Happily, except for playgrounds, outdoor public spaces are still open where I live.

The outdoors and sunshine are such strong factors in fighting viral infections that a 2009 study of the extraordinary success of outdoor hospitals during the 1918 influenza epidemic suggested that during the next pandemic (I guess this one!) we should encourage “the public to spend as much time outdoors as possible,” as a public-health measure.

Always true, just now laid bare by the pandemic:

In transit conversations we often talk about meeting the needs of people who depend on transit. This makes transit sound like something we’re doing for them. But in fact, those people are providing services that we all depend on, so by serving those lower income riders, we’re all serving ourselves.

Probably just another instance of “people who drink moderately have other healthy behaviors as well,” but very much in keeping with my preconceptions:

Compared with abstainers, those who drank one to 13 standard drinks a week had a 66 percent lower rate of beta amyloid deposits in their brains.

I find it super easy to spend time outdoors in the summer. Anytime the weather is nice, I’ll almost automatically get out for at least a couple of hours per day. I’m a lot less motivated to do so when it’s cold or wet. This post is largely here to help me remember how nice it is to get outside, even when the weather isn’t so pleasant.

How nice is it? Really, really nice. And yet, I forget, so I end up having to manipulate myself into getting outside in the winter.

I find it easy to manipulate myself with perceived health benefits, such as the well-documented benefits of spending time in nature. I’d find the self-manipulation thing even easier if we knew a bit more about what the “active ingredients” are with regard to time in nature.

Maybe it’s visual. Does the appearance of leaves and trees have some effect on the brain? (I have my own theory that dappled shade has soothing effects on the brain due to our evolution as forest-edge animals.)

Maybe it’s chemical. Trees release all sorts of chemicals into the air, as do bacteria and fungi that live in the soil. I imagine that these are reduced during the winter when the trees are dormant and the soil is covered with snow, but I don’t know of any relevant data.

Besides health benefits, the main ways I motivate myself is either by finding a way to perceive the activity as enjoyable (as being outside on a nice summer day) or else to find a way to smugly perceive the activity as so unpleasant that lesser beings could not bestir themselves to get out in such wretched weather. (One of my mottos: If the weather can’t be good, it should at least be bad enough to be interesting.)

One practical idea I used today: In winter the sunrise is late enough to not have to get up early to get see it. Take advantage of that. See the dawn. Watch the sun rise. Then go back inside where it’s warm.

About 12 minutes before sunrise

Since reading a couple of weeks ago about the importance of blue places for both physical and mental health, I’ve been trying to spend a little more time near water, and to pay attention when I’m there.

Today Jackie and I took a short walk along the little creek that runs just south of Winfield Village. It’s really a spectacular amenity that I don’t appreciate nearly as much as I should. (I spend a lot of time admiring our little prairie and our little woods, but I mostly just cross the creek itself with scant notice—nowhere near what it deserves.)

Perhaps you can help me catch up on appreciating our creek. Is it not admirable?

It got me some vitamin W for the water and some vitamin N for the nature, but sadly no vitamin D. The vitamin D window has closed, and won’t open again for 57 days.

I have spent a lot of time following the latest research on all sorts of interventions to increase lifespan and healthspan. I am now ready to say that virtually all this time has been wasted.

I guess it hasn’t technically been wasted, in that I’ve come to understand the latest research, and that’s of some value. But when it comes to choosing interventions that might help me, it turns out there’s nothing new beyond the obvious healthy lifestyle recommendations of 20 or even 30 years ago.

There are a bunch of chemical interventions that are interesting—they have definitely been shown to increase healthspan and lifespan in animal models, and have had some very promising results in humans as well. However, it is becoming clear that virtually all of them are either exercise mimetics or fasting mimetics—drugs that activate (some of) the metabolic pathways activated by exercise or fasting.

From a public health perspective, perhaps this is of some interest. Given a population of sedentary people with poor diets it’s easy to foresee a mix of these drugs delaying mortality and morbidity—people will live longer, and during their extended lifespan they’ll have less disability, less illness, and require less medical care.

From my perspective though, it’s completely uninteresting. I would much rather just exercise than take a drug that provides a subset of the benefits of exercise. Similarly, I’d much rather just eat good food than take a drug that simulates some of the effects of doing so.

Do you want to live a long, healthy life? Here’s an plan for you:

  1. Eat a whole-food diet that’s low in sugar and refined carbs. Try to include a couple servings of salmon (or other fatty fish) per week.
  2. Finish supper at least 3 hours before bedtime, and make sure there’s at least 12 (preferably 13 or 14) hours between the end of supper and the start of breakfast.
  3. Get at least 2 resistance workouts a week where you exercise your big muscles (glutes, quads, hamstrings, pecs, traps, lats) until they are briefly very tired.
  4. Get at least 2 endurance workouts a week where you spend an hour or so exercising at a pace that’s a little more intense than a brisk walk.
  5. Get 1 workout a week where you raise your heart rate to 80% of its maximum for 30 seconds, rest for 30 seconds, and then repeat for a total of 10 rounds.
  6. Spend some time outdoors at least several times a week.
  7. Sleep until you wake up naturally almost every night.

That’s it. Unless you are sick with a diagnosed condition for which there is treatment, I very much doubt there is anything modern medicine—or even bleeding-edge longevity research—can do for you that you won’t get from this plan.

I’m sure my brother is very amused that it has taken me this long to come to this conclusion.
