The latest, most startling evidence from ACLs – fit people are showing lower risks for senile dementia and even Alzheimers.  Fit people have a lower incidence of many cancers.

Fit men have a 50% lower overall risk of heart attacks than sedentary men.

Women who have exercised a lot as teenagers have a lower osteoporosis risk than those who have not.  The risk of osteoporosis is further reduced by continuing to exercise after those active teenage years.

A slight fitness level is better than no fitness at all, but the fitter you are, the lower your risk of dying from a heart attack.

Most fit subjects are much less likely to have strokes, or to develop diabetes or high blood pressure.

Like resveratrol in plants, exercise is a natural defence of the body with a protective effect on the aging heart.
