No one would doubt that. Q is whether there might still be a
deleterious effect on aging. I think there almost certainly is. If you
looked at people who exercise regularly and vigorously all their
lives, you'd prob'ly see far fewer deaths compared w/normals until the
age of 75 or 80, and then you'd see more. Aging ~= use of energy, so
no surprise there.

If you're at risk for heart disease, and you can't control the risk
through diet, then regularly aerobic exercise is wise. Otherwise, just
a little load-bearing exercise is all that's needed, from a health
standpoint. (Other standpoints exist, tho', to be sure.)

Check out the fascinating reseasrch of JOhn Holloszy for more on
these questions.
