In the actuallity, most of people want to change some part of their body because they aren't happy with their aspect.
In some cases, cosmetic surgery can be the solution, but the problem is people who are addict to cosmetic surgery. They want change their bodies to have other completely different that they are. In addiction cosmetic surgery has some risks.
I think you have to accept your body how it is, because if you change your body for other that it isn't yours, it mean that you aren't happy with yourself because you want to be other person different that you.
Each person is different, and you too, so you don't have to be other person different because you won't be happy with yourself, you will happy with the aspect of other person. You won't be really the person who people see.
