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.

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

There are six components of wellness: proper weight and diet, proper exercise, breaking the smoking habit, control of alcohol, stress management and periodic exams.

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.

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.

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

Over the years, Ive covered 22,000 miles.
