Getting old

I know I've been sort of ridiculously all-about-the-celebrities lately, and I'll knock it off soon, I promise. I've been procrastinating a lot instead of, say, writing insightful blog posts or buying school supplies, and if I wander the Web enough I always seem to wind up on the celeb gossip pages -- some sort of internet tractor beam, it must be. So this morning, I saw an item that said something to the effect of "Keanu Reeves, 40, is once again dating Diane Keaton, 59." And I know I was supposed to think something like, "Whoah, check out that age difference!" or "You go, Diane, getting a younger man!" or "'Bout time we reversed that old-guy-young-babe Hollywood double standard!" But all I could think of was: Keanu Reeves is 40? When the heck did that happen? Maybe it's just the fact that I'm sending my youngest to middle school that's making me feel so ancient.
