We know that meditation helps people to relax, but what more than that?This book explores the available science.
We say “explore the available science”, but it’d be remiss of us not to note that the authors have also expanded the available science, conducting research in their own lab.
From stress tests and EEGs to attention tests and fMRIs, this book looks at the hard science of what different kinds of meditation do to the brain. Not just in terms of brain state, either, but gradual cumulative anatomical changes, too. Powerful stuff!
The style is very pop-science in presentation, easily comprehensible to all. Be aware though that this is an “if this, then that” book of science, not a how-to manual. If you want to learn to meditate, this isn’t the book for that.
Bottom line: if you’d like to understand more about how different kinds of meditation affect the brain differently, this is the book for you.

Study links microplastics with human health problems – but there’s still a lot we don’t know
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.
Mark Patrick Taylor, Macquarie University and Scott P. Wilson, Macquarie University
A recent study published in the prestigious New England Journal of Medicine has linked microplastics with risk to human health.
The study involved patients in Italy who had a condition called carotid artery plaque, where plaque builds up in arteries, potentially blocking blood flow. The researchers analysed plaque specimens from these patients.
They found those with carotid artery plaque who had microplastics and nanoplastics in their plaque had a higher risk of heart attack, stroke, or death (compared with carotid artery plaque patients who didn’t have any micro- or nanoplastics detected in their plaque specimens).
Importantly, the researchers didn’t find the micro- and nanoplastics caused the higher risk, only that it was correlated with it.
So, what are we to make of the new findings? And how does it fit with the broader evidence about microplastics in our environment and our bodies?
What are microplastics?
Microplastics are plastic particles less than five millimetres across. Nanoplastics are less than one micron in size (1,000 microns is equal to one millimetre). The precise size classifications are still a matter of debate.
Microplastics and nanoplastics are created when everyday products – including clothes, food and beverage packaging, home furnishings, plastic bags, toys and toiletries – degrade. Many personal care products contain microsplastics in the form of microbeads.
Plastic is also used widely in agriculture, and can degrade over time into microplastics and nanoplastics.
These particles are made up of common polymers such as polyethylene, polypropylene, polystyrene and polyvinyl chloride. The constituent chemical of polyvinyl chloride, vinyl chloride, is considered carcinogenic by the US Environmental Protection Agency.
Of course, the actual risk of harm depends on your level of exposure. As toxicologists are fond of saying, it’s the dose that makes the poison, so we need to be careful to not over-interpret emerging research.
A closer look at the study
This new study in the New England Journal of Medicine was a small cohort, initially comprising 304 patients. But only 257 completed the follow-up part of the study 34 months later.
The study had a number of limitations. The first is the findings related only to asymptomatic patients undergoing carotid endarterectomy (a procedure to remove carotid artery plaque). This means the findings might not be applicable to the wider population.
The authors also point out that while exposure to microplastics and nanoplastics has been likely increasing in recent decades, heart disease rates have been falling.
That said, the fact so many people in the study had detectable levels of microplastics in their body is notable. The researchers found detectable levels of polyethylene and polyvinyl chloride (two types of plastic) in excised carotid plaque from 58% and 12% of patients, respectively.
These patients were more likely to be younger men with diabetes or heart disease and a history of smoking. There was no substantive difference in where the patients lived.
Inflammation markers in plaque samples were more elevated in patients with detectable levels of microplastics and nanoplastics versus those without.
And, then there’s the headline finding: patients with microplastics and nanoplastics in their plaque had a higher risk of having what doctors call “a primary end point event” (non-fatal heart attack, non-fatal stroke, or death from any cause) than those who did not present with microplastics and nanoplastics in their plaque.
The authors of the study note their results “do not prove causality”.
However, it would be remiss not to be cautious. The history of environmental health is replete with examples of what were initially considered suspect chemicals that avoided proper regulation because of what the US National Research Council refers to as the “untested-chemical assumption”. This assumption arises where there is an absence of research demonstrating adverse effects, which obviates the requirement for regulatory action.
In general, more research is required to find out whether or not microplastics cause harm to human health. Until this evidence exists, we should adopt the precautionary principle; absence of evidence should not be taken as evidence of absence.
Global and local action
Exposure to microplastics in our home, work and outdoor environments is inevitable. Governments across the globe have started to acknowledge we must intervene.
The Global Plastics Treaty will be enacted by 175 nations from 2025. The treaty is designed, among other things, to limit microplastic exposure globally. Burdens are greatest especially in children and especially those in low-middle income nations.
In Australia, legislation ending single use plastics will help. So too will the increased rollout of container deposit schemes that include plastic bottles.
Microplastics pollution is an area that requires a collaborative approach between researchers, civil societies, industry and government. We believe the formation of a “microplastics national council” would help formulate and co-ordinate strategies to tackle this issue.
Little things matter. Small actions by individuals can also translate to significant overall environmental and human health benefits.
Choosing natural materials, fabrics, and utensils not made of plastic and disposing of waste thoughtfully and appropriately – including recycling wherever possible – is helpful.

Eat All You Want (But Wisely)
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.
Some Surprising Truths About Hunger And Satiety
This is Dr. Barbara Rolls. She’s Professor and Guthrie Chair in Nutritional Sciences, and Director of the Laboratory for the Study of Human Ingestive Behavior at Pennsylvania State University, after graduating herself from Oxford and Cambridge (yes, both). Her “awards and honors” take up four A4 pages, so we won’t list them all here.
Most importantly, she’s an expert on hunger, satiety, and eating behavior in general.
What does she want us to know?
First and foremost: you cannot starve yourself thin, unless you literally starve yourself to death.
What this is about: any weight lost due to malnutrition (“not eating enough” is malnutrition) will always go back on once food becomes available. So unless you die first (not a great health plan), merely restricting good will always result in “yo-yo dieting”.
So, to avoid putting the weight back on and feeling miserable every day along the way… You need to eat as much as you feel you need.
But, there’s a trick here (it’s about making you genuinely feel you need less)!
Your body is an instrument—so play it
Your body is the tool you use to accomplish pretty much anything you do. It is, in large part, at your command. Then there are other parts you can’t control directly.
Dr. Rolls advises taking advantage of the fact that much of your body is a mindless machine that will simply follow instructions given.
That includes instructions like “feel hungry” or “feel full”. But how to choose those?
Volume matters
An important part of our satiety signalling is based on a physical sensation of fullness. This, by the way, is why bariatric surgery (making a stomach a small fraction of the size it was before) works. It’s not that people can’t eat more (the stomach is stretchy and can also be filled repeatedly), it’s that they don’t want to eat more because the pressure sensors around the stomach feel full, and signal the hormone leptin to tell the brain we’re full now.
Now consider:
- On the one hand, 20 grapes, fresh and bursting with flavor
- On the other hand, 20 raisins (so, dried grapes), containing the same calories
Which do you think will get the leptin flowing sooner? Of course, the fresh grapes, because of the volume.
So if you’ve ever seen those photos that show two foods side by side with the same number of calories but one is much larger (say, a small slice of pizza or a big salad), it’s not quite the cheap trick that it might have appeared.
Or rather… It is a cheap trick; it’s just a cheap trick that works because your stomach is quite a simple organ.
So, Dr. Rolls’ advice: generally speaking, go for voluminous food. Fruit is great from this, because there’s so much water. Air-popped popcorn also works great. Vegetables, too.
Water matters, but differently than you might think
A well-known trick is to drink water before and with a meal. That’s good, it’s good to be hydrated. However, it can be better. Dr. Rolls did an experiment:
The design:
❝Subjects received 1 of 3 isoenergetic (1128 kJ) preloads 17 min before lunch on 3 d and no preload on 1 d.
The preloads consisted of 1) chicken rice casserole, 2) chicken rice casserole served with a glass of water (356 g), and 3) chicken rice soup.
The soup contained the same ingredients (type and amount) as the casserole that was served with water.❞
The results:
❝Decreasing the energy density of and increasing the volume of the preload by adding water to it significantly increased fullness and reduced hunger and subsequent energy intake at lunch.
The equivalent amount of water served as a beverage with a food did not affect satiety.❞
The conclusion:
❝Consuming foods with a high water content more effectively reduced subsequent energy intake than did drinking water with food.❞
You can read the study in full (it’s a worthwhile read!) here:
Water incorporated into a food but not served with a food decreases energy intake in lean women
Protein matters
With all those fruits and vegetables and water, you may be wondering Dr. Rolls’ stance on proteins. It’s simple: protein is an appetite suppressant.
However, it takes about 20 minutes to signal the brain about that, so having some protein in a starter (if like this writer, you’re the cook of the household, a great option is to enjoy a small portion of nuts while cooking!) gets that clock ticking, to signal satiety sooner.
It may also help in other ways:

As for other foods that can suppress appetite, by the way, you might like;
25 Foods That Act As Natural Appetite Suppressants
Variety matters, and in ways other than you might think
A wide variety of foods (especially: a wide variety of plants) in one’s diet is well recognized as a key to a good balanced diet.
However…
A wide variety of dishes at the table, meanwhile, promotes greater consumption of food.
Dr. Rolls did a study on this too, a while ago now (you’ll see how old it is) but the science seems robust:
Variety in a Meal Enhances Food Intake in Man
Notwithstanding the title, it wasnot about a man (that was just how scientists wrote in ye ancient times of 1981). The test subjects were, in order: rats, cats, a mixed group of men and women, the same group again, and then a different group of all women.
So, Dr. Rolls’ advice is: it’s better to have one 20-ingredient dish, than 10 dishes with 20 ingredients between them.
Sorry! We love tapas and buffets too, but that’s the science!
So, “one-pot” meals are king in this regard; even if you serve it with one side (reasonable), that’s still only two dishes, which is pretty good going.
Note that the most delicious many-ingredient stir-fries and similar dishes from around the world also fall into this category!

An Unexpected Extra Threat Of Alcohol

If You Could Use Some Exotic Booze…
…then for health reasons, we’re going to have to say “nay”.
We’ve written about alcohol before, and needless to say, it’s not good:
(the answer is “no, we cannot”)
In fact, the WHO (which unlike government regulatory bodies setting “safe” limits on drinking, makes no profit from taxes on alcohol sales) has declared that “the only safe amount of alcohol is zero”:
WHO: No level of alcohol consumption is safe for our health
Up there, where the air is rarefied…
If you’re flying somewhere this summer (Sinatra-style flying honeymoon or otherwise), you might want to skip the alcohol even if you normally do imbibe, because:
❝…even in young and healthy individuals, the combination of alcohol intake with sleeping under hypobaric conditions poses a considerable strain on the cardiac system and might lead to exacerbation of symptoms in patients with cardiac or pulmonary diseases.
These effects might be even greater in older people; cardiovascular symptoms have a prevalence of 7% of inflight medical emergencies, with cardiac arrest causing 58% of aircraft diversions.❞
Source: Alcohol plus cabin pressure at higher altitude may threaten sleeping plane passengers’ heart health
The experiment divided subjects into a control group and a study group; the study group were placed in simulated cabin pressure as though at altitude, which found, when giving some of them two small(we’re talking the kind given on flights) alcoholic drinks:
❝The combination of alcohol and simulated cabin pressure at cruising altitude prompted a fall in SpO2 to an average of just over 85% and a compensatory increase in heart rate to an average of nearly 88 beats/minute during sleep.❞
In contrast, that was 77 beats/minute for those who had alcohol but weren’t at altitude pressure, or 64 beats/minute for those who neither drank nor were at altitude pressure.
Lots more metrics were recorded and the study is interesting to read; if you’ve ever slept on a plane and thought “that sleep was not restful at all”, then know: it wasn’t just the seat’s fault, nor the engine, nor the recycled nature of the air—it was the reduced pressure causing hypoxia (defined as having oxygen levels lower than the healthy clinical norm of 90%) and almost halving your sleep’s effectiveness for a less than 10% drop in available oxygen in the blood (the sleepers not at altitude pressure averaged 96% SpO2, compared to the 85% at altitude).
We say “almost halving” because the deep sleep phase of sleep was reduced from 84 minutes (control) to 67.5 minutes at altitude without alcohol, or 46.5 minutes at altitude with alcohol.
Again, this was a pressure cabin in a lab—so this wasn’t about the other conditions of an airplane (seats, engine hundreds of other people, etc).
Which means: in an actual airplane it’s probably even worse.
Oh, and the study participants? All healthy individuals aged 18–40, so again probably worse for those older (or younger) than that range, or with existing health conditions!

Traveling To Die: The Latest Form of Medical Tourism
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.
In the 18 months after Francine Milano was diagnosed with a recurrence of the ovarian cancer she thought she’d beaten 20 years ago, she traveled twice from her home in Pennsylvania to Vermont. She went not to ski, hike, or leaf-peep, but to arrange to die.
“I really wanted to take control over how I left this world,” said the 61-year-old who lives in Lancaster. “I decided that this was an option for me.”
Dying with medical assistance wasn’t an option when Milano learned in early 2023 that her disease was incurable. At that point, she would have had to travel to Switzerland — or live in the District of Columbia or one of the 10 states where medical aid in dying was legal.
But Vermont lifted its residency requirement in May 2023, followed by Oregon two months later. (Montana effectively allows aid in dying through a 2009 court decision, but that ruling doesn’t spell out rules around residency. And though New York and California recently considered legislation that would allow out-of-staters to secure aid in dying, neither provision passed.)
Despite the limited options and the challenges — such as finding doctors in a new state, figuring out where to die, and traveling when too sick to walk to the next room, let alone climb into a car — dozens have made the trek to the two states that have opened their doors to terminally ill nonresidents seeking aid in dying.
At least 26 people have traveled to Vermont to die, representing nearly 25% of the reported assisted deaths in the state from May 2023 through this June, according to the Vermont Department of Health. In Oregon, 23 out-of-state residents died using medical assistance in 2023, just over 6% of the state total, according to the Oregon Health Authority.
Oncologist Charles Blanke, whose clinic in Portland is devoted to end-of-life care, said he thinks that Oregon’s total is likely an undercount and he expects the numbers to grow. Over the past year, he said, he’s seen two to four out-of-state patients a week — about one-quarter of his practice — and fielded calls from across the U.S., including New York, the Carolinas, Florida, and “tons from Texas.” But just because patients are willing to travel doesn’t mean it’s easy or that they get their desired outcome.
“The law is pretty strict about what has to be done,” Blanke said.
As in other states that allow what some call physician-assisted death or assisted suicide, Oregon and Vermont require patients to be assessed by two doctors. Patients must have less than six months to live, be mentally and cognitively sound, and be physically able to ingest the drugs to end their lives. Charts and records must be reviewed in the state; neglecting to do so constitutes practicing medicine out of state, which violates medical licensing requirements. For the same reason, the patients must be in the state for the initial exam, when they request the drugs, and when they ingest them.
State legislatures impose those restrictions as safeguards — to balance the rights of patients seeking aid in dying with a legislative imperative not to pass laws that are harmful to anyone, said Peg Sandeen, CEO of the group Death With Dignity. Like many aid-in-dying advocates, however, she said such rules create undue burdens for people who are already suffering.
Diana Barnard, a Vermont palliative care physician, said some patients cannot even come for their appointments. “They end up being sick or not feeling like traveling, so there’s rescheduling involved,” she said. “It’s asking people to use a significant part of their energy to come here when they really deserve to have the option closer to home.”
Those opposed to aid in dying include religious groups that say taking a life is immoral, and medical practitioners who argue their job is to make people more comfortable at the end of life, not to end the life itself.
Anthropologist Anita Hannig, who interviewed dozens of terminally ill patients while researching her 2022 book, “The Day I Die: The Untold Story of Assisted Dying in America,” said she doesn’t expect federal legislation to settle the issue anytime soon. As the Supreme Court did with abortion in 2022, it ruled assisted dying to be a states’ rights issue in 1997.
During the 2023-24 legislative sessions, 19 states (including Milano’s home state of Pennsylvania) considered aid-in-dying legislation, according to the advocacy group Compassion & Choices. Delaware was the sole state to pass it, but the governor has yet to act on it.
Sandeen said that many states initially pass restrictive laws — requiring 21-day wait times and psychiatric evaluations, for instance — only to eventually repeal provisions that prove unduly onerous. That makes her optimistic that more states will eventually follow Vermont and Oregon, she said.
Milano would have preferred to travel to neighboring New Jersey, where aid in dying has been legal since 2019, but its residency requirement made that a nonstarter. And though Oregon has more providers than the largely rural state of Vermont, Milano opted for the nine-hour car ride to Burlington because it was less physically and financially draining than a cross-country trip.
The logistics were key because Milano knew she’d have to return. When she traveled to Vermont in May 2023 with her husband and her brother, she wasn’t near death. She figured that the next time she was in Vermont, it would be to request the medication. Then she’d have to wait 15 days to receive it.
The waiting period is standard to ensure that a person has what Barnard calls “thoughtful time to contemplate the decision,” although she said most have done that long before. Some states have shortened the period or, like Oregon, have a waiver option.
That waiting period can be hard on patients, on top of being away from their health care team, home, and family. Blanke said he has seen as many as 25 relatives attend the death of an Oregon resident, but out-of-staters usually bring only one person. And while finding a place to die can be a problem for Oregonians who are in care homes or hospitals that prohibit aid in dying, it’s especially challenging for nonresidents.
When Oregon lifted its residency requirement, Blanke advertised on Craigslist and used the results to compile a list of short-term accommodations, including Airbnbs, willing to allow patients to die there. Nonprofits in states with aid-in-dying laws also maintain such lists, Sandeen said.
Milano hasn’t gotten to the point where she needs to find a place to take the meds and end her life. In fact, because she had a relatively healthy year after her first trip to Vermont, she let her six-month approval period lapse.
In June, though, she headed back to open another six-month window. This time, she went with a girlfriend who has a camper van. They drove six hours to cross the state border, stopping at a playground and gift shop before sitting in a parking lot where Milano had a Zoom appointment with her doctors rather than driving three more hours to Burlington to meet in person.
“I don’t know if they do GPS tracking or IP address kind of stuff, but I would have been afraid not to be honest,” she said.
That’s not all that scares her. She worries she’ll be too sick to return to Vermont when she is ready to die. And, even if she can get there, she wonders whether she’ll have the courage to take the medication. About one-third of people approved for assisted death don’t follow through, Blanke said. For them, it’s often enough to know they have the meds — the control — to end their lives when they want.
Milano said she is grateful she has that power now while she’s still healthy enough to travel and enjoy life. “I just wish more people had the option,” she said.

Coenzyme Q10 From Foods & Supplements
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.
Coenzyme Q10 and the difference it makes
Coenzyme Q10, often abbreviated to CoQ10, is a popular supplement, and is often one of the more expensive supplements that’s commonly found on supermarket shelves as opposed to having to go to more specialist stores or looking online.
What is it?
It’s a compound naturally made in the human body and stored in mitochondria. Now, everyone remembers the main job of mitochondria (producing energy), but they also protect cells from oxidative stress, among other things. In other words, aging.
Like many things, CoQ10 production slows as we age. So after a certain age, often around 45 but lifestyle factors can push it either way, it can start to make sense to supplement.
Does it work?
The short answer is “yes”, though we’ll do a quick breakdown of some main benefits, and studies for such, before moving on.
First, do bear in mind that CoQ10 comes in two main forms, ubiquinol and ubiquinone.
Ubiquinol is much more easily-used by the body, so that’s the one you want. Here be science:
What is it good for?
Benefits include:
- Against aging
- Against skin cancer
- Against breast cancer
- Against prostate cancer
- Against heart failure
- Against obesity
- Against diabetes
- Against Alzheimer’s
- Against Parkinson’s
Can we get it from foods?
Yes, and it’s equally well-absorbed through foods or supplementation, so feel free to go with whichever is more convenient for you.
Read: Intestinal absorption of coenzyme Q10 administered in a meal or as capsules to healthy subjects
If you do want to get it from food, you can get it from many places:
- Organ meats: the top source, though many don’t want to eat them, either because they don’t like them or some of us just don’t eat meat. If you do, though, top choices include the heart, liver, and kidneys.
- Fatty fish: sardines are up top, along with mackerel, herring, and trout
- Vegetables: leafy greens, and cruciferous vegetables e.g. cauliflower, broccoli, sprouts
- Legumes: for example soy, lentils, peanuts
- Nuts and seeds: pistachios come up top; sesame seeds are great too
- Fruit: strawberries come up top; oranges are great too
If supplementing, how much is good?
Most studies have used doses in the 100mg–200mg (per day) range.
However, it’s also been found to be safe at 1200mg (per day), for example in this high-quality study that found that higher doses resulted in greater benefit, in patients with early Parkinson’s Disease:
Effects of coenzyme Q10 in early Parkinson disease: evidence of slowing of the functional decline
Wondering where you can get it?
We don’t sell it (or anything else for that matter), and you can probably find it in your local supermarket or health food store. However, if you’d like to buy it online, here’s an example product on Amazon

Marathons in Mid- and Later-Life

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
We had several requests pertaining to veganism, meatless mondays, and substitutions in recipes—so we’re going to cover those on a different day!
As for questions we’re answering today…
Q: Is there any data on immediate and long term effects of running marathons in one’s forties?
An interesting and very specific question! We didn’t find an overabundance of studies specifically for the short- and long-term effects of marathon-running in one’s 40s, but we did find a couple of relevant ones:
The first looked at marathon-runners of various ages, and found that…
- there are virtually no relevant running time differences (p<0.01) per age in marathon finishers from 20 to 55 years
- the majority of middle-aged and elderly athletes have training histories of less than seven years of running
From which they concluded:
❝The present findings strengthen the concept that considers aging as a biological process that can be considerably speeded up or slowed down by multiple lifestyle related factors.❞
See the study: Performance, training and lifestyle parameters of marathon runners aged 20–80 years: results of the PACE-study
The other looked specifically at the impact of running on cartilage, controlled for age (45 and under vs 46 and older) and activity level (marathon-runners vs sedentary people).
The study had the people, of various ages and habitual activity levels, run for 30 minutes, and measured their knee cartilage thickness (using MRI) before and after running.
They found that regardless of age or habitual activity level, running compressed the cartilage tissue to a similar extent. From this, it can be concluded that neither age nor marathon-running result in long-term changes to cartilage response to running.
Or in lay terms: there’s no reason that marathon-running at 40 should ruin your knees (unless you are doing something wrong).
That may or may not have been a concern you have, but it’s what the study looked at, so hey, it’s information.
Here’s the study: Functional cartilage MRI T2 mapping: evaluating the effect of age and training on knee cartilage response to running
Q: Information on [e-word] dysfunction for those who have negative reactions to [the most common medications]?
When it comes to that particular issue, one or more of these three factors are often involved:
- Hormones
- Circulation
- Psychology
The most common drugs (that we can’t name here) work on the circulation side of things—specifically, by increasing the localized blood pressure. The exact mechanism of this drug action is interesting, albeit beyond the scope of a quick answer here today. On the other hand, the way that they work can cause adverse blood-pressure-related side effects for some people; perhaps you’re one of them.
To take matters into your own hands, so to speak, you can address each of those three things we just mentioned:
Hormones
Ask your doctor (or a reputable phlebotomy service) for a hormone test. If your free/serum testosterone levels are low (which becomes increasingly common in men over the age of 45), they may prescribe something—such as testosterone shots—specifically for that.
This way, it treats the underlying cause, rather than offering a workaround like those common pills whose names we can’t mention here.
Circulation
Look after your heart health; eat for your heart health, and exercise regularly!
Cold showers/baths also work wonders for vascular tone—which is precisely what you need in this matter. By rapidly changing temperatures (such as by turning off the hot water for the last couple of minutes of your shower, or by plunging into a cold bath), your blood vessels will get practice at constricting and maintaining that constriction as necessary.
Psychology
[E-word] dysfunction can also have a psychological basis. Unfortunately, this can also then be self-reinforcing, if recalling previous difficulties causes you to get distracted/insecure and lose the moment. One of the best things you can do to get out of this catch-22 situation is to not worry about it in the moment. Depending on what you and your partner(s) like to do in bed, there are plenty of other equally respectable options, so just switch track!
Having a conversation about this in advance will probably be helpful, so that everyone’s on the same page of the script in that eventuality, and it becomes “no big deal”. Without that conversation, misunderstandings and insecurities could arise for your partner(s) as well as yourself (“aren’t I desirable enough?” etc).
So, to recap, we recommend:
- Have your hormones checked
- Look after your circulation
- Make the decision to have fun!
