If I could afford it, I would totally go for plastic surgery! I think that if it's done for you, because you want it and it's just something you really want, then go for it. I don't think it's healthy when people get plasitc surgery to try and change themselves because of low self esteem.

I think that putting it on TV glorifies the plastic surgery, and only promotes the idea that there is an "ideal look" that everyone should strive for. By calling it "extreme makeover" the implication seems to be someone wanting to look different for the better; and I think that just perpetuates the stereotypes about what looks good and what doesn't.
