Read an article in Today's golfer a few years ago about a lad that played off a mid teen handicap until he had a bike accident. He smashed up his left arm and after recovering tried to start playing golf again, but just couldn't get through the ball properly because of the injury. Tried left handed and could now swing the club properly, got down to single figures in a couple of years.
It's make sense if you think about it. A right handed golfer is basically hitting the ball with his left hand and vice versa.
