Kadame and Pundit, it's not so simple - where would you draw the line? Sex change for instance, medically you find the younger the subject the better the outcome. Sex transfer surgery works perfectly upto 15, when the body is not fully developed in late puberty. Intro boy hormones to a girl at 12 and he turns out foolproof. Do it later and you have a funny-looking manly woman like Caitlyn Jenner. Most transgenders wish it was done way early.
