You know, the whole idea of going under the knife for something cosmetic scares me. Surgery is just so dangerous sometimes.
However, I'm not really against plastic surgery (like my opinion really matters

). If some part of your physical body really bothers you, and you can afford it, I don't see why you shouldn't correct it.
Just please make sure you get a good doctor. There are websites around that have a list of questions to ask a surgeon to make sure he or she is board certified and has had the training to take the best possible care of you. Just make sure you follow doctor's orders and keep your expectation realistic.
Good luck in whatever you choose to do, but just remember to make choices because you want to... don't let other people have too much influence on you.
