When a man or a woman has a tattoo or does something to their hair, its generally done for a reason other than trying to get a better score in a sporting event. After all, a tattoo is permanent and the athlete's descicion to get it probably had nothing to do with his or her sport. But when you see a female gymnast outside of competition, she will not be wearing the massive amount of makeup that she wears during competition. Its not a vain little thing but an attempt to increase her score.
