This is a belief that a friend of mine had right up into her early twenties. We were talking about how little lizards or as we call them in Australia "Gecko's" can loose or let go of their tails if something grabs them by it and then grow another tail. I said wouldnt it be good if scientists could work out how they did it and somehow humans could do the same thing if we lost an arm or a leg, my friend burst out with "but I thought that we could grow back our arms or legs if they got cut off" no wonder everyone called her dilly Lee.
