I think the only kind of cosmetic surgery I would personally consider for myself would be a breast reduction (or at least I'd make it so that they both matched!
); I'm ridiculously well-endowed (and weight loss doesn't appear to be having any impact on that ...) and I do have some back pain. Plus, on a more vain note, it'd be nice to be able to buy the cute, flirty bras that smaller-chested girls get to wear. I have some sexy bras, but I pay a small fortune for mine (I just bought three that weren't grandmother-ish, and it cost me close to $400!).
Aside from that, though, while I have things about myself that I would certainly love to change, I'm afraid that if I change one thing, I'll keep finding other things about my body that make me unhappy. Right now, I just dislike my nose. Who's to say that, after getting a nose job, I won't suddenly become fixated on my chin, or the shape of my eyes? And I could, in theory, use cosmetic surgery to get rid of my saggy, pouchy stomach and flab-tastic arms, but at this point in my life I'd rather work on getting rid of them the natural (albeit frustratingly slow) way. I'm not going to say definitively that I won't change my mind ten, twenty years from now, though.
I once worked for a cosmetic surgeon, and it was a real eye-opener. I think the majority of people seeking cosmetic surgery aren't obsessed with bigger boobs or a flatter tummy; most of the people my employer saw were there for very small, but very intensely personal reasons. One was a high school friend of mine who had smashed through a glass window and horribly scarred up his face. Another was a girl I'd gone to grade school with, whose breasts were so lop-sided that it was noticeable no matter what she wore. And another was my mother, who had had a thorn embedded in the back of her hand; it got infected and her hand was badly scarred -- the doctor I worked for specialized in hands, and now you can scarcely tell my mother had had anything done.
When I was younger, I thought cosmetic surgery was pathetic, and that the people who got it were sick and vain. Now that I'm older (and, hopefully, wiser), I don't feel that it's fair of me to judge others just because I'm reasonably content with my body the way it is. I admit, I shake my head in dismay at the woman who's made herself into Barbie (or a human cat), but ultimately, it's your body and your money. If larger breasts, a perfect nose and a smooth tummy (or looking like a living Barbie Doll) will make you happy, do it. But I think you need to seriously ask yourself -- because cosmetic surgery is pricy, recovery can take a very long time, and the effects are more or less permanent -- if these changes will truly make you happy,
or will you, like me, keep finding new things about yourself that you don't like.
