I don't think this is a bad thing. I believe that if you've always had a big nose and hated being taunted for it, there was nothing wrong with having it adjusted to make you feel better about yourself. If you have "Obama" ears, and they bother you, get them fixed, and if you have wrinkles, and you don't like looking old, get a face lift.
I also realize it is not only skin deep. We are reading all sorts of ludicrous books on feminism that we may never have picked up 15 years ago (for me, it's Fear of Flying.. I'm not knocking Ms. Jong, but I would not have appreciated it in my 30s). We are determining our identities and one step further and more subconsciously, our legacies.
However, one of the best ways to keep the side effects of aging at bay may be something anyone can do, for free: get better sleep. The more we learn about rest and biology, the clearer it is that sleep plays an important role in keeping skin, bodies and minds young. In fact, it may be one of the most effective things you can do.
