I had an internet friend who claimed he had lenthened his legs by an inch and a half by doing "weighted kicks" while training for martial arts. Years ago when I had an interest in hypnotism I also read a strange story where someone claimed to have hypnotised this farmer in his early 20s who was scared to grow up, after curing him the guy was meant to have grown 5 ins overnight. utter unproved anecdotes both of course,
