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.

I have not missed a day from work because of illness since 1956.

Over the years, Ive covered 22,000 miles.

I don't criticize weight training - as long as it is not a substitute for aerobic training.

You have to run 75 to 100 miles a week if you expect to break the four-minute mile.

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

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.
