10) Myth: Running is bad for your knees
A Stanford study found that knees of seasoned (and senior) runners were no less healthy than those people that do not run. However, that is not to say that running is without accident. Like any other exercise, form is important in preventing wears, tears, and degeneration of the joints and muscles. So while running itself will not cause any harm to the knees, having incorrect form while running may cause injury that can lead to degenerative arthritis.
