My sistagirl dragged my sorry ass to an aerobics class Saturday morning. Early morning. 8:30 in the morning, to be exact. She got me by telling me about the music: "It's all, like, BeeGees, and disco and totally '80s. Just twist a bandana around your forehead and find some spandex and it'll be great." And I was all, like, yeah! That WILL be fun.

What drugs were flowing through my bloodstream? I hated aerobics classes in the 80s when I could still do them, before my knees just crumbled into bone meal inside some post-sell-date cartilage. I hated disco. I still hate disco. I spent the late 70s and early 80s pogoing at punk bars, and to this day have never once, not even for a minute done the Hustle.

And I went to an 80s revival aerobics class. Somewhere in the middle, as I was blowing like a aged cart horse trying to run the Preakness, and folding up with my head between my knees so I didn't pass out, I started cursing my friend. The disgustingly skinny, cute and preternaturally perky instructress kept bouncing past me and saying things like "Keepin' it movin', good work there in the back."

If I'd have been able, I would have cursed her, too. As it was I could barely lift my hands to shoulder lever to flip her the bird when her back was turned.

I'm going back tomorrow. But that class will be yoga. I am a master at the corpse pose.
