There are risks in the surgery procedures and some people have died during the procedures. When is it necessary think about a cosmetic surgery?
Cosmetic surgery isn't necessary... Most people forget that it is a surgery and don't see the risks behind it or are not enough informed by their surgeon. I've heard that there are some who take advantages of this new phenomenon to get money even if what they do isn't safe for the future(about after 5 years after the surgery). Getting older is part of life, having this kind of body too. Yes, for you and others it's not beautiful but there are some safer solution, beginning with psychology, and forgiving the body you have become...
Of course there are extrem situations, but I am talking about most people who don't really need cosmetic surgery but who do for a little touch of esthetic...
