It has been proven through studies that college students who start exercising regularly in middle age live longer than college student athletes who lead an inactive lifestyle later. When you are exercising to promote longevity, persistence is more important than athletic talent.

In a study called the Harvard Alumni Study, researchers found that people who burned 2,000 calories a week through exercise had a life expectancy that was two years longer than that of individuals who led a sedentary lifestyle. This study examined the mortality rates of over 17,000 men who had studied in Harvard University over a period of 22 to 26 years.
