No, no, no, no and no!
I wouldn't want to face the risks of anesthesia (small, but there) and surgery unless it was necessary. The risks might be tiny, but there is still no point at which I would say that my desire for fake b00bs outweighed... anything!
Plus I'm happy with mine. They're not perfect, and there's loads that could be changed, but they're mine. I never want to look like any cookie cutter definition of what's currently 'perfect'. I don't like the look of fake b00bs either, and neither does DH.
All round - no benefits, but some risk to everything I hold dear! Not tempting...
ETA: I also want to be a role model for DD so that she has confidence with her body, and doesn't buy in to cultural fashions about what is currently beautiful. We all have different levels of what we would or wouldn't do, and I know some would say wearing make-up/ dyeing hair (both of which I do) are doing just that. But for me surgery is pretty extreme.
