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

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.

Far too many times over the next 12 to 15 years, it was brought to my attention that people who followed my exercise guidelines exactly but ignored their diet, their weight and their cigarette smoking had heart attacks at age 55.

It's easier and more cost effective to maintain good health, than to regain it once it's lost.

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

After 26 years, I am still practicing what I preach.

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