I think it's a complete waste, unless certain circumstances are present. Like these celebrities---they don't need it. They're actors, most of them, they need to be able to move their face around, they need to look human. The plastic surgery doesn't help. Some of them are starting to look very..unhuman.

But otherwise---I'm compltely against it, unless the person who wants it has been in n accident, or one of their features is really, seriously hurting their self esteem. No vain teenagers, please.
