What do you think about such procedures? Are people who choose these measures for purely cosmetic reasons superficial and obsessed with looks? Are there some cases in which plastic surgery is justifiable and others in which it is not?

I think its your body so do what you want with it. Very often having cosmetic surgery can change someone's life dramatically for the better.

I think if you have a problem with a part of your body and its making you unhappy then go for it. But if your having surgery to please a partner as many people do this is wrong.
