It may sound unlikely, but scientists recently decreed that judo could have incredible health benefits older people.
Along with other martial arts, judo involves learning how to control yourself when you fall in order to avoid injury, and the experts believe that men and women with osteoporosis could benefit from mastering these skills so that they can avoid the risk of injuries.
