Why? Were you in an accident and need repair? Or, is it just vanity? Why not accept who you are, where you are in life as normal, and just do your best to be healthy? Confidence is one of the most beautiful things a person can wear. Why not try that first? Why listen to those who tell you that "youth" is something to strive for? That is so shallow... instead, accept your place in life, treat your body with respect by feeding it well, giving it plenty of exercise, and believe that you are more than just an image starting back at your from the mirror. Accepting who you are without alllowing society to manipulate you into procedures that make others rich and you poor for vanity's sake.... well.... how sad.
