Wii Fit

I sat on the couch with a pen in my hand. I was supposed to be editing my book proposal, but instead I was watching April stand on a Wii balance board.

The balance board is an accessory for Nintendo's Wii video game system, and it's a white slab that looks like a household weight scale. The board itself is a sensor that keeps track of your progress while you exercise.

April was standing on the board and pointing the Wii remote at the TV to set up her profile so that she could begin her exercise routine. The board measured her weight first, then her center of gravity, and finally calculated her body mass index. The number popped up on the screen.

"Hey, we have the same body mass index," I said, trying to be optimistic since April's pregnant and beginning to show.

April grinned at me over her shoulder.

"Yeah, but I'm pregnant," she said. "What's your excuse."
