does this mean it's working?

Some of you might remember that for my 2005 New Year's resolution, I bought a used PlayStation off eBay, determined to actually get some exercise by playing Dance Dance Revolution. I played DDR twice and then forgot about it. A couple of weeks ago, I dragged the dancepad out and started attempting to play a little in the mornings before work.

Well, I didn't get to today, and I'm sleepy, cranky, and overall pissed off. Maybe DDR does count as exercise after all and my body is cranky without it. And maybe I am just addicted to the insipid dance-pop and jumping up and down scaring the cats.
