Jim Kwik: from broken brain to brain coach
This is Jim Kwik. He suffered a traumatic brain injury as a small child, and later taught himself to read and write by reading comic books. He became fascinated with the process of learning, and in his late 20s he set up Kwik Learning, to teach accelerated learning in classrooms and companies, which he continued until 2009 when he launched his online learning platform. His courses have now been enjoyed by people in 195 countries.
So, since accelerated learning is his thing, you might wonder…
What does he have to share that we can benefit from in the next five minutes?
Three brain exercises to improve memory and concentration
A lot of problems we have with working memory are a case of executive dysfunction, but there are tricks we can use to get our brains into gear and make them cumulatively stronger:
First exercise
You can strengthen your corpus callosum (the little bridge between the two hemispheres of the brain) by performing a simple kinesiological exercise, such as alternating touching your left elbow to your right knee, and touching your right elbow to your left knee.
Do it for about a minute, but the goal here is not a cardio exercise, it’s accuracy!
You want to touch your elbow and opposite knee to each other as precisely as possible each time. Not missing slightly off to the side, not falling slightly short, not hitting it too hard.
Second exercise
Put your hands out in front of you, as though you’re about to type at a keyboard. Now, turn your hands palm-upwards. Now back to where they were. Now palm-upwards again. Got it? Good.
That’s not the exercise, the exercise is:
You’re now going to do the same thing, but do it twice as quickly with one hand than the other. So they’ll still be flipping to the same basic “beat”, put it in musical terms, the tempo on one hand will now be twice that of the other. When you get the hang of that, switch hands and do the other side.
This is again about the corpus callosum, but it’s now adding an extra level of challenge because of holding the two rhythms separately, which is also working the frontal lobe of the cerebral cortex.
The pre-frontal cortex in particular is incredibly important to executive function, self-discipline, and being able to “do” delayed gratification. So this exercise is really important!
Third exercise
This one works the same features of the brain, but most people find it harder. So, consider it a level-up on the previous:
Imagine there’s a bicycle wheel in front of you (as though the bike is facing you at chest-height). Turn the wheel towards you with your hands, one on each side.
Now, do the same thing, but each of your hands is going in the opposite direction. So one is turning the wheel towards you; the other is turning it away from you.
Now, do the same thing, but one hand goes twice as quickly as the other.
Switch sides.
Why is this harder for most people than the previous? Because the previous involved processing discrete (distinct from each other) movements while this one involves analog continuous movements.
It’s like reading an analog clock vs a digital clock, but while using both halves of your brain, your corpus callosum, your pre-frontal cortex, and the motor cortex too.

Tasty Tabbouleh with Tahini
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.
Tabbouleh is a salad, but it’s not “just a salad”. It’s a special kind of salad that’s as exciting for the tastebuds as it is healthy for the body and brain. Its core ingredients have been traditional for about a dozen generations, and seasonings are always a personal matter (not to mention that Lebanese tabbouleh-makers centuries ago might not have used miso and nooch, as we will today), but the overall feel of the Gestalt of tabbouleh seasonings remains the same, and this recipe is true to that.
You will need
For the tabbouleh:
- 1 cup bulgur wheat
- 1 cup plum tomatoes, chopped
- 1 cucumber, peeled and chopped (add the peel to a jug of water and put it in the fridge; this will be refreshing cucumber water later!)
- 1 cup chickpeas, cooked without salt
- 1/2 cup parsley, chopped
- 1/2 cup mint, chopped
- 2 spring onions, finely chopped
- 2oz fresh lemon juice
- 1 tsp white miso paste
- 1 tsp garlic powder
- 1 tsp ground cumin
- 1 tsp ground celery seeds
- 1 tsp ground nigella seeds
- 1 tsp ground black pepper
- 1 tsp MSG, or 1/2 tsp low sodium salt (you can find it in supermarkets, the sodium chloride is cut with potassium chloride to make it have less sodium and more potassium)
- 1 tbsp nutritional yeast (nooch), ground (it comes in flakes; you will have to grind it in a spice grinder or with a pestle and mortar)
For the tahini sauce:
- 3 garlic cloves, crushed
- 3 tbsp tahini
- 1 tbsp fresh lemon juice
- 1 tbsp white miso paste
- 1 tsp ground cumin
To serve:
- A generous helping of leafy greens; we recommend collard greens, but whatever works for you is good; just remember that dark green is best. Consider cavolo nero, or even kale if that’s your thing, but to be honest this writer doesn’t love kale
- 1 tsp coarsely ground nigella seeds
- Balsamic vinegar, ideally aged balsamic vinegar (this is thicker and sweeter, but unlike most balsamic vinegar reductions, doesn’t have added sugar).
Method
(we suggest you read everything at least once before doing anything)
1) Rinse the bulgur wheat and then soak it in warm water. There is no need to boil it; the warm water is enough to soften it and you don’t need to cook it (bulgur wheat has already been parboiled before it got to you).
2) While you wait, take a small bowl and mix the rest of the ingredients from the tabbouleh section (so, the lemon juice, miso paste, and all those ground spices and MSG/salt and ground nutritional yeast); you’re making a dressing out of all the ingredients here.
3) When the bulgur wheat is soft (expect it to take under 15 minutes), drain it and put it in a big bowl. Add the tomatoes, cucumber, chickpeas, parsley, mint, and spring onions. This now technically qualifies as tabbouleh already, but we’re not done.
4) Add the dressing to the tabbouleh and mix thoroughly but gently (you don’t want to squash the tomatoes, cucumber, etc). Leave it be for at least 15 minutes while the flavors blend.
5) Take the “For the tahini sauce” ingredients (all of them) and blend them with 4 oz water, until smooth. You’re going to want to drizzle this sauce, so if the consistency is too thick for drizzling, add a little more water and/or lemon juice (per your preference), 1 tbsp at a time.
6) Roughly chop the leafy greens and put them in a bowl big enough for the tabbouleh to join them there. The greens will serve as a bed for the tabbouleh itself.
7) Drizzle the tahini over the tabbouleh, and drizzle a little of the aged balsamic vinegar too.
Enjoy!

Hardwiring Happiness – by Dr. Rick Hanson

Publishers are very excitable about “the new science of…”, and it’s almost never actually a new science of. But what about in this case?
No, it isn’t. It’s the very well established science of! And that’s a good thing, because it means this book is able to draw on quite a lot of research and established understanding of how neuroplasticity works, to leverage that and provide useful guidance.
A particular strength of this book is that while it polarizes the idea that some people have “happy amygdalae” and some people have “sad amygdalae”, it acknowledges that it’s not just a fated disposition and is rather the result of the lives people have led… And then provides advice on upgrading from sad to happy, based on the assumption that the reader is quite possibly coming from a non-ideal starting point.
The bookdoes an excellent job of straddling neuroscience and psychology, which sounds like not much of a straddle (the two are surely very connected, after all, right?) but this does mean that we’re hearing about the chemical structure of DNA inside the nuclei of the neurons of the insula, not long after reading an extended gardening metaphor about growth, choices, and vulnerabilities.
Bottom line: if you’d like a guide to changing your brain for the better (happier) that’s not just “ask yourself: what if it goes well?” and similar CBTisms, then this is a fine book for you.

Overcoming Tendonitis – by Dr. Steven Low & Dr. Frank Skretch
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.
If you assumed tendonitis to be an inflammatory condition, you’re not alone. However, it’s not; the “-itis” nomenclature is a misnomer, and while one can rarely go wrong with reducing chronic/systemic inflammation, it’s not the cure for tendonitis.
What, then, is tendonitis and what does cure it? It’s a non-inflammatory proliferation disorder, meaning, something is growing (or in this case, simply being replaced) in a way it shouldn’t. As to fixing it, that’s more complex.
This book does cover 20 interventions (sorted into “major” and “minor”), ranging from exercise therapies to surgery, with many things between. It also examines popular myths that do not help, such as rest, ice, heat, and analgesics.
The style of this book is hard science, but don’t worry, it explains everything along the way. It does however mean that if you’re not very accustomed to wading through scientific material, you can’t just dip into the middle of the book and be guaranteed to understand what’s going on. Indeed, before even getting to discussing tendonitis/tendinopathy, the first chapter is very reassuringly dedicated to “understanding the levels and classification of evidence in studies”, along with the assorted scales and guidelines of the Center for Evidence-Based Medicine.
The rest, however, is about the etiology, diagnosis, and treatment of tendonitis and tendinopathy more generally. One interesting thing is that, according to the abundant high-quality evidence presented in this book, what works for one body part’s tendonitis does not necessarily work for another body part, so we get quite a part-by-part rundown.
Bottom line: this book has a wealth of useful, applicable information about management of tendonitis, making it indispensable if you or a loved one suffer from such—but settle in, because it’s not a light read.

Women’s Strength Training Anatomy – by Frédéric Delavier
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.
Fitness guides for women tend to differ from fitness guides for men, in the wrong ways:
“Do some squats and jumping jacks, and here’s a exercise for your abs; you too can look like our model here”
In those other books we are left wonder: where’s the underlying information? Where are the explanations that aren’t condescending? Where, dare we ask, is the understanding that a woman might ever lift something heavier than a baby?
Delavier, in contrast, delivers. With 130 pages of detailed anatomical diagrams for all kinds of exercises to genuinely craft your body the way you want it for you. Bigger here, smaller there, functional strength, you decide.
And rest assured: no, you won’t end up looking like Arnold Schwarzenegger unless you not only eat like him, but also have his genes (and possibly his, uh, “supplement” regime).
What you will get though, is a deep understanding of how to tailor your exercise routine to actually deliver the personalized and specific results that you want.

Too Much Or Too Little Testosterone?
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.
One Man’s Saw Palmetto Is Another Woman’s Serenoa Repens…
Today we’re going to look at saw palmetto. So, first:
What is it?
Saw palmetto is a type of palm native to the southeastern United States. Its scientific name is “Serenoa repens”, so if that name appears in studies we cite, it’s the same thing. By whichever name, it’s widely enjoyed as a herbal supplement.
Why do people take it?
Here’s where it gets interesting, because people take it for some completely opposite reasons…
Indeed, searching for it on the Internet will cause Google to suggest “…for men” and “…for women” as the top suggestions.
That’s because it works on testosterone, and testosterone can be a bit of a double-edged sword, so some people want to increase or decrease certain testosterone-related effects on their body.
And it works for both! Here be science:
- Testosterone (henceforth, “T”) is produced in the human body.
- Yes, all human bodies, to some extent.
- An enzyme called 5-alpha-reductase converts T in to DHT (dihydrogen testosterone)
- DHT is a much more potent androgen (masculinizing agent) than T alone, such that its effects are often unwanted, including:
- Enlarged prostate (if you have one)
- Hair loss (especially in men)
- New facial hair growth (usually unwanted by women)
- Women are more likely to get this due to PCOS and/or the menopause
To avoid those effects, you really want less of your T to be converted into DHT.
Saw palmetto is a 5α-reductase inhibitor, so if you take it, you’ll have less DHT, and you’ll consequently lose less hair, have fewer prostate problems, etc.
^The above study showed that saw palmetto extract performed comparably to finasteride. Finasteride is the world’s main go-to prescription drug for treating enlarged prostate and/or hair loss.

Hair today… Growing tomorrow!
So, what was that about increasing T levels?
Men usually suffer declining T levels as they get older, with a marked drop around the age of 45. With lower T comes lower energy, lower mood, lower libido, erectile dysfunction, etc.
Guess what… It’s T that’s needed for those things, not DHT. So if you block the conversion of T to DHT, you’ll have higher blood serum T levels, higher energy, higher mood, higher libido, and all that.
(the above assumes you have testicles, without which, your T levels will certainly not increase)
Saw Palmetto Against Enlarged Prostate?
With higher DHT levels in mid-late life, prostate enlargement (benign prostatic hyperlasia) can become a problem for many men. The size of that problem ranges from urinary inconvenience (common, when the prostate presses against the bladder) to prostate cancer (less common, much more serious). Saw palmetto, like other 5α-reductase inhibitors such as finasteride, may be used to prevent or treat this.
Wondering how safe/reliable it is? We found a very high-quality fifteen-year longitudinal observational study of the use of saw palmetto, and it found:
❝The 15 years’ study results suggest that taking S. repens plant extract continuously at a daily dose of 320 mg is an effective and safe way to prevent the progression of benign prostatic hyperplasia.❞
Want a second opinion? We also found a 10-year study (by different researchers with different people taking it), which reached the same conclusion:
❝The results of study showed the absence of progression, both on subjective criteria (IPSS, and QoL scores), and objective criteria (prostate volume, the rate of urination, residual urine volume). Furthermore, patients had no undesirable effects directly related to the use of this drug.❞
- IPSS = International Prostate Symptom Score
- QoL = Quality of Life
❝But wait a minute; I, a man over the age of 45 with potentially declining T levels but a fabulous beard, remember that you said just a minute ago that saw palmetto is used by women to avoid having facial hair; I don’t want to lose mine!❞
You won’t. Once your facial hair follicles were fully developed and activated during puberty, they’ll carry on doing what they do for life. That’s no longer regulated by hormones once they’re up and running.
The use of saw palmetto can only be used to limit facial hair if caught early—so it’s more useful at the onset of menopause, for those who have (or will have) such, or else upon the arrival of PCOS symptoms or hirsuitism from some other cause.
Take The Test!
Do you have a prostate, and would like to know your IPSS score, and what that means for your prostate health?
(takes 1 minute, no need to pee or go probing for anything)
Bottom Line on Saw Palmetto
- It blocks the conversion of T into DHT
- It will increase blood serum T levels, thus boosting mood, energy, libido, etc in men (who typically have more T, but whose T levels decline with age)
- It will decrease DHT levels, thus limiting hair loss (especially in men) and later-life new facial hair growth (especially in women).
- It can be used to prevent or treat prostate enlargement
- Bonus: it’s a potent antioxidant and thus reduces general inflammation (in everyone)

Getting Things Done – by David Allen
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 “to-do” lists are usually hopelessly tangled:
“To do thing x needs thing y doing first but that can only be done with information that I must get by doing thing z”, and so on.
Suddenly that two-minute task is looking like half an hour, which is making our overall to-do list look gargantuan. Tackling tiny parts of tasks seems useless; tackling large tasks seems overwhelming. What a headache!
Getting Things Done (“GTD”, to its friends) shows us how to gather all our to-dos, and then use the quickest ways to break down a task (in reality, often a mini-project) into its constituent parts and which things can be done next, and what order to do them in (or defer, or delegate, or ditch).
In a nutshell: The GTD system aims to make all your tasks comprehensible and manageable, for stress-free productivity. No need to strategize everything every time; you have a system now, and always know where to begin.
And by popular accounts, it delivers—many put this book in the “life-changing” category.
