As I was watching How Do You Know last week, I found myself thinking that Reese Witherspoon was looking a little old. I suppose my mental image of her is still stuck in the days of Election and Legally Blonde, even though the latter of those two is now nearly a decade old. Still, when I think of Reese Witherspoon, I think of the fresh-faced, perky young woman she played in those movies, so seeing her now in a movie that really dwelt on the extreme close-ups, I couldn't help but see the little lines starting in her face and think about how time marches on for all of us.

Of course, I realized very quickly after that that she and I are more or less the same age. She's 34, I'm 31. The difference is pretty negligible at this point. That realization was quickly followed by another: that my mental image of myself is also stuck in days past.

I don't actually think of myself as a kid anymore. No, seeing teenagers at the mall, for example, or college kids in the beachside parks, I don't actually feel like I'd fit into those crowds anymore, nor do I have any particular desire to do so. But more and more often I keep having these weird moments where my age kind of hits me in the face.

Like the other day, for example, I was watching this clip of Marc Maron on the Letterman show, at the end of which he talks about how one way he knows he's getting older is how teenage girls see him. It's a funny bit and I laughed, but later I realized that he was 33 at the time, and, yeah, that's pretty much where I am right now, too. (To quote Maron, "Now, don't misunderstand what I'm saying, I'm not saying I want to have sex with teenage girls, I'm just saying, 'Hey, throw me a bone.'")

Or when I was watching the Rose Bowl last weekend with my uncle and realized that not only am I way older than any player on that field, but I'm actually older than the vast majority of pro sports players. I pointed that out to my uncle and he burst out laughing.

Mind you, I know I'm not actually old. I did find one gray hair in one of my sideburns a while back, but I just keep my 'burns shorter these days. But, no, I'm not saying I'm old. It's just weird to think about how I'm not actually young anymore either.
