’ve (however unintentionally) done for us?
❝The quirky statue depicts an anthropomorphic mouse as an elderly woman, complete with glasses balanced atop its nose. Emerging from two knitting needles in its hands is the recognizable double-helix of a strand of DNA.❞

Pineapple vs Passion Fruit – Which is Healthier?
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.
Our Verdict
When comparing pineapple to passion fruit, we picked the passion fruit.
Why?
Both are certainly great, and both have won their respective previous comparisons! And this one’s close:
In terms of macros, passion fruit has about 4x the protein, nearly 2x the carbs, and more than 7x the fiber. So, this one’s a clear and overwhelming win for passion fruit.
Vitamins are quite close; pineapple has more of vitamins B1, B5, B6, B9, and C, while passion fruit has more of vitamins A, B2, B3, and choline. So, a 5:4 marginal win for pineapple.
When it comes to minerals, pineapple has more calcium, copper, manganese, and zinc, while passion fruit has more iron, manganese, phosphorus, potassium, and selenium. Superficially, this would be a 5:5 tie, but looking at the numbers, passion fruit’s margins of difference are much greater, which means it gives the better overall mineral coverage, and thus wins the category.
Looking at polyphenols, pineapple wins this category with its variety of lignans, while passion fruit has just secoisolariciresinol, of which pineapple has more anyway. Plus, not a polyphenol but doing much of the same job of same, pineapple has bromelain, which is unique to it. So pineapple wins on the phytochemicals reckoning.
Adding up the sections and weighting them for importance (e.g. what a difference it makes to health) and statistical relevance (e.g. greater or smaller margins of difference) makes for a nominal passion fruit win, but like we say, both of these fruits are great, so enjoy both!
