Now I say that if you run more than 15 miles a week, it's for something other than aerobic fitness. Once you pass 15 miles, you do not see much further improvement.

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

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

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.

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

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

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