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

Exercise can't counteract the damage being done to your body while you continue to smoke. What exercise can do is help you kick the habit.

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

Aerobic dancing is already adjusting to injury problems and will probably phase out to some extent.

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 used to think that it didn't make any difference how far you ran if you had a good, strong musculoskeletal system and no underlying cardiovascular problems.

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