"WHY ARE YOU here?" the tech asked me when I went in for my cardiac stress test. It was a reasonable question. I'd walked in with normal body weight, low-normal blood pressure, and a resting heart rate of 48. So why did I need a cardiac stress test?

The answer was that I was recovering from a central retinal vein occlusion--a stroke, but in my eye. It was probably brought on by stress, my doctors said, because I had none of the risk factors for cardiovascular trouble. Non-smoking (except for the occasional cigar) trail runners who watch what they eat and maintain a healthy weight over decades aren't supposed to be likely candidates for dislodged blood clots.

As the months passed and the tests turned up few follow-on problems, it became apparent that my poor candidacy for an eye stroke made me a good candidate for a strong recovery. "Keep exercising," the medical types told me. "It seems to be working for you."

It's good sense when you think about it. Libertarians are rightly quick to complain about intrusions into our autonomy--rules, regulations, and directives that compromise our ability to run our own lives. But nothing limits your independence like an inability to walk down the street under your own power.

Continuous maintenance on anything lowers the chance that you'll have to do serious repairs. Change the oil in the car, swap out the filters on the HVAC system, and do some damned crunches, and you'll reduce the likelihood of the kind of big hassle--and the related bills--that come from neglect. Maintenance is also something most of us can do ourselves. It's the major repairs, on our bodies in particular, that make us dependent on the skills and availability of experts and their technology.

"Regular exercise helps prevent or manage a wide range of health problems and concerns, including stroke, metabolic syndrome, type 2 diabetes, depression, a number of types of cancer, arthritis and falls," the Mayo Clinic advises on its website. That stroke in the list jumps out at me given my personal experience, and given the recent reversal of a decadeslong decline in the rate of deaths from strokes. (The Centers for Disease Control and Prevention says 32,593 more stroke deaths occurred in 2013-2015 than would have if earlier trends had continued.) But diabetes is another condition on the rise, increasing its reach in recent years to between 12 and 14 percent of adult...
