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

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

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.

The reason I exercise is for the quality of life I enjoy.

You have to run 75 to 100 miles a week if you expect to break the four-minute mile.

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

We are involved in youth testing internationally. We want to try to prove without a shadow of a doubt the relationship between physical fitness and health, not just physical fitness and ability to perform.
