In this week’s news roundup…
Children at highest risk for bird flu
When a new infectious disease comes out, we get used to hearing the usual refrain, “children, the elderly, those with compromised immune systems” are those considered at greatest risk, and therefore first in line for vaccines.
In this case, however, it seems that older adults appear to be rather more resilient to bird flu than children, and it’s noted that early childhood influenza exposure can elicit immune responses that last a lifetime. For those whose lifetime was not curtailed by the initial infection, that means they may enjoy extra defenses now.
You may be wondering whether this headline statement is just a hypothesis based on that, and no, it’s not. It’s a (albeit tentative, like most things in any emerging science, as responses to a novel infection will always be) conclusion based on blood samples from a little over 150 people born between 1927 and 2026 (so, quite a range), and examining the antibodies found therein; adults born prior to 1968 are the ones who are most likely to have been exposed to H1N1 or H2N2 in childhood, resulting in them now having antibodies that work against the H5N1 virus (but still, by all means please do take all sensible precautions anyway!):

GLP-1 Receptor Agonists? They work, but at what cost?
We’re not talking about the side effects this time! Nor even the “what happens if you stop taking it” problems.
Rather, the “cost” in this case is the literal financial cost; out of a selection of weight loss drugs examined, semaglutide (such as Ozempic and Wegovy) and tirzepatide (such as Zepbound and Eli Lilly) were the only ones deemed to not be cost-effective for patients:

Inflammation now, brittle bones later
Chronic inflammation is a root cause of many diseases (due in part to how it weakens the immune system, but also because of how the body functions so badly in general when it’s constantly at war with itself, as is the case in chronic inflammation), and it worsens many diseases that it doesn’t outright cause.
In this case, the new science is that chronic inflammation also makes changes to bone density over time.
Spoiler: the changes are not good changes
Furthermore, this holds true for young people also, not just people in the usual demographic that one would expect for brittle bones (especially: older women with untreated menopause, but also just anyone older than middle-aged in general, as most people start losing about 1% of bone density per year after their mid-30s).

Healthy Heart, Healthy Brain – by Dr. Bradley Bale & Dr. Amy Doneen
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 often written that “what’s good for your heart is good for your brain”, because the former feeds the latter and takes away detritus. You cannot have a healthy brain without a healthy heart.
This book goes into that in more detail than we have ever had room to here! This follows from their previous book “Beat The Heart Attack Gene”, but we’re jumping in here because that book doesn’t really contain anything not also included in this one.
The idea is the same though: it is the authors’ opinion that far too many interventions are occurring far too late, and they want to “wake everyone up” (including their colleagues in the field) to encourage earlier (and broader!) testing.
Fun fact: that also reminded this reviewer that she had a pending invitation for blood tests to check these kinds of things—phlebotomy appointment now booked, yay!
True the spirit of such exhortation to early testing, this book does include diagnostic questionnaires, to help the reader know where we might be at. And, interestingly, while the in-book questionnaire format of “so many points for this answer, so many for that one”, etc is quite normal, what they do differently in the diagnostics is that in cases of having to answer “I don’t know”, it assigns the highest-risk point value, i.e. the test will err on the side of assume the worst, in the case of a reader not knowing, for example, what our triglycerides are like. Which, when one thinks about it, is probably a very sensible reasoning.
There’s a lot of advice about specific clinical diagnostic tools and things to ask for, and also things that may raise an alarm that most people might overlook (including doctors, especially if they are only looking for something else at the time).
You may be wondering: do they actually give advice on what to actually do to improve heart and brain health, or just how to be aware of potential problems? And the answer is that the latter is a route to the former, and yes they do offer comprehensive advice—well beyond “eat fiber and get some exercise”, and even down to the pros and cons of various supplements and medications. When it comes to treating a problem that has been identified, or warding off a risk that has been flagged, the advice is a personalized, tailored, approach. Obviously there’s a limit to how much they can do that in the book, but even so, we see a lot of “if this then that” pointers to optimize things along the way.
The style is… a little salesy for this reviewer’s tastes. That is to say, while it has a lot of information of serious value, it’s also quite padded with self-congratulatory anecdotes about the many occasions the authors have pulled a Dr. House and saved the day when everyone else was mystified or thought nothing was wrong, the wonders of their trademarked methodology, and a lot of hype for their own book, as in, the book that’s already in your hands. Without all this padding, the book could have been cut by perhaps a third, if not more. Still, none of that takes away from the valuable insights that are in the book too.
Bottom line: if you’d like to have a healthier heart and brain, and especially if you’d like to avoid diseases of those two rather important organs, then this book is a treasure trove of information.

Does Ginseng Increase Testosterone Levels?
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 10almonds Subscribers!
Q: You talked about spearmint as reducing testosterone levels, what about ginseng for increasing them?
A: Hormones are complicated and often it’s not a simple matter of higher or lower levels! It can also be a matter of…
- how your body converts one thing into another
- how your body responds (or not) to something according to how the relevant hormone’s receptors are doing
- …and whether there’s anything else blocking those receptors.
All this to say: spearmint categorically is an anti-androgen, but the mechanism of action remains uncertain.
Panax ginseng, meanwhile, is one of the most well-established mysteries in herbal medicine.
Paradoxically, it seems to improve both male and female hormonal regulation, despite being more commonly associated with the former.
- It doesn’t necessarily increase or decrease testosterone or estrogen levels (but it can, even if indirectly)
- It does improve sexual function
- …and alleviates symptoms associated with conditions as varied as:
- Late-onset hypogonadism (common for men during the andropause)
- Benign prostate hyperplasia (again common for men during the andropause)
- …and also counteracts unwanted side-effects of finasteride. Finasteride is often taken by men as a hair loss remedy or, less often but critically, in the case of an enlarged prostate.
But it also…
- Alleviates symptoms of PCOS (polycystic ovary syndrome, which effects around 20% of women)
- May even be an effective treatment for PCOS (rat model only so far)
- It also may improve female reproductive fertility more generally (the studies are down to fruit flies now though)
Bottom line: Panax ginseng is popularly taken to improve natural hormone function, a task at which it appears to excel.
Scientists are still working out exactly how it does the many things it appears to do.
Progress has been made, and it clearly is science rather than witchcraft, but there are still far more unanswered questions than resolved ones!

Stop Tinnitus, & Improve Your Hearing By 130%
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.
Caveat: this will depend on the cause of your tinnitus, but there’s a quick diagnostic test first, and it’s for the most common kind 🙂
Step by step
To address noise in the ears (tinnitus) and improve hearing, start by identifying whether the issue is treatable. The diagnostic tests are:
- First, turn your head to the side, tilt it forward and backward, and observe changes in the noise. If the intensity changes, then the noise can be managed.
- Additionally, open and close your mouth, clenching and unclenching your teeth, and note any variations; this is about muscular tension affecting hearing.
- Finally, tilt your head downward—if the noise increases, it may mean it is a venous outflow disorder—there’s a fix for this, too.
Effective exercises focus on releasing tension and improving blood flow:
- Begin with the neck’s scalene muscles, located behind the sternocleidomastoid muscle.
- Massage these areas by moving your hands up and down and varying head positions slightly forward and backward.
- Repeat on both sides to enhance blood circulation and reduce auditory interference. Next, target the chewing muscles.
- Massage painful areas of the jaw and temporalis muscle in circular motions, working along and across the muscle fibers.
- Divide the temporalis muscle into sections and address each thoroughly to relieve tension and improve hearing.
- Mobilize the outer auditory passage by gently pulling the ear in all directions—starting with the earlobe, middle part, and upper ear.
- Focus on the cartilage above the lobe, moving it up and down to restore mobility and improve blood flow.
These exercises should fix the most common kind of tinnitus, and improve hearing—you’ll know quickly whether it works for you or not. Regular practice is required for sustained results, though.
For more on all this, plus visual demonstrations (e.g. how to find that temporalis muscle, etc), enjoy:

The Conquest of Happiness – by Bertrand Russell
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 we have all our physical needs taken care of, why are we often still not happy, and what can we do about that?
Mathematician, philosopher, and Nobel prizewinner Bertrand Russell has answers. And, unlike many of “the great philosophers”, his writing style is very clear and accessible.
His ideas are simple and practical, yet practised by few. Rather than taking a “be happy with whatever you have” approach, he does argue that we should strive to find more happiness in some areas and ways—and lays out guidelines for doing so.
Areas to expand, areas to pull back on, areas to walk a “virtuous mean”. Things to be optimistic about; things to not get our hopes up about.
Applying Russell’s model, there’s no more “should I…?” moments of wondering which way to jump.
Bottom line: if you’ve heard enough about “how to be happy” from wishy-washier sources, you might find the work of this famous logician refreshing.

Online Reaction Tests & Women’s Cognitive Health (Test Yours!)
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.
A team of researchers have looked into the use of online reaction tests (in which, for example, one clicks whenever a certain prompt is shown, or for more of a cognitive challenge, one presses a numerical key when the corresponding digit is shown) to cognitive health in women at different ages.
Why women? To quote the man who had the honor of being the first-listed author on the study (something that happens mysteriously often in science),
❝Women have long been under-represented in healthy aging research, despite making up more than half the population. We developed an easy way to measure cognitive function in the home, without the need for individuals to travel to clinics or receive home visits. Our research shows that testing of cognitive function in the home largely acceptable, easy and convenient❞
About that convenience: they used data from the UK Women’s Cohort Study, which involved over 35,000 British women, and then specifically focused on a follow-up study of 768 participants aged 48–85.
Of the two kinds of online reaction tests we described up top, they used the numerical kind. The participants also filled in a questionnaire about their personal traits (demographic data, mostly, though things like self-reported level of health literacy, and how they would rate their overall health).
What they found
The findings included:
- Younger women were more likely to participate, with participation rates dropping from 89% at age 45 to 44% at age 65.
- Each higher level of education increased the likelihood of volunteering by 7%.
- Women who rated themselves as having “high” intelligence were 19% more likely to participate than those who considered themselves of “average” intelligence.
- Women with lower self-reported health literacy made fewer errors, possibly due to taking longer to decide on answers—consistent with findings from older adults.
You can read the full paper itself here: Health literacy in relation to web-based measurement of cognitive function in the home: UK Women’s Cohort Study
Why this matters
We wrote, a little while ago, about the use of online games (of a specific kind) to improve cognitive function:
Synergistic Brain-Training: Let The Games Begin (But It Matters What Kind) ← the good news is, these are very accessible too
When it comes to rapid and/but correct reactions, this becomes really critical:
How (And Why) To Train Your Pre-Frontal Cortex ← Dr. Sandra Chapman advocates strongly for this, and it’s closely related to working memory and the ability to focus
Want to test yours?
Here are two ways to do it (now, for free, without needing to sign up for anything; the tests are right there on the page):
- HumanBenchmark.com’s Reaction Time Test ← this one’s just a “click when the red panel turns green” test, but the merit here is that it compares your scores to a very large dataset of other people
- Keypress Reaction Time Test ← this one’s the kind that was used in the study, and requires pressing the correct numerical key when the corresponding digit is shown on the screen. You can make it easier or harder by restricting or increasing the range of numbers it uses (default setting is to use the numbers 1, 2, 3, 4, 5, and 6)

Seniors: Improve Blood Flow & Circulation In Your Legs
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. Doug Weiss, a physiotherapist (and thus: a doctor of physical therapy), has advice on how and why to increase blood flow and circulation in your legs, keeping yourself healthier for longer and avoiding a lot of potential unpleasantries.
The exercises
The exercises here are not complex; they are as follows, and he suggests 3 sets of 10 reps of each, daily:
- Sitting ankle pumps: sitting on a chair or the edge of a bed, lift the toes up, then heels up, squeezing the muscles.
- Sitting knee extensions: sitting as before, kick one leg up until knee is straight, then switch legs.
- Heel raises: standing this time, with a sturdy support such as a countertop, raise on toes as high as possible, then lower heels back to the ground
- Pillow squats: placing pillows on a chair, cross hands on chest, and simply stand up and sit down—similar to the “getting up off the floor without using your hands” exercise, but an easier version.
For visuals on these, and more details including the specific benefits of each, enjoy:
