A recent study by Stanford University School of Medicine has found that regular running slows the effects of aging. They tracked 500 older runners for 20 years and determined that runners experienced fewer disabilities then the non runners that were also tracked. Both groups in the study started to become more disabled after 21 years of aging.
“Runners’ initial disability was 16 years later than nonrunners,’” Fries said. “By and large, the runners have stayed healthy.”
