Dr. Michelle Jorgensen, a dentist, tells us that it’s a lot rarer than people think to actually need a crown or a root canal; there are ways of avoiding such:
The tooth, the whole tooth, and nothing but the tooth?
First, some of the problems with the treatments that are most popular, especially in the US:
Problems with root canals:
- Involves cleaning and filling the tooth’s main canal but leaves microtubules that can harbor dead tissue and attract bacteria.
- This can lead to infections, often undetected for a long time due to the nerve removal, potentially harming overall health and weakening the tooth.
- Root canals often result in brittle teeth that can break, necessitating crowns.
And then…
Problems with crowns:
- A crown requires significant removal of tooth structure (up to 1.5 mm of enamel), making the tooth more vulnerable and sensitive.
- Crowns can also lead to new cavities underneath due to weak bonding to dentin.
- The cycle often leads from a healthy tooth to fillings, crowns, root canals, and eventual extraction (and then, perhaps, an implant in its place). That’s great for the dentist, but not so great for you.
Biomimetic dentistry the exciting name currently being used for what has been more prosaically called “conservative restorative dentistry”, which in turn has also been known by other names in recent decades, and its goal is to strengthen and preserve natural teeth as much as possible.
Methods it uses:
- Treats affected but still living teeth with non-invasive procedures.
- Uses ozone treatment to kill bacteria in deep cavities, avoiding direct nerve exposure.
- Applies conservative partial restorations like onlays instead of full crowns.
Benefits of this approach:
- Preserves enamel, minimizes trauma, and reduces the risk of tooth death.
- Maintains long-term tooth structure and health.
- 95% success rate in saving affected teeth without resorting to root canals.
In short, Dr. Jorgensen says that 60–80% of traditional crowns and root canals can be avoided. Which is surely a good thing.

The Intelligence Trap – by David Robson
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’re including this one under the umbrella of “general wellness”, because it happens that a lot of very intelligent people make stunningly unfortunate choices sometimes, for reasons that may baffle others.
The author outlines for us the various reasons that this happens, and how. From the famous trope of “specialized intelligence in one area”, to the tendency of people who are better at acquiring knowledge and understanding to also be better at acquiring biases along the way, to the hubris of “I am intelligent and therefore right as a matter of principle” thinking, and many other reasons.
Perhaps the greatest value of the book is the focus on how we can avoid these traps, narrow our bias blind spots, and play to our strengths while paying full attention to our weaknesses.
The style is very readable, despite having a lot of complex ideas discussed along the way. This is entirely to be expected of this author, an award-winning science writer.
Bottom line: if you’d like to better understand the array of traps that disproportionately catch out the most intelligent people (and how to spot such), then this is a great book for you.

The Polyvagal Theory – by Dr. Stephen Porges
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.
Do you ever find that your feelings (or occasionally: lack thereof) sometimes can seem mismatched with the observed facts of your situation? This book unravels that mystery—or rather, that stack of mysteries.
Dr. Porges’ work on this topic is, by the way, the culmination of 40 years of research. While he’s not exactly a household name to the layperson, he’s very respected in his field, and this book is his magnum opus.
Here he explains the disparate roles of the two branches of the vagus nerve (hence: polyvagal theory). At least, the two branches that we mammals have; non-mammalian vertebrates have only one. This makes a big difference, because of the cascade of inhibitions that this allows.
The answer to the very general question “What stops you from…?” is usually found somewhere down this line of cascade of inhibitions.
These range from “what stops you from quitting your job/relationship/etc” to “what stops you from freaking out” to “what stops you from relaxing” to “what stops you from reacting quickly” to “what stop you from giving up” to “what stops you from gnawing your arm off” and many many more.
And because sometimes we wish we could do something that we can’t, or wish we wouldn’t do something that we do, understanding this process can be something of a cheat code to life.
A quick note on style: the book is quite dense and can be quite technical, but should be comprehensible to any layperson who is content to take their time, because everything is explained as we go along.
Bottom line: if you’d like to better understand the mysteries of how you feel vs how you actually are, and what that means for what you can or cannot wilfully do, this is a top-tier book

Kiwi vs Lemon – 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 kiwi to lemon, we picked the kiwi.
Why?
A fairly straightforward one today!
In terms of macros, kiwi has more protein, carbs, and fiber, the ratio of the latter two also giving it the lower glycemic index. An easy win for kiwi here.
In the category of vitamins, kiwi has more of vitamins A, B2, B3, B9, C, E, K, and choline, while lemon has more of vitamins B1 and B6. Yes, that’s right, lemon didn’t even win on the vitamin C that it’s famous for. In any case, a clear 8:2 win for kiwi.
Looking at minerals, kiwi has more calcium, copper, magnesium, manganese, phosphorus, potassium, and zinc, while lemon has more iron and selenium. So, looking at this 7:2 win for kiwi, you might want to reconsider that “glass of lemon water to replenish minerals” trend!
None of this is to knock lemons, by the way; lemons are still a very respectable fruit, nutritionally. Probably very few people are out there eating lemons the way one might eat kiwi…
(writer’s note: I say “very few”, as once upon a time when my son was small, I remember coming into the kitchen to find he had helped himself to lemon wedges and was just eating them, so it can happen. But I also one time when he was just as small, found him drinking hot sauce directly from the bottle, so hey, he clearly already enjoyed strong flavors. Lest I seem a very inattentive mother, I’ll say in my defense that our kitchen has no real toddler-height hazards when the oven is cold, and those items were from the bottom of the fridge, so easy to access if I leave the room for a moment to grab something)
…but what we do want to say here is: if you don’t care for lemons so much, you’re not missing out. If the lemon water isn’t calling to you, you can skip it guilt-free.
In any case, do enjoy either or both, but kiwi’s the clear winner here!

Why do disinfectants only kill 99.9% of germs? Here’s the science
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.
Have you ever wondered why most disinfectants indicate they kill 99.9% or 99.99% of germs, but never promise to wipe out all of them? Perhaps the thought has crossed your mind mid-way through cleaning your kitchen or bathroom.
Surely, in a world where science is able to do all sorts of amazing things, someone would have invented a disinfectant that is 100% effective?
The answer to this conundrum requires understanding a bit of microbiology and a bit of mathematics.
Davor Geber/Shutterstock What is a disinfectant?
A disinfectant is a substance used to kill or inactivate bacteria, viruses and other microbes on inanimate objects.
There are literally millions of microbes on surfaces and objects in our domestic environment. While most microbes are not harmful (and some are even good for us) a small proportion can make us sick.
Although disinfection can include physical interventions such as heat treatment or the use of UV light, typically when we think of disinfectants we are referring to the use of chemicals to kill microbes on surfaces or objects.
Chemical disinfectants often contain active ingredients such as alcohols, chlorine compounds and hydrogen peroxide which can target vital components of different microbes to kill them.
Diseinfectants can contain a range of ingredients. Maridav/Shutterstock The maths of microbial elimination
In the past few years we’ve all become familiar with the concept of exponential growth in the context of the spread of COVID cases.
This is where numbers grow at an ever-accelerating rate, which can lead to an explosion in the size of something very quickly. For example, if a colony of 100 bacteria doubles every hour, in 24 hours’ time the population of bacteria would be more than 1.5 billion.
Conversely, the killing or inactivating of microbes follows a logarithmic decay pattern, which is essentially the opposite of exponential growth. Here, while the number of microbes decreases over time, the rate of death becomes slower as the number of microbes becomes smaller.
For example, if a particular disinfectant kills 90% of bacteria every minute, after one minute, only 10% of the original bacteria will remain. After the next minute, 10% of that remaining 10% (or 1% of the original amount) will remain, and so on.
Because of this logarithmic decay pattern, it’s not possible to ever claim you can kill 100% of any microbial population. You can only ever scientifically say that you are able to reduce the microbial load by a proportion of the initial population. This is why most disinfectants sold for domestic use indicate they kill 99.9% of germs.
Other products such as hand sanitisers and disinfectant wipes, which also often purport to kill 99.9% of germs, follow the same principle.
You might have noticed none of the cleaning products in your laundry cupboard kill 100% of germs. Africa Studio/Shutterstock Real-world implications
As with a lot of science, things get a bit more complicated in the real world than they are in the laboratory. There are a number of other factors to consider when assessing how well a disinfectant is likely to remove microbes from a surface.
One of these factors is the size of the initial microbial population that you’re trying to get rid of. That is, the more contaminated a surface is, the harder the disinfectant needs to work to eliminate the microbes.
If for example you were to start off with only 100 microbes on a surface or object, and you removed 99.9% of these using a disinfectant, you could have a lot of confidence that you have effectively removed all the microbes from that surface or object (called sterilisation).
In contrast, if you have a large initial microbial population of hundreds of millions or billions of microbes contaminating a surface, even reducing the microbial load by 99.9% may still mean there are potentially millions of microbes remaining on the surface.
Time is is a key factor that determines how effectively microbes are killed. So exposing a highly contaminated surface to disinfectant for a longer period is one way to ensure you kill more of the microbial population.
This is why if you look closely at the labels of many common household disinfectants, they will often suggest that to disinfect you should apply the product then wait a specified time before wiping clean. So always consult the label on the product you’re using.
Disinfectants won’t necessarily work in your kitchen exactly like they work in a lab. Ground Picture/Shutterstock Other factors such as temperature, humidity and the type of surface also influence how well a disinfectant works outside the lab.
Similarly, microbes in the real world may be either more or less sensitive to disinfection than those used for testing in the lab.
Disinfectants are one part infection control
The sensible use of disinfectants plays an important role in our daily lives in reducing our exposure to pathogens (microbes that cause illness). They can therefore reduce our chances of getting sick.
The fact disinfectants can’t be shown to be 100% effective from a scientific perspective in no way detracts from their importance in infection control. But their use should always be complemented by other infection control practices, such as hand washing, to reduce the risk of infection.

The Real Benefit Of Genetic Testing
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.
Genetic Testing: Health Benefits & Methods
Genetic testing is an oft-derided American pastime, but there’s a lot more to it than finding out about your ancestry!
Note: because there are relatively few companies offering health-related genetic testing services, and we are talking about the benefits of those services, some of this main feature may seem like an advert.
It’s not; none of those companies are sponsoring us, and if any of them become a sponsor at some point, we’ll make it clear and put it in the clearly-marked sponsor segment.
As ever, our only goal here is to provide science-backed information, to enable you to make your own, well-informed, decisions.
Health genomics & genetic testing
The basic goal of health genomics and genetic testing is to learn:
- What genetic conditions you have
- Clearcut genetic conditions, such as Fragile X syndrome, or Huntington’s disease
- What genetic predispositions you have
- Such as an increased/decreased risk for various kinds of cancer, diabetes, heart conditions, and so forth
- What genetic traits you have
- These may range from “blue eyes” to “superathlete muscle type”
- More specifically, pharmacogenomic information
- For example, “fast caffeine metabolizer” or “clopidogrel (Plavix) non-responder” (i.e., that drug simply will not work for you)
Wait, what’s the difference between health genomics and genetic testing?
- Health genomics is the science of how our genes affect our health.
- Genetic testing can be broadly defined as the means of finding out which genes we have.
A quick snippet…
More specifically, a lot of these services look at which single nucleotide polymorphisms (SNPs, pronounced “snips”) we have. While we share almost all of our DNA with each other (and indeed, with most vertebrates), our polymorphisms are the bits that differ, and are the bits that, genetically speaking, make us different.
So, by looking just at the SNPs, it means we “only” need to look at about 3,000,000 DNA positions, and not our entire genome. For perspective, those 3,000,000 DNA positions make up about 0.1% of our whole genome, so without focusing on SNPs, the task would be 1000x harder.
For example, the kind of information that this sort of testing may give you, includes (to look at some “popular” SNPs):
- rs53576 in the oxytocin receptor influences social behavior and personality
- rs7412 and rs429358 can raise the risk of Alzheimer’s disease by more than 10x
- rs6152 can influence baldness
- rs333 resistance to HIV
- rs1800497 in a dopamine receptor may influence the sense of pleasure
- rs1805007 determines red hair and sensitivity to anesthetics
- rs9939609 triggers obesity and type-2 diabetes
- rs662799 prevents weight gain from high fat diets
- rs12255372 linked to type-2 diabetes and breast cancer
- rs1799971 makes alcohol cravings stronger
- rs17822931 determines earwax, sweating and body odor
- rs1333049 coronary heart disease
- rs1051730 and rs3750344 nicotine dependence
- rs4988235 lactose intolerance
(You can learn about these and more than 100,000 other SNPs at SNPedia.com)
I don’t know what SNPs I have, and am disinclined to look them up one by one!
The first step to knowing, is to get your DNA out of your body and into a genetic testing service. This is usually done by saliva or blood sample. This writer got hers done many years ago by 23andMe and was very happy with that service, but there are plenty of other options.
Healthline did an independent review of the most popular companies, so you might like to check out:
Healthline: Best DNA Testing Kits of 2023
Those companies will give you some basic information, such as “6x higher breast cancer risk” or “3x lower age-related macular degeneration risk” etc.
However, to really get bang-for-buck, what you want to do next is:
- Get your raw genetic data (the companies above should provide it); this will probably look like a big text file full of As, Cs, Gs, and Ts, but it make take another form.
- Upload it to Promethease. When this writer got hers done , the cost was $2; that price has now gone up to a whopping $12.
- You will then get a report that will cross-reference your data with everything known about SNPs, and give a supremely comprehensive, readable-to-the-human-eye, explanation of what it all means for you—from much more specific health risk prognostics, to more trivial things like whether you can roll your tongue or smell decomposed asparagus metabolites in urine.
A note on privacy: anything you upload to Promethease will be anonymized, and/but in doing so, you consent to it going into the grand scientific open-source bank of “things we know about the human genome”, and thus contribute to the overall sample size of genetic data.
In our opinion, it means you’re doing your bit for science, without personal risk. But your opinion may differ, and that’s your decision to make.
Lastly, on the pros and cons of pharmacogenetic testing specifically:

Maximize Your Misery! (7 Great Methods)
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.
Let’s imagine that instead of being healthily fulfilled in life, you wanted to spend your days as miserable as possible. What should you do?
Here are a few pointers:
Stay still
Avoid physical activity and/or outdoor exposure, to avoid any mood-lifting neurochemicals. In fact, remain indoors as much as possible, preferably in the same room.
If you want to absolutely maximize your misery, make your bedroom the sole space for all activities that it’s possible to do there.
Disrupt your sleep
Keep an irregular sleep schedule by varying your bedtime and wake-up times frequently. Sleep in as much as possible, and make up for it by staying up late to ensure ongoing exhaustion.
Maximize screentime
Use digital entertainment as much as possible to distract you from meaningful activities and rest—as a bonus, this will also help you to avoid self-reflection.
Begin and end your day with a device in hand.
Fuel negative emotions
If you’re going to focus on something, focus on problems you cannot control, to stoke the fires of anger and angst.
A good way of doing this is by staying informed about distressing events, while avoiding meaningful actions to address them. Contribute only in token gestures, and then lament the lack of change.
Follow your impulses
Act on short-term desires without considering long-term consequences, while avoiding behaviors that you know might improve your mood or wellbeing.
Trust that doing the same things that have not previously resulted in happiness, will continue to reliably deliver unhappiness.
Set goals to miss
It’s important that your goals should be vague, and overly ambitious in their scope and/or deliverability. Ideally you should also disregard any preparatory work that a person would normally do before embarking on such a project.
Bonus tip: you can further sabotage any chances of progress, by waiting for motivation to strike before you take any action.
Pursue happiness
Focus on chasing happiness itself, instead of improving your situation or skills. Treat happiness as an end goal, instead of a by-product of worthwhile activities.
