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.

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

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.

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.

Aerobic dancing is already adjusting to injury problems and will probably phase out to some extent.

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

Over the years, Ive covered 22,000 miles.
