The book does kick off with a section that didn’t age well—he talks of the stress induced globally by the Spanish Flu pandemic of 1918, and how that kind of thing just doesn’t happen any more. Today, we have much less existentially dangerous stressors!
However, the fact we went and had another pandemic really only adds weight to the general arguments of the book, rather than detracting.
We are consistently beset by “the slings and arrows of outrageous fortune” as Shakespeare would put it, and there’s a reason (or twenty) why many people go grocery-shopping with the cortisol levels of someone being hunted for sport.
So, why don’t zebras get ulcers, as they actually are hunted for food?
They don’t have rent to pay or a mortgage, they don’t have taxes, or traffic, or a broken washing machine, or a project due in the morning. Their problems come one at a time. They have a useful stress response to a stressful situation (say, being chased by lions), and when the danger is over, they go back to grazing. They have time to recover.
For us, we are (usually) not being chased by lions. But we have everything else, constantly, around the clock. So, how to fix that?
Dr. Sapolsky comprehensively describes our physiological responses to stress in quite different terms than many. By reframing stress responses as part of the homeostatic system—trying to get the body back into balance—we find a solution, or rather: ways to help our bodies recover.
The style is “pop-science” and is very accessible for the lay reader while still clearly coming from a top-level academic who is neck-deep in neuroendocrinological research. Best of both worlds!
Bottom line: if you try to take very day at a time, but sometimes several days gang up on you at once, and you’d like to learn more about what happens inside you as a result and how to fix that, this book is for you!

Lycopene’s Benefits For The Gut, Heart, Brain, & More
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.
What Doesn’t Lycopene Do?
Lycopene is an antioxidant carotenoid famously found in tomatoes; it actually appears in even higher levels in watermelon, though. If you are going to get it from tomato, know that cooking improves the lycopene content rather than removing it (watermelon, on the other hand, can be enjoyed as-is and already has the higher lycopene content).
Antioxidant properties
Let’s reiterate the obvious first, for the sake of being methodical and adding a source. Lycopene is a potent antioxidant with multiple health benefits:
Lycopene: A Potent Antioxidant with Multiple Health Benefits
…and as such, it does all the things you might reasonably expect and antioxidant to do. For example…
Anti-inflammatory properties
In particular, it regulates macrophage activity, reducing inflammation while improving immune response:
Lycopene Regulates Macrophage Immune Response through the Autophagy Pathway Mediated by RIPK1
As can be expected of most antioxidants and anti-inflammatory agents, it also has…
Anticancer properties
Scientific papers tend to be “per cancer type”, so we’re just going to give one example, but there’s pretty much evidence for its utility against most if not all types of cancer. We’re picking prostate cancer though, as it’s one that’s been studied the most in the context of lycopene intake—in this study, for example, it was found that men who enjoyed at least two servings of lycopene-rich tomato sauce per week were 30% less likely to develop prostate cancer than those who didn’t:
Dietary lycopene intake and risk of prostate cancer defined by ERG protein expression
If you’d like to see something more general, however, then check out:
Potential Use of Tomato Peel, a Rich Source of Lycopene, for Cancer Treatment
It also fights Candida albicans
Ok, this is not (usually) so life-and-death as cancer, but reducing our C. albicans content (specifically: in our gut) has a lot of knock-on effects for other aspects of our health, so this isn’t one to overlook:
The title does not make this clear, but yes: this does mean it has an antifungal effect. We mention this because often cellular apoptosis is good for an overall organism, but in this case, it simply kills the Candida.
It’s good for the heart
A lot of studies focus just on triglyceride markers (which lycopene improves), but more tellingly, here’s a 10-year observational study in which diets rich in lycopene were associated to a 17–26% lower risk of heart disease:
Relationship of lycopene intake and consumption of tomato products to incident CVD
…and a 39% overall reduced mortality in, well, we’ll let the study title tell it:
…which means also:
It’s good for the brain
As a general rule of thumb, what’s good for the heart is good for the brain (because the brain needs healthy blood flow to stay healthy, and is especially vulnerable when it doesn’t get that), and in this case that rule of thumb is also borne out by the post hoc evidence, specifically yielding a 31% decreased incidence of stroke:
Dietary and circulating lycopene and stroke risk: a meta-analysis of prospective studies
Is it safe?
As a common food product, it is considered very safe.
If you drink nothing but tomato juice all day for a long time, your skin will take on a reddish hue, which will go away if you stop getting all your daily water intake in tomato juice.
In all likelihood, even if you went to extremes, you would get sick from the excess of vitamin A (generally present in the same foods) sooner than you’d get sick from the excess of lycopene.
Want to try some?
We don’t sell it, and also we recommend simply enjoying tomatoes, watermelons, etc, but if you do want a supplement, here’s an example product on Amazon

Voluntary assisted dying is different to suicide. But federal laws conflate them and restrict access to telehealth
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.
Voluntary assisted dying is now lawful in every Australian state and will soon begin in the Australian Capital Territory.
However, it’s illegal to discuss it via telehealth. That means people who live in rural and remote areas, or those who can’t physically go to see a doctor, may not be able to access the scheme.
A federal private members bill, introduced to parliament last week, aims to change this. So what’s proposed and why is it needed?
What’s wrong with the current laws?
Voluntary assisted dying doesn’t meet the definition of suicide under state laws.
But the Commonwealth Criminal Code prohibits the discussion or dissemination of suicide-related material electronically.
This opens doctors to the risk of criminal prosecution if they discuss voluntary assisted dying via telehealth.
Successive Commonwealth attorneys-general have failed to address the conflict between federal and state laws, despite persistent calls from state attorneys-general for necessary clarity.
This eventually led to voluntary assistant dying doctor Nicholas Carr calling on the Federal Court of Australia to resolve this conflict. Carr sought a declaration to exclude voluntary assisted dying from the definition of suicide under the Criminal Code.
In November, the court declared voluntary assisted dying was considered suicide for the purpose of the Criminal Code. This meant doctors across Australia were prohibited from using telehealth services for voluntary assisted dying consultations.
Last week, independent federal MP Kate Chaney introduced a private members bill to create an exemption for voluntary assisted dying by excluding it as suicide for the purpose of the Criminal Code. Here’s why it’s needed.
Not all patients can physically see a doctor
Defining voluntary assisted dying as suicide in the Criminal Code disproportionately impacts people living in regional and remote areas. People in the country rely on the use of “carriage services”, such as phone and video consultations, to avoid travelling long distances to consult their doctor.
Other people with terminal illnesses, whether in regional or urban areas, may be suffering intolerably and unable to physically attend appointments with doctors.
The prohibition against telehealth goes against the principles of voluntary assisted dying, which are to minimise suffering, maximise quality of life and promote autonomy.
Doctors don’t want to be involved in ‘suicide’
Equating voluntary assisted dying with suicide has a direct impact on doctors, who fear criminal prosecution due to the prohibition against using telehealth.
Some doctors may decide not to help patients who choose voluntary assisted dying, leaving patients in a state of limbo.
The number of doctors actively participating in voluntary assisted dying is already low. The majority of doctors are located in metropolitan areas or major regional centres, leaving some locations with very few doctors participating in voluntary assisted dying.
It misclassifies deaths
In state law, people dying under voluntary assisted dying have the cause of their death registered as “the disease, illness or medical condition that was the grounds for a person to access voluntary assisted dying”, while the manner of dying is recorded as voluntary assisted dying.
In contrast, only coroners in each state and territory can make a finding of suicide as a cause of death.
In 2017, voluntary assisted dying was defined in the Coroners Act 2008 (Vic) as not a reportable death, and thus not suicide.
The language of suicide is inappropriate for explaining how people make a decision to die with dignity under the lawful practice of voluntary assisted dying.
There is ongoing taboo and stigma attached to suicide. People who opt for and are lawfully eligible to access voluntary assisted dying should not be tainted with the taboo that currently surrounds suicide.
So what is the solution?
The only way to remedy this problem is for the federal government to create an exemption in the Criminal Code to allow telehealth appointments to discuss voluntary assisted dying.
Chaney’s private member’s bill is yet to be debated in federal parliament.
If it’s unsuccessful, the Commonwealth attorney-general should pass regulations to exempt voluntary assisted dying as suicide.
A cooperative approach to resolve this conflict of laws is necessary to ensure doctors don’t risk prosecution for assisting eligible people to access voluntary assisted dying, regional and remote patients have access to voluntary assisted dying, families don’t suffer consequences for the erroneous classification of voluntary assisted dying as suicide, and people accessing voluntary assisted dying are not shrouded with the taboo of suicide when accessing a lawful practice to die with dignity.
Failure to change this will cause unnecessary suffering for patients and doctors alike.

Procrastination, and how to pay off the to-do list debt

Procrastination, and how pay off the to-do list debt
Sometimes we procrastinate because we feel overwhelmed by the mountain of things we are supposed to be doing. If you look at your to-do list and it shows 60 overdue items, it’s little wonder if you want to bury your head in the sand!
“What difference does it make if I do one of these things now; I will still have 59 which feels as bad as having 60”
So, treat it like you might a financial debt, and make a repayment plan. Now, instead of 60 overdue items today, you have 1/day for the next 60 days, or 2/day for the next 30 days, or 3/day for the next 20 days, etc. Obviously, you may need to work out whether some are greater temporal priorities and if so, bump those to the top of the list. But don’t sweat the minutiae; your list doesn’t have to be perfectly ordered, just broadly have more urgent things to the top and less urgent things to the bottom.
Note: this repayment plan means having set repayment dates.
Up front, sit down and assign each item a specific calendar date on which you will do that thing.
This is not a deadline! It is your schedule. You’ll not try to do it sooner, and you won’t postpone it for later. You will just do that item on that date.
A productivity app like ToDoist can help with this, but paper is fine too.
What’s important here, psychologically, is that each day you’re looking not at 60 things and doing the top item; you’re just looking at today’s item (only!) and doing it.
Debt Reduction/Cancellation
Much like you might manage a financial debt, you can also look to see if any of your debts could be reduced or cancelled.
We wrote previously about the “Getting Things Done” system. It’s a very good system if you want to do that; if not, no worries, but you might at least want to borrow this one idea….
Sort your items into:
Do / Defer / Delegate / Ditch
- Do: if it can be done in under 2 minutes, do it now.
- Defer: defer the item to a specific calendar date (per the repayment plan idea we just talked about)
- Delegate: could this item be done by someone else? Get it off your plate if you reasonably can.
- Ditch: sometimes, it’s ok to realize “you know what, this isn’t that important to me anymore” and scratch it from the list.
As a last resort, consider declaring bankruptcy
Towards the end of the dot-com boom, there was a fellow who unintentionally got his 5 minutes of viral fame for “declaring email bankruptcy”.
Basically, he publicly declared that his email backlog had got so far out of hand that he would now not reply to emails from before the declaration.
He pledged to keep on top of new emails only from that point onwards; a fresh start.
We can’t comment on whether he then did, but if you need a fresh start, that can be one way to get it!
In closing…
Procrastination is not usually a matter of laziness, it’s usually a matter of overwhelm. Hopefully the above approach will help reframe things, and make things more manageable.
Sometimes procrastination is a matter of perfectionism, and not starting on tasks because we worry we won’t do them well enough, and so we get stuck in a pseudo-preparation rut. If that’s the case, our previous main feature on perfectionism may help:

How Not to Diet – by Dr. Michael Greger
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’ve talked before about Dr. Greger’s famous “How Not To Die” book, and we love it and recommend it… But… It is, primarily, a large, dry textbook. Full of incredibly good science and information about what is statistically most likely to kill us and how to avoid that… but it’s not the most accessible.
“How Not To Diet“, on the other hand, is a diet book, is very readable, and assumes the reader would simply like to know how to healthily lose weight.
By focussing on this one problem, rather than the many (admittedly important) mortality risks, the reading is a lot easier and lighter. And, because it’s still Dr. Greger advocating for the same diet, you’ll still get to reduce all those all-cause mortality risks. You won’t be reading about them in this book; it will now just be a happy side effect.
While in “How Not To Die”, Dr. Greger looked at what was killing people and then tackled those problems, here he’s taken the same approach to just one problem… Obesity.
So, he looks at what is causing people to be overweight, and methodically tackles those problems.
We’ll not list them all here—there are many, and this is a book review, not a book summary. But suffice it to say, the work is comprehensive.
Bottom line: this book methodically and clinically (lots of science!) looks at what makes us overweight… And tackles those problems one by one, giving us a diet optimized for good health and weight loss. If you’d like to shed a few pounds in a healthy, sustainable way (that just happens to significantly reduce mortality risk from other causes too) then this is a great book for you!

Shame and blame can create barriers to vaccination
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.
Understanding the stigma surrounding infectious diseases like HIV and mpox may help community health workers break down barriers that hinder access to care.
Looking back in history can provide valuable lessons to confront stigma in health care today, especially toward Black, Latine, LGBTQ+, and other historically underserved communities disproportionately affected by COVID-19 and HIV.
Public Good News spoke with Sam Brown, HIV prevention and wellness program manager at Civic Heart, a community-based organization in Houston’s historic Third Ward, to understand the effects of stigma around sexual health and vaccine uptake.
Brown shared more about Civic Heart’s efforts to provide free confidential testing for sexually transmitted infections, counseling and referrals, and information about COVID-19, flu, and mpox vaccinations, as well as the lessons they’re learning as they strive for vaccine equity.
Here’s what Brown said.
[Editor’s note: This content has been edited for clarity and length.]
PGN: Some people on social media have spread the myth that vaccines cause AIDS or other immune deficiencies when the opposite is true: Vaccines strengthen our immune systems to help protect against disease. Despite being frequently debunked, how do false claims like these impact the communities you serve?
Sam Brown: Misinformation like that is so hard to combat. And it makes the work and the path to overall community health hard because people will believe it. In the work that we do, 80 percent of it is changing people’s perspective on something they thought they knew.
You know, people don’t even transmit AIDS. People transmit HIV. So, a vaccine causing immunodeficiency doesn’t make sense.
With the communities we serve, we might have a person that will believe the myth, and because they believe it, they won’t get vaccinated. Then later, they may test positive for COVID-19.
And depending on social determinants of health, it can impact them in a whole heap of ways: That person is now missing work, they’re not able to provide for their family—if they have a family. It’s this mindset that can impact a person’s life, their income, their ability to function.
So, to not take advantage of something like a vaccine that’s affordable, or free for the most part, just because of misinformation or a misunderstanding—that’s detrimental, you know.
For example, when we talk to people in the community, many don’t know that they can get mpox from their pet, or that it’s zoonotic—that means that it can be transferred between different species or different beings, from animals to people. I see a lot of surprise and shock [when people learn this].
It’s difficult because we have to fight the misinformation and the stigma that comes with it. And it can be a big barrier.
People misunderstand. [They] think that “this is something that gay people or the LGBTQ+ community get,” which is stigmatizing and comes off as blaming. And blaming is the thing that leads us to be misinformed.
PGN: In the last couple years, your organization’s HIV Wellness program has taken on promoting COVID-19, flu, and mpox vaccines to the communities you serve. How do you navigate conversations between sexual health and infectious diseases? Can you share more about your messaging strategies?
S.B.: As we promoted positive sexual health and HIV prevention, we saw people were tired of hearing about HIV. They were tired of hearing about how PrEP works, or how to prevent HIV.
But, when we had an outbreak of syphilis in Houston just last year, people were more inclined to test because of the severity of the outbreak.
So, what our team learned is that sometimes you have to change the message to get people what they need.
We changed our message to highlight more syphilis information and saw that we were able to get more people tested for HIV because we correlated how syphilis and HIV are connected and how a person can be susceptible to both.
Using messages that the community wants and pairing them with what the community needs has been better for us. And we see that same thing with COVID-19, the flu, and RSV. Sometimes you just can’t be married to a message. We’ve had to be flexible to meet our clients where they are to help them move from unsafe practices to practices that are healthy and good for them and their communities.
PGN: You’ve mentioned how hard it is to combat stigma in your work. How do you effectively address it when talking to people one-on-one?
S.B.: What I understand is that no one wants to feel shame. What I see people respond to is, “Here’s an opportunity to do something different. Maybe there was information that you didn’t know that caused you to make a bad decision. And now here’s an opportunity to gain information so that you can make a better decision.”
People want to do what they want to do; they want to live how they want to live. And we all should be able to do that as long as it’s not hurting anyone, but also being responsible enough to understand that, you know, COVID-19 is here.
So, instead of shaming and blaming, it’s best to make yourself aware and understand what it is and how to treat it. Because the real enemy is the virus—it’s the infection, not the people.
When we do our work, we want to make sure that we come from a strengths-based approach. We always look at what a client can do, what that client has. We want to make sure that we’re empowering them from that point. So, even if they choose not to prioritize our message right now, we can’t take that personally. We’ll just use it as a chance to try a new way of framing it to help people understand what we’re trying to say.
And sometimes that can be difficult, even for organizations. But getting past that difficulty comes with a greater opportunity to impact someone else.

Clams vs Oysters – 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 clams to oysters, we picked the clams.
Why?
Considering the macros first, clams have more than 2x the protein, while oysters have nearly 2x the fat, of which, a little over 5x the saturated fat. So, in all accounts, clam is the winner here.
In terms of vitamins, clams have more of vitamins A, B1, B2, B3, B5, B6, B7, B9, B12, and C, while oysters are not higher in any vitamins. Another win for clams.
The category of minerals is more balanced; clams are higher in manganese, phosphorus, potassium, and selenium, while oysters are higher in copper, iron, magnesium, and zinc. This makes for a 4:4 tie, though it’s worth noting that the margin of difference for zinc is very large, so that can be an argument for oysters.
Nevertheless, adding up the sections makes for a clear win for clams.
A quick aside on “are oysters an aphrodisiac?”:
That zinc content is probably largely responsible for oysters’ reputation as an aphrodisiac, and zinc is important in the synthesis of both estrogen and testosterone. However, as the synthesis is not instant, and those sex hormones rise most in the morning (around 8am to 9am), to enjoy aphrodisiac benefits it’d be more sensible, on a biochemical level, to eat oysters one day, and then have morning sex the next day when those hormones are peaking. That said, while testosterone is the main driver of male libido, progesterone is usually more relevant for women’s, and unlike estrogen, progesterone usually peaks around 10pm to 2am, and is uninfluenced by having just eaten oysters.
So, in what way, if any, could oysters be responsible for libido in women? Well, the zinc is still important in energy metabolism, so that’s a factor, and also, we might hypothesize that oysters’ high saturated fat and cholesterol content may increase blood pressure which, while not fabulous for the health in general, may be considered desirable in the bedroom since the clitoris is anatomically analogous to the penis, and—while estrogen vs testosterone makes differences to the nervous system down there that are beyond the scope of today’s article—also enjoys localized increased blood pressure (and thus, a flushing response and resultant engorgement) during arousal.
