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.

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

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.

If you look at body fat, it seems to increase with age, even though your weight does not. That's a physiological fact of aging, they say. Heck it is. It is an adaptive effect of aging.
