According to a new study from the Stanford University School of Medicine runners live longer, healthier, more productive lives than non-productive lives. No surprise there. But, it also showed that runners have no greater risk of injury--to their knees, their back, their ankles, or their feet. Indeed, 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.
Every non-runner I know asks about my knees--and then marvels that I'm not more hobbled than I am. At last, I now have the empirical data for me to point them toward as I encourage them to join me in hitting the road!
