Performance at Various Ages

I’ve long thought about how one’s performance, both mental and physical, changes with age. The common narrative is that it simply deteriorates, but I think that’s a bit simplistic. We all know, or at least know of, people in their 60s who run mental and physical circles around people in their 20s. A simple map […]

How Exercise Calms Anxiety

So they gathered adult mice, injected them with a substance that marks newborn cells in the brain, and for six weeks, allowed half of them to run at will on little wheels, while the others sat quietly in their cages.Afterward, the scientists determined each group’s baseline nervousness. Given access to cages with open, well-lighted areas, […]

Rowing Gamified

Gamification of exercise is not something I’d normally endorse, since the effect is likely to be extremely temporary. But in the case of indoor rowing on an ergometer I think it’s much different. I am not in any kind of shape whatsoever, and I did 500M in 2:00 this morning. I was on a WAY […]

Existential Depression in Gifted Individuals

Yalom 1980 describes four such issues or "ultimate concerns"–death, freedom, isolation and meaninglessness. Death is an inevitable occurrence.

What doctors should probably add is that the health of unborn children can be affected by what and how much men eat; the toxins they absorb; the traumas they endure; their poverty or powerlessness; and […]

Perhaps the Most Important Health Article Anyone Can Read in 3 Minutes

New York Times bestselling author Gretchen Reynolds wrote a whole book about the subject matter called The First 20 Minutes. To get the highest level of happiness and benefits for health, the key is not to become a professional athlete. On the contrary, a much smaller amount is needed to reach the level where happiness […]

Persistent Cannabis Users Show Neuropsychological Decline

Persistent cannabis use was associated with neuropsychological decline broadly across domains of functioning, even after controlling for years of education. Informants also reported noticing more cognitive problems for persistent cannabis users. Impairment was concentrated among adolescent-onset cannabis users, with more persistent use associated with greater decline. Further, cessation of cannabis use did not fully restore […]

The Real Reason to Exercise

Most seem to think you should exercise to avoid dying early. That’s an acceptable reason, I suppose, but it misses what I believe to be much more important. Exercise enables you to function the way you should function. It’s a magnifier of value. It helps you finish writing that book, to travel the world, and […]
