Over the years, I've covered 22,000 miles.
After 26 years, I am still practicing what I preach.
The reason I exercise is for the quality of life I enjoy.
I have not missed a day from work because of illness since 1956.
So I've broadened the fitness concept to make it one of moderation and balance.
You have to run 75 to 100 miles a week if you expect to break the four-minute mile.
I don't criticize weight training - as long as it is not a substitute for aerobic training.
Aerobic dancing is already adjusting to injury problems and will probably phase out to some extent.
I think investments in general related to the exercise industry are going to be good for a long time.
Since then, I have not missed five consecutive days in getting some type of aerobic exercise, mostly jogging.
