As I wait for an Aleve pill to kick-in to take the pain out of a bad knee with very little meniscus, I read this article from AARP about how baby-boomers can help stay healthy. The answer is exercise. The rewards to doing it can be many, it says. Here's one description of this just before super-wife and I go for a walk:
"Exercise seems to be one of the key factors that distinguish people who have a healthy old age from those who don't," says Suzanne Leveille, a professor of nursing at the University of Massachusetts Boston who is conducting research on disability in older people.
"Being sedentary is a known risk factor for just about every poor health outcome, from being hospitalized to ending up in a nursing home, and even to mortality."
