Is there any proof that exercise increases longevity?
Moderate exercise extends your life. A famous study looking at almost 17,000 male alumni of Harvard University showed that as the activity of the men increased, their death rates decreased. Men who expended at least 2,000 calories doing moderately vigorous exercise, such as playing tennis or jogging, lowered their overall death rates by 25-33% and decreased their risk of coronary artery disease by 41% when compared to the more sedentary alumni.
