We urge you to overlook the cliché cover art (we don’t know what they were thinking, going for the headless suited torso) because…
This one could be the best investment you make in your career this year! You may be wondering what the titular 7 principles are. We won’t keep you guessing; they are:
- Professional development: personal excellence, productivity, and time management
- Leadership development: mindset and essential leadership skills
- Personal development: your motivation, character, and confidence as a leader
- Career management: plan your career, get promoted and paid well
- Social skills & networking: work and connect with the right people
- Business- & company-understanding: the big picture
- Commitment: make the decision and commit to becoming a great leader
A lot of leadership books repeat the same old fluff that we’ve all read many times before… padded with a lot of lengthy personal anecdotes and generally editorializing fluff. Not so here!
While yes, this book does also cover some foundational things first, it’d be remiss not to. It also covers a whole (much deeper) range of related skills, with down-to-earth, brass tacks advice on putting them into practice.
This is the kind of book you will want to set as a recurring reminder in your phone, to re-read once a year, or whatever schedule seems sensible to you.
There aren’t many books we’d put in that category!

The Best Form Of Sugar During Exercise
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!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝What is the best form of sugar for an energy kick during exercise? Both type of sugar eg glicoae fructose dextrose etc and medium, ie drink, gel, solids etc❞
Great question! Let’s be clear first that we’re going to answer this specifically for the context of during exercise.
Because, if you’re not actively exercising strenuously right at the time when you’re taking the various things we’re going to be talking about, the results will not be the same.
For scenarios that are anything less than “I am exercising right now and my muscles (not joints, or anything else) are feeling the burn”, then instead please see this:
Snacks & Hacks: Eating For Energy (In Ways That Actually Work)
Because, to answer your question, we’re going to be going 100% against the first piece of advice in that article, which was “Skip the quasi-injectables”, i.e., anything marketed as very quick release. Those things are useful for diabetics to have handy just in case of needing to urgently correct a hypo, but for most people most of the time, they’re not. See also:
Which Sugars Are Healthier, And Which Are Just The Same?
However…
When strenuously exercising in a way that is taxing our muscles, we do not have to worry about the usual problem of messing up our glucose metabolism by overloading our body with sugars faster than it can use it (thus: it has to hurriedly convert glucose and shove it anywhere it’ll fit to put it away, which is very bad for us), because right now, in the exercise scenario we’re describing, the body is already running its fastest metabolism and is grabbing glucose anywhere it can find it.
Which brings us to our first key: the best type of sugar for this purpose is glucose. Because:
- glucose: the body can use immediately and easily convert whatever’s spare to glycogen (a polysaccharide of glucose) for storage
- fructose: the body cannot use immediately and any conversion of fructose to glycogen has to happen in the liver, so if you take too much fructose (without anything to slow it down, such as the fiber in whole fruit), you’re not only not going to get usable energy (the sugar is just going to be there in your bloodstream, circulating, not getting used, because it doesn’t trigger insulin release and insulin is the gatekeeper that allows sugar to be used), but also, it’s going to tax the liver, which if done to excess, is how we get non-alcoholic fatty liver disease.
- sucrose: is just a disaccharide of glucose and fructose, so it first gets broken down into those, and then its constituent parts get processed as above. Other disaccharides you’ll see mentioned sometimes are maltose and lactose, but again, they’re just an extra step removed from useful metabolism, so to save space, we’ll leave it at that for those today.
- dextrose: is just glucose, but when the labeller is feeling fancy. It’s technically informational because it specifies what isomer of glucose it is, but basically all glucose found in food is d-glucose, i.e. dextrose. Other isomers of glucose can be synthesized (very expensively) in laboratories or potentially found in obscure places (the universe is vast and weird), but in short: unless someone’s going to extreme lengths to get something else, all glucose we encounter is dextrose, and all (absolutely all) dextrose is glucose.
We’d like to show scientific papers contesting these head-to-head for empirical proof, but since the above is basic chemistry and physiology, all we could find is papers taking this for granted and stating in their initial premise that sports drinks, gels, bars usually contain glucose as their main sugar, potentially with some fructose and sucrose. Like this one:
A Comprehensive Study on Sports and Energy Drinks
As for how to take it, again this is the complete opposite of our usual health advice of “don’t drink your calories”, because in this case, for once…
(and again, we must emphasize: only while actively doing strenuous exercise that is making specifically your muscles burn, not your joints or anything else; if your joints are burning you need to rest and definitely don’t spike your blood sugars because that will worsen inflammation)
…just this once, we do want those sugars to be zipping straight into the blood. Which means: liquid is best for this purpose.
And when we say liquid: gel is the same as a drink, so far as the body is concerned, provided the body in question is adequately hydrated (i.e., you are also drinking water).
Here are a pair of studies (by the same team, with the same general methodology), testing things head-to-head, with endurance cyclists on 6-hour stationary cycle rides:
CHO Oxidation from a CHO Gel Compared with a Drink during Exercise
Meanwhile, liquid beat solid, but only significantly so from the 90-minute mark onwards, and even that significant difference was modest (i.e. it’s clinically significant, it’s a statistically reliable result and improbable as random happenstance, but the actual size of the difference was not huge):
Oxidation of Solid versus Liquid CHO Sources during Exercise
We would hypothesize that the reason that liquids only barely outperformed solids for this task is precisely because the solids in question were also designed for the task. When a company makes a fast-release energy bar, they don’t load it with fiber to slow it down. Which differentiates this greatly from, say, getting one’s sugars from whole fruit.
If the study had compared apples to apple juice, we hypothesize the results would have been very different. But alas, if that study has been done, we couldn’t find it.
Today has been all about what’s best during exercise, so let’s quickly finish with a note on what’s best before and after:

Could my glasses be making my eyesight worse?
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.
So, you got your eyesight tested and found out you need your first pair of glasses. Or you found out you need a stronger pair than the ones you have. You put them on and everything looks crystal clear. But after a few weeks things look blurrier without them than they did before your eye test. What’s going on?
Some people start to wear spectacles for the first time and perceive their vision is “bad” when they take their glasses off. They incorrectly interpret this as the glasses making their vision worse. Fear of this might make them less likely to wear their glasses.
But what they are noticing is how much better the world appears through the glasses. They become less tolerant of a blurry world when they remove them.
Here are some other things you might notice about eyesight and wearing glasses.
Lazy eyes?
Some people sense an increasing reliance on glasses and wonder if their eyes have become “lazy”.
Our eyes work in much the same way as an auto-focus camera. A flexible lens inside each eye is controlled by muscles that let us focus on objects in the distance (such as a footy scoreboard) by relaxing the muscle to flatten the lens. When the muscle contracts it makes the lens steeper and more powerful to see things that are much closer to us (such as a text message).
From the age of about 40, the lens in our eye progressively hardens and loses its ability to change shape. Gradually, we lose our capacity to focus on near objects. This is called “presbyopia” and at the moment there are no treatments for this lens hardening.
Optometrists correct this with prescription glasses that take the load of your natural lens. The lenses allow you to see those up-close images clearly by providing extra refractive power.
Once we are used to seeing clearly, our tolerance for blurry vision will be lower and we will reach for the glasses to see well again.
The wrong glasses?
Wearing old glasses, the wrong prescription (or even someone else’s glasses) won’t allow you to see as well as possible for day-to-day tasks. It could also cause eyestrain and headaches.
Incorrectly prescribed or dispensed prescription glasses can lead to vision impairment in children as their visual system is still in development.
But it is more common for kids to develop long-term vision problems as a result of not wearing glasses when they need them.
By the time children are about 10–12 years of age, wearing incorrect spectacles is less likely to cause their eyes to become lazy or damage vision in the long term, but it is likely to result in blurry or uncomfortable vision during daily wear.
Registered optometrists in Australia are trained to assess refractive error (whether the eye focuses light into the retina) as well as the different aspects of ocular function (including how the eyes work together, change focus, move around to see objects). All of these help us see clearly and comfortably.
Younger children with progressive vision impairments may need more frequent eye tests. Shutterstock What about dirty glasses?
Dirty or scratched glasses can give you the impression your vision is worse than it actually is. Just like a window, the dirtier your glasses are, the more difficult it is to see clearly through them. Cleaning glasses regularly with a microfibre lens cloth will help.
While dirty glasses are not commonly associated with eye infections, some research suggests dirty glasses can harbour bacteria with the remote but theoretical potential to cause eye infection.
To ensure best possible vision, people who wear prescription glasses every day should clean their lenses at least every morning and twice a day where required. Cleaning frames with alcohol wipes can reduce bacterial contamination by 96% – but care should be taken as alcohol can damage some frames, depending on what they are made of.
When should I get my eyes checked?
Regular eye exams, starting just before school age, are important for ocular health. Most prescriptions for corrective glasses expire within two years and contact lens prescriptions often expire after a year. So you’ll need an eye check for a new pair every year or so.
Kids with ocular conditions such as progressive myopia (short-sightedness), strabismus (poor eye alignment), or amblyopia (reduced vision in one eye) will need checks at least every year, but likely more often. Likewise, people over 65 or who have known eye conditions, such as glaucoma, will be recommended more frequent checks.
Eye checks can detect broader health issues. Shutterstock An online prescription estimator is no substitute for a full eye examination. If you have a valid prescription then you can order glasses online, but you miss out on the ability to check the fit of the frame or to have them adjusted properly. This is particularly important for multifocal lenses where even a millimetre or two of misalignment can cause uncomfortable or blurry vision.
Conditions such as diabetes or high blood pressure, can affect the eyes so regular eye checks can also help flag broader health issues. The vast majority of eye conditions can be treated if caught early, highlighting the importance of regular preventative care.

Before You Reach For That Tylenol…
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.
First, on names: we’ve titled this with “Tylenol” because that’s a well-known brand name, but the drug name is paracetamol or acetaminophen:
- paracetamol is the drug name used by the World Health Organization, and thus also most countries.
- acetaminophen is the drug name used in Canada, Colombia, Iran, Japan, US, and Venezuela.
They are absolutely the same drug.
Firstly, obviously, do avoid overdose
The safe dosage described on the packet is generally accurate (usually around 4g/day, spaced out at 1g per 4 hours), and the dose required for toxicity is generally about 10g, or 200mg/kg body weight, whichever is lower. Since a single dose usually contains 2x 500mg = 1g, that makes overdose all too easy.
The amount required for toxicity can be misleading too, because that’s assuming…
- a healthy liver
- no other health problems
- no other medications that interact or add to the toxicity
- no medications that strain the liver (as with many pro-drugs, and drugs in general that are metabolized by the liver, which is lots).
Which is a lot of assumptions! Especially given that the liver can only process so much at once, meaning that if your liver has a lot of things to do, it can get a backlog, and you think “I’m not taking anything with this painkiller that I shouldn’t” but your liver is still metabolizing the last of last night’s glass of wine and one of your regular medications from this morning, because previously it was still metabolizing things from the day before yesterday, and so on.
See also: How To Regenerate Your Liver ← the liver is an incredible organ that does an amazing job, but it can’t do that if you don’t do this
Please don’t overdose deliberately either. Intentional overdoses make up a very large portion of acetaminophen overdoses (exact figures vary from year to year and place to place, but it’s always high), and what a lot of people doing that don’t realize is:
- it’s a very unpleasant way to die. You’ll take it, you might get some initial symptoms within the first hours or you might not, then you’ll probably feel better, and then the next day or so, you’ll enter the organs-shutting-down stage that usually will take most of a week to kill you slowly and painfully. Often your kidneys will go first but it’ll usually be liver necrosis that deals the final blow.
- it’s very difficult to treat. Stomach-pumping might work if you get it within 1 hour of overdose, and activated charcoal might help if you get it within 2 hours. Acetylcysteine may reduce the toxicity if you get it within the 8–48 hour window (depending on the speed of gastric emptying), but whether or not that will help depends on the severity of the overdose and other factors, so this is not something to bet on. After 48 hours, a liver transplant is the last resort, without which, mortality is around 95%.
Unfortunately, this means that a lot of people who do not intend to die horribly, and hoped to either die peacefully or else be saved, die horribly instead.
Ok, that was not a cheerful topic but it is important, before moving on, we’ll just put this here for anyone it may benefit:
How To Stay Alive (When You Really Don’t Want To) ← this is about suicidality, in yourself or others
Secondly, that dosage is for occasional use only
The problem often starts like this:
❝Due to its perceived safety, paracetamol has long been recommended as the first line drug treatment for osteoarthritis by many treatment guidelines, especially in older people who are at higher risk of drug-related complications❞
People with chronic pain, whether high or low on the pain level of that chronic pain, can very easily get into a habit of “I’ll just take this to take the edge off”, for example when getting up in the morning (often a trigger for pain starting) or going to bed at night (one needs to sleep and the pain is a barrier to that).
But… Those events, getting up and going to bed, it means that taking the drug also becomes part of one’s morning/evening routine—with many people even metering the doses out into pill organizers for the week, with this in mind.
A large (n=582,961) study looked at two groups of people, all aged 65+:
- 180,483 people who had been prescribed paracetamol repeatedly (≥2 prescriptions within six months)
- 402,478 people of the same age who had never been prescribed paracetamol repeatedly
The findings? Bearing in mind that “≥2 prescriptions within six months” is not something generally considered excessive…
❝Acetaminophen use was associated with an increased risk of peptic ulcer bleeding (aHR 1.24; 95% CI 1.16, 1.34), uncomplicated peptic-ulcers (aHR 1.20; 95% CI 1.10, 1.31), lower gastrointestinal-bleeding (aHR 1.36; 95% CI 1.29, 1.46), heart-failure (aHR 1.09; 95% CI 1.06, 1.13), hypertension (aHR 1.07; 95% CI 1.04, 1.11), and chronic kidney disease (aHR 1.19; 95% CI 1.13, 1.24).❞
The researchers concluded:
❝Despite its perceived safety, acetaminophen is associated with several serious complications. Given its minimal analgesic effectiveness, the use of acetaminophen as the first-line oral analgesic for long-term conditions in older people requires careful reconsideration.❞
You can see the study itself here: Incidence of side effects associated with acetaminophen in people aged 65 years or more: a prospective cohort study using data from the Clinical Practice Research Datalink
What to use instead?
It’s been established that taking aspirin regularly isn’t great either:
See: Low-Dose Aspirin & Anemia and Aspirin, CVD Risk, & Potential Counter-Risks
And as for ibuprofen, we don’t have an article about that yet, but it’s gut-unhealthy (harms your microbiome), and besides, anything it can do, ginger can do as well or better (in head-to-head trials; we’re not speaking hyperbolically here):
Ginger Does A Lot More Than You Think ← in fact, it was even found as effective as the combination of acetaminophen, ibuprofen, and caffeine
There are other options though, and as pain is complicated and there’s no one-size-fits-all solution, we’ve compiled the following:
- Dial Down Your Pain
- Stop Pain Spreading
- Managing Chronic Pain (Realistically!)
- The 7 Approaches To Pain Management

The Foot Book – by Dr. Todd Brennan & Dr. Leslie Johnston
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 really is what the subtitle claims it to be: “everything you need to know to take care of your feet”.
Arthritis, bunions, corns, diabetes, eczema, fungus, gout, heel pain, ingrown toenails, joint issues, and that’s just one item for each of the first 10 letters of the alphabet.
There’s a lot in here; the point is that it covers everything from the “serious” to the “cosmetic”, so whether you want to be a foot model for an expensive perfume company or just want to walk without pain, the answer is probably in here.
The goal of this book is to be comprehensive like that, and also with an open agenda to educate the world as to what it actually is that podiatrists do (hint: their years of medical school and further training in residency are not just so that they can trim toenails nicely).
The style is very light and readable, as one might expect from a pair of doctors with many years of experience of explaining exactly these things to patients every day.
Bottom line: if you have feet and would like them to be/remain in good condition, this book is an invaluable resource!

Tips for Avoiding PFAs
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!
Have a question or a request? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Hi, do you have anything helpful on avoiding PFAs?❞
PFAS, or perfluoroalkyl and polyfluoroalkyl substances, are “forever chemicals” made specifically to avoid degradation of industrial and chemical products. Which is great for providing stain and water resistance, but not so great for our bodies or the environment.
To go into all the harms they cause would take a main feature (maybe we will, one of these days), but suffice it to say, they’re not good, and range from cancer and insulin resistance to hypertension and reduced immune response.
To answer your question in a nutshell, avoiding them completely would be almost impossible, but we can reduce our exposure a lot by avoiding single-use food/drink products that have been waterproofed, e.g. paper/bamboo straws, utensils, cups, dishes, take-out containers, etc.
Also, anything advertised as “stain-resistant” that you suspect should be quite stainable by nature, is probably good to avoid too.
For more detailed information than we have room for here today, here’s a helpful overview:

Brown Rice vs Russet Potatoes – 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 brown rice to russet potatoes, we picked the rice.
Why?
First we’ll note: for brevity and to avoid undue repetitiveness, we’re henceforth going to just say “rice” and “potato”, respectively, but values and conclusions are still for brown rice and russet potatoes. Also, we are including the flesh and skin into the metrics for the potato (without the skin, many nutrients are no longer present).
In terms of macros, the rice has more fiber, carbs, and protein. It’s difficult to compare glycemic indices in this case, because they both need cooking before eating, and how one cooks them (and whether one cools them) along with other preparatory methods will change the GI considerably. Thus, we’ll simply go with the more nutritionally dense option, and that’s the rice.
In the category of vitamins, the rice has much more of vitamins B1, B2, B3, B5, B6, B7, B9, E, and choline, while the potato has more of vitamins C and K. A clear win for rice (and by the way, that’s 60x the vitamin E, but as potatoes don’t have much vitamin E, in practical terms, it’s actually the B-vitamins where rice’s strengths really show, as potatoes aren’t a bad source but rice is amazing).
When it comes to minerals, rice has a lot more copper, iron, magnesium, manganese, phosphorus, selenium, and zinc, while potato has more calcium and potassium. Another easy win for rice.
You may be wondering about phytic acid: brown rice contains this by default, and it is something of an antinutrient (i.e., if left as-is, it reduces the bioavailability of other nutrients), and/but the phytic acid content is reduced to negligible by two things: soaking and heating (especially if those two things are combined) ← doing this the way described results in bioavailability of nutrients that’s even better than if there were just no phytic acid, albeit it requires you having the time to soak, and do so at temperature.
All in all, adding up the sections makes for an overall win for brown rice, but by all means enjoy either or both; diversity is good!
