I don't think that I would ever have plastic surgery, but I certainly wouldn't hold it against anybody who did. The only thing I would possibly consider is breast reduction, but really the best way for me to get the girls to be a little smaller is to lose a few pounds.
As for facelifts -- maybe my story will change when I get older, but I don't think I would ever do it. Granted, people say I look a lot younger than I am and my mom looks great for her age, but when I do end up getting a wrinkle or two, I want to show them off with pride. I don't think there's anything wrong with getting older, and as long as you take care of yourself and stay out of the sun, you can be beautiful just as you are.
