When we're in college, staying out all night and sleeping the day away is totally acceptable. But as we get older, our hard-partying ways can soften. The older I get, the more I worry about getting enough sleep, as opposed to getting enough booze. Don't get me wrong: I can still pull out all the stops when I need to, and I hate to pass up a good party! But most of the time, I find that my social obligations involve more nice dinners, happy hours, and conversations, coupled with turning in early.

And you know what? It doesn't really bother me, which is possibly the clearest sign that I'm getting older. Do tell: What about you? Did you used to be a big partier and, if so, have you calmed down over time? What parts of partying make you feel old now? If you're still in your party phase, how much longer do you think it will last?
