If I remember correctly Bruce Lee damaged is lower vertebrae by doing too much weight on a good morning back exercise. This injury caused him to literally stay bed bound and flat on his back for 6 months. He couldn't exercise, but he found confort in reading plenty of self-help and motivation books to defy what doctors said was impossible. They said he be lucky to walk let alone do martials arts.

Willie Pep got in a terrific airplane crash that made the commision propose a 500k settlement as compesation but would mean he'd have to hang up the gloves. He managed to overcome his injuries and get back in the ring.

There are many other miracle stories, and there are books on it that are worth checking out.
