“Regular running slows the effects of aging, according to a new study from the Stanford University School of Medicine that has tracked 500 older runners for more than 20 years. Elderly runners have fewer disabilities, a longer span of active life and are half as likely as aging nonrunners to die early deaths, the research found.
‘The study has a very pro-exercise message,’ said James Fries, MD, an emeritus professor of medicine at the medical school and the study’s senior author. ‘If you had to pick one thing to make people healthier as they age, it would be aerobic exercise.'” (Source: Running slows the aging clock, Stanford researchers find)
