I know how you feel; it seems like the last year or two have been very, very aging on the exterior. I used to be mistaken for 10 years younger, and now people don't raise an eyebrow when I tell 'em my age (32). My virtual age on RealAge tells me I'm 5 years older.
I think it has something to do with all this sitting at the computer...
More dancing sounds like a good solution. We're all gonna get older, it's just how gracefully we do it that makes all the difference, right?
