Why This Video Is Important
A lot of what we talk about here at 10almonds is focused on healthy aging. We want you – our lovely readers – to not only live for a long time, but also be healthy enough to enjoy that “long time”.
We’ve talked about anything from Dr. Greger’s eight anti-aging interventions, to the specific benefits of resveratrol or metformin in combatting aging, to even reducing stress-induced aging.
So, why is this video important? It goes beyond just talking about what we know about living longer, but also focuses on how we should live longer; there’s a big difference between living a long life but never leaving your house vs. living a long life beyond your front door.
The Takeaways
The core message that Big Think wants to convey is that our lifestyle is our best bet in slowing the aging process. Our bodies are adaptive systems, responding positively to healthy lifestyle choices. They focus on exercise: regular physical activity increases healthspan, consequently extending lifespan.
A key takeaway is the difference between physical activity and exercise. While any movement counts as physical activity, exercise is a deliberate, health-focused activity. It benefits the brain by releasing growth factors that strengthen critical areas like the hippocampus and prefrontal cortex.
The video encourages embracing physical activity in any form available to you, from gardening to walking. The goal isn’t to hit a specific number of steps but to stay active in a way that suits your lifestyle.
Science may not solve death. Yet. But focusing on maintaining a healthy, functioning state for as long as possible is the real victory in the battle against aging. And, at the moment, exercise seems to be our best bet:

Kidney Beans vs Pinto Beans – 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 kidney beans to pinto beans, we picked the pinto.
Why?
Looking at the macros first, pinto beans have slightly more protein and carbs, and a lot more fiber, making them the all-round “more food per food” choice.
In the vitamins category, kidney beans have more of vitamins B3, C, and K, while pinto beans have more of vitamins B1, B2, B6, B9, E, and choline; another win for pinto beans. In kidney beans’ defense though, with the exception of vitamin E (31x more in pinto beans) the margins of difference are small for the rest of these vitamins, making kidney beans a close runner-up. Still, at least a nominal win for pinto beans here, by the numbers.
When it comes to minerals, kidney beans are not higher in any minerals, while pinto beans have more calcium, copper, magnesium, manganese, phosphorus, potassium, and selenium. In kidney beans’ defense, though, with the exception of selenium (5–6x more in pinto beans) the margins of difference are small for the rest of these minerals, making kidney beans a fine choice here too. Once again though, a winner is declarable here by the numbers, and it’s pinto beans.
Adding up the three wins makes for one big win for pinto beans. Still, enjoy either or both, because kidney beans are great too, and so is diversity!

It’s Q&A Time!
This is the bit whereby each week, we respond to subscriber questions/requests/etc
Have something you’d like to ask us, or ask us to look into? Hit reply to any of our emails, or use the feedback widget at the bottom, and a Real Human™ will be glad to read it!
Q: As to specific health topics, I would love to see someone address all these Instagram ads targeted to women that claim “You only need to ‘balance your hormones’ to lose weight, get ripped, etc.” What does this mean? Which hormones are they all talking about? They all seem to be selling a workout program and/or supplements or something similar, as they are ads, after all. Is there any science behind this stuff or is it mostly hot air, as I suspect?
Thank you for asking this, as your question prompted yesterday’s main feature, What Does “Balancing Your Hormones” Even Mean?
That’s a great suggestion also about addressing ads (and goes for health-related things in general, not just hormonal stuff) and examining their claims, what they mean, how they work (if they work!), and what’s “technically true but may
be misleading* cause confusion”*We don’t want companies to sue us, of course.
Only, we’re going to need your help for this one, subscribers!
See, here at 10almonds we practice what we preach. We limit screen time, we focus on our work when working, and simply put, we don’t see as many ads as our thousands of subscribers do. Also, ads tend to be targeted to the individual, and often vary from country to country, so chances are good that we’re not seeing the same ads that you’re seeing.
So, how about we pull together as a bit of a 10almonds community project?
- Step 1: add our email address to your contacts list, if you haven’t already
- Step 2: When you see an ad you’re curious about, select “share” (there is usually an option to share ads, but if not, feel free to screenshot or such)
- Step 3: Send the ad to us by email
We’ll do the rest! Whenever we have enough ads to review, we’ll do a special on the topic.
We will categorically not be able to do this without you, so please do join in—Many thanks in advance!

Do CBD Gummies Work?

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
❝I take CBD gummies. I don’t know if they are worth buying. Can you find a study on the effectiveness of gummies❞
If you take them, and you’re not sure whether they’re worth it, then it sounds like you’re not getting any observable benefit from them?
If so, that would seem to answer your question, since presumably the reason that you are taking them is for relaxation and/or pain relief, so if you’re not getting the results you want, then no, they are not worth it.
However! CBD gummies are an incredibly diverse and not-well-studied product, so far, given the relative novelty of their legality. By diverse we mean, they’re not well-standardized.
In other words: the CBD gummies you get could be completely unlike CBD gummies from a different source.
CBD itself (i.e. in forms other than just gummies, and mostly as oil) has been studied somewhat better, and we did a main feature on it here:
And while we’re at it:
Cannabis Myths vs Reality ← This one is about cannabis products in general, and includes discussion of THC content and effects, which might not be so relevant to you, but may to some readers.
Companies selling CBD and CBD gummies may make bold claims that are not yet backed by science, so if you are buying them for those reasons, you might want to be aware:

One thing that we would add is that even though CBD is generally recognized as safe, it is possible to overdose on CBD gummies, so do watch your limits:

Is Dairy Scary?
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.
Is Dairy Scary?
Milk and milk products are popularly enjoyed as a good source of calcium and vitamin D.
In contrast, critics of dairy products (for medical reasons, rather than ethical, which is another matter entirely and beyond the scope of this article) point to risks of cancer, heart disease, and—counterintuitively—osteoporosis. We’ll focus more on the former, but touch on the latter two before closing.
Dairy & Cancer
Evidence is highly conflicting. There are so many studies with so many different results. This is partially explicable by noting that not only is cancer a many-headed beast that comes in more than a hundred different forms and all or any of them may be affected one way or another by a given dietary element, but also… Not all milk is created equal, either!
Joanna Lampe, of the Public Health Sciences division, Fred Hutchinson Cancer Research Center in Seattle, writes:
❝Dairy products are a complex group of foods and composition varies by region, which makes evaluation of their association with disease risk difficult. For most cancers, associations between cancer risk and intake of milk and dairy products have been examined only in a small number of cohort studies, and data are inconsistent or lacking❞
In her systematic review of studies, she noted, for example, that:
- Milk and dairy products contain micronutrients and several bioactive constituents that may influence cancer risk and progression
- There’s probable association between milk intake and lower risk of colorectal cancer
- There’s a probable association between diets high in calcium and increased risk of prostate cancer
- Some studies show an inverse association between intake of cultured dairy products and bladder cancer (i.e., if you eat yogurt you’re less likely to get bladder cancer)
Since that systemic review was undertaken, more research has been conducted, and the results are… Not conclusive, but converging towards a conclusion:
- Dairy products can increase or decrease cancer risk
- The increase in cancer risk seems strongest when milk is consumed in quantities that result in too much calcium. When it comes to calcium, you can absolutely have too much of a good thing—just ask your arteries!
- The decrease in cancer seems to be mostly, if not exclusively, from fermented dairy products. This usually means yogurts. The benefit here is not from the milk itself, but rather from the gut-friendly bacteria.
You may be wondering: “Hardened arteries, gut microbiome health? I thought we were talking about cancer?” and yes we are. No part of your health is an island unrelated to other parts of your health. One thing can lead to another. Sometimes we know how and why, sometimes we don’t, but it’s best to not ignore the data.
The bottom line on dairy products and cancer is:
- Consuming dairy products in general is probably fine
- Yogurt, specifically, is probably beneficial
Dairy and Heart Disease
The reason for the concern is clear enough: it’s largely assumed to be a matter of saturated fat intake.
The best combination of “large” and “recent” that we found was a three-cohort longitudinal study in 2019, which pretty much confirms what was found in smaller or less recent studies:
- There is some evidence to suggest that consumption of dairy can increase all-cause mortality in general, and death from (cancer and) cardiovascular disease in particular
- The evidence is not, however, overwhelming. It is marginal.
Dairy and Osteoporosis
Does dairy cause osteoporosis? Research here tends to fall into one of two categories when it comes to conclusions, so we’ll give an example of each:
- “Results are conflicting, saying yes/no/maybe, and basically we just don’t know”
- “Results are conflicting, but look: cross-sectional and case-control studies say yes; cohort studies say maybe or no; we prefer the cohort studies”
See them for yourself:
- Osteoporosis: Is milk a kindness or a curse?
- Consumption of milk and dairy products and risk of osteoporosis and hip fracture
Conclusion: really, the jury is very much still out on this one
Summary:
- Moderate consumption of dairy products is almost certainly fine
- More specifically: it probably has some (small) pros and some (small) cons
- Yogurt is almost certainly healthier than other dairy products, and is almost universally considered a healthy food (assuming not being full of added sugar etc, of course)
- If you’re going to have non-dairy alternatives to milk, choose wisely!
That’s all we have time for today, but perhaps in a future edition we’ll do a run-down of the pros and cons of various dairy alternatives!

Driving under the influence of marijuana: An explainer and research roundup
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.
Update 1: On May 16, 2024, the U.S. Department of Justice sent a proposed rule to the Federal Register to downgrade marijuana from a Schedule I to a Schedule III drug. This is the first step in a lengthy approval process that starts with a 60-day comment period.
Update 2: Two recent research studies were added to the “Studies on marijuana and driving” section of this piece on July 18, 2024.
As marijuana use continues to rise and state-level marijuana legalization sweeps the U.S., researchers and policymakers are grappling with a growing public safety concern: marijuana-impaired driving.
As of April 2023, 38 U.S. states had legalized medical marijuana and 23 had legalized its recreational use, according to the National Conference of State Legislatures. Recreational or medical marijuana measures are on the ballot in seven states this year.
The issue of marijuana-impaired driving has not been an easy one to tackle because, unlike alcohol, which has well-established thresholds of impairment, the metrics for marijuana’s effects on driving remain rather elusive.
“We don’t have that kind of deep knowledge right now and it’s not because of lack of trying,” says Dr. Guohua Li, professor of epidemiology and the founding director of the Center for Injury Science and Prevention at Columbia University.
“Marijuana is very different from alcohol in important ways,” says Li, who has published several studies on marijuana and driving. “And one of them is that the effect of marijuana on cognitive functions and behaviors is much more unpredictable than alcohol. In general, alcohol is a depressant drug. But marijuana could act on the central nervous system as a depressant, a stimulant, and a hallucinogenic substance.”
Efforts to create a breathalyzer to measure the level of THC, the main psychoactive compound found in the marijuana plant, have largely failed, because “the THC molecule is much bigger than ethanol and its behavior after ingestion is very different from alcohol,” Li says.
Currently, the two most common methods used to measure THC concentration to identify impaired drivers are blood and saliva tests, although there’s ongoing debate about their reliability.
Marijuana, a term interchangeably used with cannabis, is the most commonly used federally illegal drug in the U.S.: 48.2 million people, or about 18% of Americans reported using it at least once in 2019, according to the latest available data from the Centers for Disease Control and Prevention. Worldwide, 2.5% of the population consumes marijuana, according to the World Health Organization.
Marijuana is legal in several countries, including Canada, where it was legalized in 2018. Despite state laws legalizing cannabis, it remains illegal at the federal level in the U.S.
As states grapple with the contentious issue of marijuana legalization, the debate is not just about public health, potential tax revenues and economic interests. At the heart of the discussion is also the U.S. criminal justice system.
Marijuana is shown to have medicinal qualities and, compared with substances like alcohol, tobacco, and opioids, it has relatively milder health risks. However, it’s not risk-free, a large body of research has shown.
Marijuana consumption can lead to immediate effects such as impaired muscle coordination and paranoia, as well as longer-term effects on mental health and cognitive functions — and addiction. As its use becomes more widespread, researchers are trying to better understand the potential hazards of marijuana, particularly for younger users whose brains are in critical stages of development.
Marijuana and driving
The use of marijuana among drivers, passengers and pedestrians has increased steadily over the past two decades, Li says.
Compared with the year 2000, the proportion of U.S. drivers on the road who are under the influence of marijuana has increased by several folds, between five to 10 times, based on toxicology testing of people who died in car crashes, Li says.
A 2022 report from the National Transportation Safety Board finds alcohol and cannabis are the two most commonly detected drugs among drivers arrested for impaired driving and fatally injured drivers. Most drivers who tested positive for cannabis also tested positive for another potentially impairing drug.
“Although cannabis and many other drugs have been shown to impair driving performance and are associated with increased crash risk, there is evidence that, relative to alcohol, awareness about the potential dangers of driving after using other drugs is lower,” according to the report.
Indeed, many U.S. adults perceive daily marijuana use or exposure to its smoke safer than tobacco, even though research finds otherwise.
Several studies have demonstrated marijuana’s impact on driving.
Marijuana use can reduce the drivers’ ability to pay attention, particularly when they are performing multiple tasks, research finds. It also slows reaction time and can impair coordination.
“The combination is that you potentially have people who are noticing hazards later, braking slower and potentially not even noticing hazards because of their inability to focus on competing things on the road,” says Dr. Daniel Myran, an assistant professor at the Department of Family Medicine and health services researcher at the University of Ottawa.
In a study published in September in JAMA Network Open, Myran and colleagues find that from 2010 to 2021 the rate of cannabis-involved traffic injuries that led to emergency department visits in Ontario, Canada, increased by 475%, from 0.18 per 1,000 traffic injury emergency department visits in 2010 to 1.01 visits in 2021.
To be sure, cannabis-involved traffic injuries made up a small fraction of all traffic injury-related visits to hospital emergency departments. Out of 947,604 traffic injury emergency department visits, 426 had documented cannabis involvement.
Myran cautions the increase shouldn’t be solely attributed to marijuana legalization. It captures changing societal attitudes toward marijuana and acceptance of cannabis use over time in the lead-up to legalization. In addition, it may reflect an increasing awareness among health care providers about cannabis-impaired driving, and they may be more likely to ask about cannabis use and document it in medical charts, he says.
“When you look at the 475% increase in cannabis involvement in traffic injuries, rather than saying legalizing cannabis has caused the roads to be unsafe and is a public health disaster, it’s that cannabis use appears to be growing as a risk for road traffic injuries and that there seem to be more cannabis impaired drivers on the road,” Myran says. “Legalization may have accelerated this trend. Faced with this increase, we need to think about what are public health measures and different policy interventions to reduce harms from cannabis-impaired driving.”
Setting a legal limit for marijuana-impaired driving
Setting a legal limit for marijuana-impaired driving has not been easy. Countries like Canada and some U.S. states have agreed upon a certain level of THC in blood, usually between 1 to 5 nanograms per milliliter. Still, some studies have found those limits to be weak indicators of cannabis-impaired driving.
When Canada legalized recreational marijuana in 2018, it also passed a law that made it illegal to drive with blood THC levels of more than 2 nanograms. The penalties are more severe for blood THC levels above 5 nanograms. The blood test is done at the police station for people who are pulled over and are deemed to be drug impaired.
In the U.S., five states — Ohio, Illinois, Montana, Washington and Nevada — have “per se laws,” which set a specific amount of THC in the driver’s blood as evidence of impaired driving, according to the National Conference of State Legislatures. That limit ranges between 2 and 5 nanograms of THC per milliliter of blood.
Colorado, meanwhile, has a “permissible inference law,” which states that it’s permissible to assume the driver was under the influence if their blood THC level is 5 nanograms per milliliter or higher, according to NCSL.
Twelve states, most which have legalized some form of marijuana of use, have zero tolerance laws for any amount of certain drugs, including THC, in the body.
The remaining states have “driving under the influence of drugs” laws. Among those states, Alabama and Michigan, have oral fluid roadside testing program to screen drivers for marijuana and other drugs, according to NCSL.
In May this year, the U.S. Department of Transportation published a final rule that allows employers to use saliva testing for commercially licensed drivers, including truck drivers. The rule, which went into effect in June, sets the THC limit in saliva at 4 nanograms.
Saliva tests can detect THC for 8 to 24 hours after use, but the tests are not perfect and can results in false positives, leading some scientists to argue against using them in randomly-selected drivers.
In a 2021 report, the U.S. National Institute of Justice, the research and development arm of the Department of Justice, concluded that THC levels in bodily fluids, including blood and saliva “were not reliable indicators of marijuana intoxication.”
Studies on marijuana and driving
Over the past two decades, many studies have shown marijuana use can impair driving. However, discussions about what’s the best way to measure the level of THC in blood or saliva are ongoing. Below, we highlight and summarize several recent studies that address the issue. The studies are listed in order of publication date. We also include a list of related studies and resources to inform your audiences.
State Driving Under the Influence of Drugs Laws
Alexandra N. Origenes, Sarah A. White, Emma E. McGinty and Jon S. Vernick. Journal of Law, Medicine & Ethics, July 2024.Summary: As of January 2023, 33 states and D.C. had a driving under the influence of drugs law for at least one drug other than cannabis. Of those, 29 states and D.C. had a law specifically for driving under the influence of cannabis, in addition to a law for driving under the influence of other drugs. Four states had a driving under the influence of drug laws, excluding cannabis. Meanwhile, 17 states had no law for driving under the influence of drugs, including cannabis. “The 17 states lacking a DUID law that names specific drugs should consider enacting such a law. These states already have expressed their concern — through legislation — with drug-impaired driving. However, failure to name specific drugs is likely to make the laws more difficult to enforce. These laws may force courts and/or law enforcement to rely on potentially subjective indicators of impairment,” the authors write.
Associations between Adolescent Marijuana Use, Driving After Marijuana Use and Recreational Retail Sale in Colorado, USA
Lucas M. Neuroth, et al. Substance Use & Misuse, October 2023.Summary: Researchers use data from four waves (2013, 2015, 2017 and 2019) of the Healthy Kids Colorado Survey, including 47,518 students 15 and older who indicated that they drove. They find 20.3% of students said that they had used marijuana in the past month and 10.5% said they had driven under the influence of marijuana. They find that the availability of recreational marijuana in stores was associated with an increased prevalence of using marijuana one to two times in the past month and driving under the influence of marijuana at least once. “Over the study period, one in ten high school age drivers engaged in [driving after marijuana use], which is concerning given the high risk of motor vehicle-related injury and death arising from impaired driving among adolescents,” the authors write.
Are Blood and Oral Fluid Δ9-tetrahydrocannabinol (THC) and Metabolite Concentrations Related to Impairment? A Meta-Regression Analysis
Danielle McCartney, et al. Neuroscience & Biobehavioral Reviews, March 2022.Summary: Commonly used THC measurements may not be strong indicators of driving impairment. While there is a relationship between certain biomarkers like blood THC concentrations and impaired driving, this correlation is often weak. The study underscores the need for more nuanced and comprehensive research on this topic, especially as cannabis usage becomes more widespread and legally accepted.
The Effects of Cannabis and Alcohol on Driving Performance and Driver Behaviour: A Systematic Review and Meta-Analysis
Sarah M. Simmons, Jeff K. Caird, Frances Sterzer and Mark Asbridge. Addiction, January 2022.Summary: This meta-analysis of experimental driving studies, including driving simulations, confirms that cannabis impairs driving performance, contrary to some beliefs that it might enhance driving abilities. Cannabis affects lateral control and speed — typically increasing lane excursions while reducing speed. The combination of alcohol and marijuana appears worse than either alone, challenging the idea that they cancel each other out.
Cannabis Legalization and Detection of Tetrahydrocannabinol in Injured Drivers
Jeffrey R. Brubacher, et al. The New England Journal of Medicine, January 2022.Summary: Following the legalization of recreational marijuana in Canada, there was a notable increase in injured drivers testing positive for THC, especially among those 50 years of age or older. This rise in cannabis-related driving incidents occurred even with new traffic laws aiming to deter cannabis-impaired driving. This uptick began before legalization became official, possibly due to perceptions that cannabis use was soon-to-be legal or illegal but not enforced. The data suggests that while legalization has broad societal impacts, more comprehensive strategies are needed to deter driving under the influence of cannabis and raise public awareness about its risks.
Cannabis and Driving
Godfrey D. Pearlson, Michael C. Stevens and Deepak Cyril D’Souza. Frontiers in Psychiatry, September 2021.Summary: Cannabis-impaired driving is a growing public health concern, and studies show that such drivers are more likely to be involved in car crashes, according to this review paper. Drivers are less affected by cannabis than they are by alcohol or cocaine, but the problem is expected to escalate with increasing cannabis legalization and use. Unlike alcohol, THC’s properties make it challenging to determine direct impairment levels from testing results. Current roadside tests lack precision in detecting genuine cannabis-impaired drivers, leading to potential wrongful convictions. Moreover, there is a pressing need for research on the combined effects of alcohol and cannabis on driving, as well as the impact of emerging popular forms of cannabis, like concentrates and edibles. The authors recommend public awareness campaigns about the dangers of driving under the influence of cannabis, similar to those against drunk driving, to address misconceptions. Policymakers should prioritize science-based decisions and encourage further research in this domain.
Demographic And Policy-Based Differences in Behaviors And Attitudes Towards Driving After Marijuana Use: An Analysis of the 2013–2017 Traffic Safety Culture Index
Marco H. Benedetti, et al. BMC Research Notes, June 2021.Summary: The study, based on a U.S. survey, finds younger, low-income, low-education and male participants were more tolerant of driving after marijuana consumption. Notably, those in states that legalized medical marijuana reported driving after use more frequently, aligning with studies indicating a higher prevalence of THC detection in drivers from these states. Overall, while the majority perceive driving after marijuana use as dangerous, not all research agrees on its impairment effects. Existing studies highlight that marijuana impacts motor skills and executive functions, yet its direct correlation with crash risk remains debated, given the variations in individual tolerance and how long THC remains in the system.
Driving Under the Influence of Cannabis: A Framework for Future Policy
Robert M. Chow, et al.Anesthesia & Analgesia, June 2019.Summary: The study presents a conceptual framework focusing on four main domains: legalization, driving under the influence of cannabis, driver impairment, and motor vehicle accidents. With the growing legalization of cannabis, there’s an anticipated rise in cannabis-impaired driving cases. The authors group marijuana users into infrequent users who show significant impairment with increased THC blood levels, chronic users with minimal impairment despite high THC levels, and those with consistent psychomotor deficits. Current challenges lie in the lack of standardized regulation for drivers influenced by cannabis, primarily because of state-to-state variability and the absence of a federal statutory limit for blood THC levels. European nations, however, have established thresholds for blood THC levels, ranging from 0.5 to 50.0 micrograms per liter depending on whether blood or blood serum are tested. The authors suggest the combined use of alcohol and THC blood tests with a psychomotor evaluation by a trained professional to determine impairment levels. The paper stresses the importance of creating a structured policy framework, given the rising acceptance and use of marijuana in society.

The humble bodyweight squat is shown to contribute to everything from bolstering all-around lower body strength to bettering bone density and increasing metabolism.
Indeed, squats are so powerful that we reviewed a whole book that focuses just on the topic of squatting. Other, broader books on exercise also focus on the positive impacts that squatting can make.
A proper squat goes beyond your legs, engaging your core, enhancing joint health, and, some argue, can lead to improved balance and circulation.
(Plus, they’re easy to execute, given they can be done anywhere, without any equipment).
This is probably why Luigi Fontana and Dr Rangan Chatterjee have spoken about the benefits of squatting.
How Should We Start?
The video goes beyond the ‘why’ and delves into the ‘how’, offering step-by-step squatting techniques.
It answers the burning question: should you really be doing squats every day?
(Hint: the answer is most likely “yes”).
Of course, some of us may not be able to squat, and for those, we’ll feature alternatives in a future article.
For beginners, the advice is to start slow, aiming for 10 repetitions. You can gradually increase that count as you feel your muscles strengthen. Experienced gym-goers might push for 20 or more reps, adding variations like jump squats for an extra challenge.
The key takeaway is to listen to your body and ensure rest days for muscle recovery.
At the end of the day, Passion for Health’s video is a treasure trove for squat lovers, from novices to the seasoned, and insists on the importance of form, frequency, and listening to one’s body.
