Well, there are a lot of areas to look at with cosmetic surgery. There is the question of how young is too young- I believe Australia doesn't have a minimum age for girls to undergo breast augmentation, so long as you have parental permission and the surgeon is willing. There's cosmetic surgery as entertainment, with Extreme Makeover, The Swan, Dr 90210 (on foxtel) etc. The question of whether cs is a good or bad step to take when dealing with self esteem issues- some think so long as it helps them its positive, while others feel people need to learn to accept themselves as they are.
Any one of these questions would be sufficient as the basis of a PIP, I believe. And thats just two minutes of thought. Spend a couple of minutes brainstorming, see what aspect of it interests you most, and then decide if you can see yourself spending three months working on it.
