Mythbusters #27 - Running is bad for your knees

There are many people out there who are avoiding running because they believe that the constant impact is bad for their knees, and may lead to problems later in life. However, a 14-year Stanford University study of 800 runners and non-runners who were approaching old age showed that former runners had 25 per cent less knee and other musculoskeletal pain than people who had led sedentary lives. These findings add to the evidence that ailments associated with ageing can be reduced by participating in regular aerobic exercise.
