Premise: there are easily learnable techniques to rapidly (and greatly) improve one’s memory. We’ve touched on some of these methods before at 10almonds, but being a newsletter rather than a book, we’ve not been able to go as deeply into it as Horsley!
Your memory is far, far, far more powerful than you might realize, and this book will help unlock that. To illustrate…
Some of the book is given over to what are for most purposes “party tricks”, such as remembering pi to 10,000 places. Those things are fun, even if not as practical in today’s world of rarely needing to even know the actual digits of a phone number. However, they do also serve as a good example of just how much of “super memory” isn’t a matter of hard work, so much as being better organized about it.
Most of the book is focused on practical methods to improve the useful aspects of memory—including common mistakes!
If the book has any flaw it’s that the first chapter or so is spent persuading the reader of things we presumably already believe, given that we bought the book. For example, that remembering things is a learnable skill and that memory is functionally limitless. However, we still advise to not skip those chapters as they do contain some useful reframes as well.
Bottom line: if you read this book you will be astonished by how much you just learned—because you’ll be able to recall whole sections in detail! And then you can go apply that whatever areas of your life you wanted to when you bought the book.

The Salt Fix – by Dr. James DiNicolantonio
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.
This book has a bold premise: high salt consumption is not, as global scientific consensus holds, a serious health risk, but rather, as the title suggests, a health fix.
Dr. DiNicolantonio, a pharmacist, explains how “our ancestors crawled out of the sea millions of years ago and we still crave that salt”, giving this as a reason why we should consume salt ad libitum, aiming for 8–10g per day, and thereafter a fair portion of the book is given over to discussing how many health conditions are caused/exacerbated by sugar, and that therefore we have demonized the wrong white crystal (scientific consensus is that there are many white crystals that can cause us harm).
Indeed, sugar can be a big health problem, but reading it at such length felt a lot like when all a politician can talk about is how their political rival is worse.
A lot of the studies the author cites to support the idea of healthy higher salt consumption rates were on non-human animals, and it’s always a lottery as to whether those results translate to humans or not. Also, many of the studies he’s citing are old and have methodological flaws, while others we could not find when we looked them up.
One of the sources cited is “my friend Jose tried this and it worked for him”.
Bottom line: sodium is an essential mineral that we do need to live, but we are not convinced that this book’s ideas have scientific merit. But are they well-argued? Also no.

The Five Key Traits Of Healthy 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.
The Five Keys Of Aging Healthily
Image courtesy of Peter Prato. This is Dr. Daniel Levitin. He’s a neuroscientist, and his research focuses on aging, the brain, health, productivity, and creativity. Also music, and he himself is an accomplished musician also, but we’re not going to be focusing on that today.
We’re going to be looking at the traits that, according to science, promote healthy longevity in old age. In other words, the things that increase our healthspan, from the perspective of a cognitive scientist.
What does he say we should do?
Dr. Levitin offers us what he calls the “COACH” traits:
- Curiosity
- Openness
- Associations
- Conscientiousness
- Healthy practices
By “associations”, he means relationships. However, that would have made the acronym “CORCH”, and decisions had to be made.
Curiosity
Leonardo da Vinci had a list of seven traits he considered most important.
We’ll not go into those today (he is not our featured expert of the day!), but we will say that he agreed with Dr. Levitin on what goes at the top of the list: curiosity.
- Without curiosity, we will tend not to learn things, and learning things is key to keeping good cognitive function in old age
- Without curiosity, we will tend not to form hypotheses about how/why things are the way they are, so we will not exercise imagination, creativity, problem-solving, and other key functions of our brain
- Without curiosity, we will tend not to seek out new experiences, and consequently, our stimuli will be limited—and thus, so will our brains
Openness
Being curious about taking up ballroom dancing will do little for you, if you are not also open to actually trying it. But, openness is not just a tag-on to curiosity; it deserves its spot in its own right too.
Sometimes, ideas and opportunities come to us unbidden, and we have to be able to be open to those too. This doesn’t mean being naïve, but it does mean having at least a position of open-minded skepticism.
Basically, Dr. Levitin is asking us to be the opposite of the pejorative stereotype of “an old person stuck in their ways”.
Associations
People are complex, and so they bring complexities to our lives. Hopefully, positively stimulating ones. Without them to challenge us (again, hopefully in a positive way), we can get very stuck in a narrow field of experience.
And of course, having at least a few good friends has numerous benefits to health. There’s been a lot of research on this; 5 appears to be optimal.
- More than that, and the depth tends to tail off, and/or stresses ensue from juggling too many relationships
- Fewer than that, and we might be only a calendar clash away from loneliness
Friends provide social stimulation and mutual support; they’re good for our mental health and even our physiological immunity (counterintuitively, by means of shared germs).
And, a strong secure romantic relationship is something that has been found time and again to extend healthy life.
Note: by popular statistics, this benefit is conferred upon men partnered with women, men partnered with men, women partnered with women, but not women partnered with men.
There may be a causative factor that’s beyond the scope of this article which is about cognitive science, not feminism, but there could also be a mathematical explanation for this apparent odd-one-out:
Since women tend to live longer than men (who are also often older than their female partners), women who live the longest are often not in a relationship—precisely because they are widows. So these long-lived widows will tend to skew the stats, through no fault of their husbands.
On the flipside of this, for a woman to predecease her (statistically older and shorter-lived) husband will often require that she die quite early (perhaps due to accident or illness unrelated to age), which will again skew the stats to “women married to men die younger”, without anything nefarious going on.
Conscientiousness
People who score highly in the character trait “conscientiousness” will tend to live longer. The impact is so great, that a child’s scores will tend to dictate who dies in their 60s or their 80s, for example.
What does conscientiousness mean? It’s a broad character trait that’s scored in psychometric tests, so it can be things that have a direct impact on health, such as brushing one’s teeth, or things that are merely correlated, such as checking one’s work for typos (this writer does her best!).
In short, if you are the sort of person who attends to the paperwork for your taxes on time, you are probably also the sort of person who remembers to get your flu vaccination and cancer screening.
Healthy practices
This means “the usual things”, such as:
- Healthy diet (Mediterranean Diet consistently scores up top)
- Good exercise (especially the tendency to keep moving in general)
- Good sleep (7–9 hours, no compromises)
- Not drinking (or at least only very moderate consumption, but the only safe amount is zero)
- Not smoking (just don’t; there is no wiggle room on this one)

Goat Milk Greek Yogurt vs Almond Milk Greek Yogurt – 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 goat milk yogurt to almond milk yogurt, we picked the almond milk yogurt.
Why?
Surprised? Honestly, we were too!
Much as we love almonds, we were fully expecting to write about how they’re very close in nutritional value, but the dairy yogurt has more probiotics, but no, as it turns out when we looked into them, they’re quite comparable in that regard.
It’s easy to assume “goat milk yogurt is more natural and therefore healthier”, but in both cases, it was a case of taking a fermentable milk, and fermenting it (an ancient process). “But almond milk is a newfangled thing”, well, new-ish…
So what was the deciding factor?
In this case, the almond milk yogurt has about twice the protein per (same size) serving, compared to the goat milk; all the other macros are about the same, and the micronutrients are similar. Like many plant-based milks and yogurts, this one is fortified with calcium and vitamin D, so that wasn’t an issue either.
In short: the only meaningful difference was the protein, and the almond came out on top.
However!
The almond came out on top only because it is strained; this can be done (or not) with any kind of yogurt, be it from an animal or a plant.
In other words: if it had been different brands, the goat milk yogurt could have come out on top!
The take-away idea here is: always read labels, because as you’ve just seen, even we can get surprised sometimes!
seriously if you only remember one thing from this today, make it the above
Other thing worth mentioning: yogurts, and dairy products in general, are often made with common allergens (e.g. dairy, nuts, soy, etc). So if you are allergic or intolerant, obviously don’t choose the one to which you are allergic or intolerant.
That said… If you are lactose-intolerant, but not allergic, goat’s milk does have less lactose than cow’s milk. But of course, you know your limits better than we can in this regard.
Want to try some?
Amazon is not coming up with the goods for this one (or anything even similar, at time of writing), so we recommend trying your local supermarket (and reading labels, because products vary widely!)
What you’re looking for (be it animal- or plant-based):
- Live culture probiotic bacteria
- No added sugar
- Minimal additives in general
- Lastly, check out the amounts for protein, calcium, vitamin D, etc.
Enjoy!

7 Essential Devices For Hand Arthritis: Regain Control of Your Life
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. Diana Girnita is a double board-certified physician in rheumatology and internal medicine. With a PhD in immunology (on top of her MD), and training at Harvard and top universities, she founded Rheumatologist OnCall, offering integrative medicine to broaden rheumatology access. Here’s what she has to say about things that make life easier:
Get your hands on these…
The seven devices that Dr. Girnita recommends are:
- Hand grip strengthener: helps build grip strength with a spring-loaded mechanism. Regular use can improve strength and reduce pain.
- Finger exerciser: different device; similar principle: it strengthens hand and finger muscles using resistance, enhancing hand function.
- Moisturizing paraffin bath: a heated paraffin wax bath that soothes hands, providing heat therapy and moisturizing the skin.
- Weighted silverware: weighted utensils (knives, forks, spoons) make gripping easier and provide stability for eating.
- Foam tubing grips: foam covers to make kitchen tools, toothbrushes, and hairbrushes easier to grip.
- Electric can-opener: reduces strain in opening cans, making meal preparation more accessible.
- Compression gloves: provide gentle compression to reduce swelling and pain, improving hand flexibility and circulation.
- Door knob cover grips: make it easier to turn doorknobs by providing a larger surface to grip.
- Wider-grip pens: ergonomically designed pens with a larger diameter and softer grip reduce hand strain while writing.
This writer, who does not have arthritis but also does not have anything like the grip strength she used to, also recommends a jar opener like this one.
As a bonus, if you spend a lot of time writing at a computer, an ergonomic split keyboard like this one goes a long way to avoiding carpal tunnel syndrome, and logically must be better for arthritis than a regular keyboard; another excellent thing to have (that again this writer uses and swears by) is an ergonomic vertical mouse like this one (aligns the wrist bones correctly; the “normal” horizontal version is woeful for the carpal bones). These things are both also excellent to help avoid worsening peripheral neuropathy (something that troubles this writer’s wrists if she’s not careful, due to old injuries there).

The Lies That Depression Tells Us
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.
In this short (6:42) video, psychiatrist Dr. Tracey Marks talks about 8 commonly-believed lies that depression often tells us. They are:
- “I don’t measure up”
- “No one cares about me”
- “I’m better off alone”
- “No one understands”
- “It’s all my fault”
- “I have no reason to be depressed”
- “Nothing matters”
- “I’ll never get better”
Some of these can be reinforced by people around us; it’s easy to believe that “no one understands” if for example the few people we interact with the most don’t understand, or that “I have no reason to be depressed” if people try to cheer you up by pointing out your many good fortunes.
The reality, of course, is that depression is a large, complex, and many-headed beast, with firm roots in neurobiology.
There are things we can do that may ameliorate it… But they also may not, and sometimes life is just going to suck for a while. That doesn’t mean we should give up (that, too, is depression lying to us, per “I’ll never get better”), but it does mean that we should not be so hard on ourselves for not having “walked it off” the way one might “just walk off” a broken leg.
Oh, you can’t “just walk off” a broken leg? Well then, perhaps it’s not surprising if we don’t “just think off” a broken brain, either. The brain can rebuild itself, but that’s a slow process, so buckle in:

‘Sleep tourism’ promises the trip of your dreams. Beyond the hype plus 5 tips for a holiday at home
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.
Imagine arriving at your hotel after a long flight and being greeted by your own personal sleep butler. They present you with a pillow menu and invite you to a sleep meditation session later that day.
You unpack in a room kitted with an AI-powered smart bed, blackout shades, blue light-blocking glasses and weighted blankets.
Holidays are traditionally for activities or sightseeing – eating Parisian pastry under the Eiffel tower, ice skating at New York City’s Rockefeller Centre, lying by the pool in Bali or sipping limoncello in Sicily. But “sleep tourism” offers vacations for the sole purpose of getting good sleep.
The emerging trend extends out of the global wellness tourism industry – reportedly worth more than US$800 billion globally (A$1.2 trillion) and expected to boom.
Luxurious sleep retreats and sleep suites at hotels are popping up all over the world for tourists to get some much-needed rest, relaxation and recovery. But do you really need to leave home for some shuteye?
RossHelen/Shutterstock Not getting enough
The rise of sleep tourism may be a sign of just how chronically sleep deprived we all are.
In Australia more than one-third of adults are not achieving the recommended 7–9 hours of sleep per night, and the estimated cost of this inadequate sleep is A$45 billion each year.
Inadequate sleep is linked to long-term health problems including poor mental health, heart disease, metabolic disease and deaths from any cause.
Can a fancy hotel give you a better sleep?
Many of the sleep services available in the sleep tourism industry aim to optimise the bedroom for sleep. This is a core component of sleep hygiene – a series of healthy sleep practices that facilitate good sleep including sleeping in a comfortable bedroom with a good mattress and pillow, sleeping in a quiet environment and relaxing before bed.
The more people follow sleep hygiene practices, the better their sleep quality and quantity.
When we are staying in a hotel we are also likely away from any stressors we encounter in everyday life (such as work pressure or caring responsibilities). And we’re away from potential nighttime disruptions to sleep we might experience at home (the construction work next door, restless pets, unsettled children). So regardless of the sleep features hotels offer, it is likely we will experience improved sleep when we are away.
Being away from home also means being away from domestic disruptions. Makistock/Shutterstock What the science says about catching up on sleep
In the short-term, we can catch up on sleep. This can happen, for example, after a short night of sleep when our brain accumulates “sleep pressure”. This term describes how strong the biological drive for sleep is. More sleep pressure makes it easier to sleep the next night and to sleep for longer.
But while a longer sleep the next night can relieve the sleep pressure, it does not reverse the effects of the short sleep on our brain and body. Every night’s sleep is important for our body to recover and for our brain to process the events of that day. Spending a holiday “catching up” on sleep could help you feel more rested, but it is not a substitute for prioritising regular healthy sleep at home.
All good things, including holidays, must come to an end. Unfortunately the perks of sleep tourism may end too.
Our bodies do not like variability in the time of day that we sleep. The most common example of this is called “social jet lag”, where weekday sleep (getting up early to get to work or school) is vastly different to weekend sleep (late nights and sleep ins). This can result in a sleepy, grouchy start to the week on Monday. Sleep tourism may be similar, if you do not come back home with the intention to prioritise sleep.
So we should be mindful that as well as sleeping well on holiday, it is important to optimise conditions at home to get consistent, adequate sleep every night.
Good sleep hygiene doesn’t require a passport. Maridav/Shutterstock 5 tips for having a sleep holiday at home
An AI-powered mattress and a sleep butler at home might be the dream. But these features are not the only way we can optimise our sleep environment and give ourselves the best chance to get a good night’s sleep. Here are five ideas to start the night right:
1. avoid bright artificial light in the evening (such as bright overhead lights, phones, laptops)
2. make your bed as comfortable as possible with fresh pillows and a supportive mattress
3. use black-out window coverings and maintain a cool room temperature for the ideal sleeping environment
4. establish an evening wind-down routine, such as a warm shower and reading a book before bed or even a “sleepy girl mocktail”
5. use consistency as the key to a good sleep routine. Aim for a similar bedtime and wake time – even on weekends.
