What Is “75 Hard”?

This is Andy Frisella. He’s not a doctor, scientist, nutritionist, personal trainer, or professional athlete, but he has kicked off a viral fitness challenge, so let’s take a look at it:
What it is
Firstly, Frisella asserts that it’s not a fitness challenge, but rather, he describes it as a “transformative mental toughness program”.
Here’s what it consists of:
- Follow a healthy diet plan with no deviations from it (i.e. no “cheat days”)
- Abstain from alcohol
- Exercise 2x per day, 45 minutes each
- One of the exercise sessions each day must be outside
- No rest days
- Drink 3.5 liters of water per day
And the duration? 75 days, hence the name of the fitness challenge transformative mental toughness program.
Why it is
Frisella’s rationale is:
- we must cultivate mental toughness by doing hard things
- allowing ourselves any deviation would be a sign of mental weakness
- if we allow ourselves to deviate, it becomes a habit
For this reason, he does not “allow” any substitutions, for example if somebody wants to do such-and-such a thing slightly differently instead. We put “allow” in quotation marks because of course, he’s not the boss of you, but per the rules of his challenge, at least.
These reasonings are in and of themselves somewhat sound, however, we at 10almonds would argue:
- before doing hard things, it is good to first consider “is it a good idea?” (amputating your leg using only a spork is a “hard thing”, and demonstrates incredible mental toughness, but that doesn’t make it a good idea)
- while being able to decide to do a thing and then do it is great characteristic to have, it’s good to first consider science; for example, restrictive diets with no flexibility simply do not work, and our bodies do require adequate rest, especially if being pushed through hard things, or problems will happen (injuries, illnesses, etc).
- while it’s true that allowing ourselves to deviate can become a habit, it’s good to first consider what habits we want to make, and make those habits, instead of potentially unsustainable or even simply unpleasant ones.

Yoga For Stiff Birds – by Marion Deuchars
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.
Quick show of hands, who here practices yoga in some fashion, but does not necessarily always look Instagrammable while doing it? Yep, same here.
This book is a surprisingly practical introduction to yoga for newcomers, and inspirational motivator for those of us who feel like we should do more.
Rather than studio photography of young models in skimpy attire, popular artist (and well-practised yogi) Marion Deuchars offers in a few brushstrokes what we need to know for each asana, and how to approach it if we’re not so supple yet as we’d like to be.
Bottom line: whether for yourself or as a gift for a loved one (or both!) this is a very charming introduction to (or refresher of) yoga.

One in twenty people has no sense of smell – here’s how they might get it back
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.
During the pandemic, a lost sense of smell was quickly identified as one of the key symptoms of COVID. Nearly four years later, one in five people in the UK is living with a decreased or distorted sense of smell, and one in twenty have anosmia – the total loss of the ability to perceive any odours at all. Smell training is one of the few treatment options for recovering a lost sense of smell – but can we make it more effective?
Smell training is a therapy that is recommended by experts for recovering a lost sense of smell. It is a simple process that involves sniffing a set of different odours – usually essential oils, or herbs and spices – every day.
The olfactory system has a unique ability to regenerate sensory neurons (nerve cells). So, just like physiotherapy where exercise helps to restore movement and function following an injury, repeated exposure to odours helps to recover the sense of smell following an infection, or other cause of smell loss (for example, traumatic head injury).
Several studies have demonstrated the effectiveness of smell training under laboratory conditions. But recent findings have suggested that the real-world results might be disappointing.
One reason for this is that smell training is a long-term therapy. It can take months before patients detect anything, and some people may not get any benefit at all.
In one study, researchers found that after three months of smell training, participation dropped to 88%, and further declined to 56% after six months. The reason given was that these people did not feel as though they noticed any improvement in their ability to smell.
Cross-modal associations
To remedy this, researchers are now investigating how smell training can be improved. One interesting idea is that information from our other senses, or “cross-modal associations”, can be applied to smell training to promote odour perception and improve the results.
Cross-modal associations are described as the tendency for sensory cues from different sensory systems to be matched. For example, brightness tends to be associated with loudness. Pitch is related to size. Colours are linked to temperature, and softness is matched with round shapes, while spiky shapes feel more rough. In previous studies, these associations have been shown to have a considerable influence on how sensory information is processed. Especially when it comes to olfaction.
Recent research has shown that the sense of smell is influenced by a combination of different sensory inputs – not just odours. Sensory cues such as colour, shape, and pitch are believed to play a role in the ability to correctly identify and name odours, and can influence perceptions of odour pleasantness and intensity.
In one study, participants were asked to complete a test that measured their ability to discriminate between different odours while they were presented with the colour red or yellow, an outline drawing of a strawberry or a lemon, or a combination of these colours and shapes. The results suggested that corresponding odour and colour associations (for example, the colour red and strawberry) were linked to increased olfactory performance compared with odours and colours that were not associated (for example, the colour yellow and strawberry).
People who associated strawberries with the colour red performed better on smell tests. GCapture/Shutterstock While projects focusing on harnessing these cross-modal associations to improve treatments for smell loss are underway, research has already started to deliver some promising results.
In a recent study that aimed to investigate whether the effects of smell training could be improved with the addition of cross-modal associations, participants watched a guidance video containing sounds that matched the odours that they were training with. The results suggest that cross-modal interactions plus smell training improved olfactory function compared to smell training alone.
The results reported in recent studies have been promising and offer new insights into the field of olfactory science. It is hoped that this will soon lead to the development of more effective treatment options for smell recovery.
In the meantime, smell training is one of the best things you can do for a lost sense of smell, so patients are encouraged to stick with it so that they give themselves the best chance at recovery.

Who Screens The Sunscreens?
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 Screen The Sunscreens!
Yesterday, we asked you what your sunscreen policy was, and got a spread of answers. Apparently this one was quite polarizing!
One subscriber who voted for “Sunscreen is essential to protect us against skin aging and cancer” wrote:
❝My mom died of complications from melanoma, so we are vigilant about sun and sunscreen. We are a family of campers and hikers and gardeners—outdoors in all seasons—and we never burn❞
Our condolences with regard to your mom! Life is so precious, and when something like that happens, it tends to stick with us. We’re glad you and your family are taking care of yourselves.
Of the subscribers who voted for “I put some on if I think I might otherwise get sunburned”, about half wrote to express uncertainties:
- uncertainty about how safe it is, and
- uncertainty about how helpful it is
…so we’re going to tackle those questions in a moment. But what of those who voted for “Sunscreen is full of harmful chemicals that can cause cancer”?
Of those, only one wrote a message, which was to say one has to be very careful of what is in the formula.
Let’s take a look, then…
Sunscreen is full of harmful chemicals that can cause cancer: True or False?
False—according to current best science. Research is ongoing!
There are four main chemicals (found in most sunscreens) that people tend to worry about:
- Abobenzone
- Oxybenzone
- Octocrylene
- Ecamsule
Now, these two sound like four brands of rocket fuel, but then, dihydrogen monoxide (DHMO), which is also found in most sunscreens, sounds like a deadly toxin too. That’s water, by the way.
But what of these four chemicals? Well, as we say, research is ongoing, but we found a study that measured all four, to see how much got into the blood, and what adverse effects, if any, this caused.
We’ll skip to their conclusion:
❝In this preliminary study involving healthy volunteers, application of 4 commercially available sunscreens under maximal use conditions resulted in plasma concentrations that exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens. The systemic absorption of sunscreen ingredients supports the need for further studies to determine the clinical significance of these findings. These results do not indicate that individuals should refrain from the use of sunscreen.❞
Now, “exceeded the threshold established by the FDA for potentially waiving some nonclinical toxicology studies for sunscreens” sounds alarming, so why did they close with the words “These results do not indicate that individuals should refrain from the use of sunscreen”?
Let’s skip back up to a line from the results:
❝The most common adverse event was rash, which developed in 1 participant with each sunscreen.❞
This was most probably due to the oxybenzone, which can cause allergic skin reactions in some people.
Let us take a moment to remember the most common adverse event that occurs from not wearing sunscreen: sunburn!
You can read the full study here:
None of those ingredients have been found to be carcinogenic, even at the maximal blood plasma concentrations studied, from applications 4x/day to 75% of the body.
UVA rays, on the other hand, are absolutely very much known to cause cancer, and the effect is cumulative.
Sunscreen is essential to protect us against skin aging and cancer: True or False?
True, unequivocally, unless we live indoors and/or otherwise never go about under sunlight.
“But our ancestors—” lived under the same sun we do, and either used sunscreen or got advanced skin aging and cancer.
Sunscreen of times past ranged from mud to mineral lotions, but it’s pretty much always existed. Even non-human animals that have skin and don’t have fur or feathers, tend to take mud-baths in sunny parts of the world.
If you’d like to avoid oxybenzone and other chemicals, though, you might have your reasons. Maybe you’re allergic, or maybe you read that it’s a potential endocrine disruptor with estrogen-like and anti-androgenic properties that you don’t want.
There are other options, to include physical blockers containing zinc and titanium dioxide, which are generally recognized as safe and effective ingredients.
If you’re interested, you can even make your own sunscreen that blocks both UVA and UVB rays (UVA is what causes skin cancer; UVB is “milder” and is what causes sunburn):

The Wandering Mind – by Dr. Michael Corballis
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 mind’s tendency to wander can be a disability, but could it also be a superpower? Dr. Corballis makes the case for such.
While many authors focus on, well, how to focus, Dr. Corballis argues in this book that our wandering imagination can be more effective at problem-solving and creative tasks, than a focused, blinkered mind.
The book’s a quick read (184 pages of quite light reading), and yet still quite dense with content. He takes us on a tour of the brain, theory of mind, the Default Mode Network (where a lot of the brain’s general ongoing organization occurs), learning, memory, forgetting, and creativity.
Furthermore, he cites (and explains) studies showing what kinds of “breaks” from mental work allow the wandering mind to do its thing at peak efficiency, and what kinds of breaks are counterproductive. Certainly this has practical applications for all of us!
Bottom line: if you’d like to be less frustrated by your mind’s tendency to wander, this is a fine book to show how to leverage that trait to your benefit.

Egg Whites vs Whole Eggs – 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 egg whites to whole eggs, we picked the whole eggs.
Why?
Egg whites are mostly protein. Egg yolks are mostly fat, with some protein.
However, fat ≠ bad, and the yolk is also where the choline is stored, which itself (as well as its benefits for your brain) will tend to reduce fat storage in the body.
Furthermore, the yolk contains an assortment of vitamins, minerals, and essential amino acids. After all, the yolk is there specifically to contain everything needed to turn a cluster of cells into a small bird.

Do Essential Oils Really Have Medicinal Properties?
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 😎
❝Do essential oils really have scientific merit?❞
Great question! Assuming you mean “…for medicinal purposes” then it really depends on the oil in question.
For example, one can probably buy a big book of essential oils from a New Age store, and a lot of claims for different oils will not have any scientific backing whatsoever.
However! Some definitely do. For example, we wrote a little while back about ginger:
Ginger Does A Lot More Than You Think
Now, the active compound that gives ginger those properties and more is gingerol. Which is usually found as pure ginger oil, in other words, ginger essential oil.
Another essential oil that definitely does have benefits is that of Boswellia serrata, commonly known as frankincense. It can be used in various forms, and the essential oil is one of them; see:
- Five Supplements That Actually Work Vs Arthritis
- When Painkillers Aren’t Helping, These Things Might: Science-Based Alternative Pain Relief
Meanwhile, menthol, the essential oil of peppermint, has its pros and cons:

And lavender essential oil does really have a sedative effect:
Herbs for Evidence-Based Health & Healing
If you have a different, particular essential oil in mind, let us know, and we can do a deep-dive on it for one of our “Research Review” editions!
A note on safety
Essential oils are pure and undiluted extracts of what’s usually a particularly potent chemical from a plant. Two things to bear in mind about this:
- Just because a chemical is potent, does not mean it will necessarily help you in a specific way, or indeed at all. On the contrary, many potent chemicals are simply harmful. So, be careful.
- Essential oils being so strong means that usually only a drop or two is required for effects; consult available literature (or ask us to do that for you!), and employ good safety practices such as:
- Do not use undiluted essential oils on your skin or internally
- If you are going to use it internally (diluted, following instructions from a reputable source, and with your doctor’s blessing, please) then test it on your skin first at the same dilution, in case of any adverse reaction.
- However you are using it, if you have any kind of adverse reaction, stop, and seek medical attention if it’s severe and/or it persists.
Take care!
