Over the years, Ive covered 22,000 miles.

Since then, I have not missed five consecutive days in getting some type of aerobic exercise, mostly jogging.

If you look at body fat, it seems to increase with age, even though your weight does not. That's a physiological fact of aging, they say. Heck it is. It is an adaptive effect of aging.

So I've broadened the fitness concept to make it one of moderation and balance.

Over the years, Ive covered 22,000 miles.

According to the Gallup Poll, 24 percent of American adults exercised regularly in 1961, and 50 percent after 1968. The peak was 59 percent in 1984, dropping off to 51 percent last September.

I think investments in general related to the exercise industry are going to be good for a long time.
