I know it's probably a fad by now but I can't resist the prospect of being able to answer the question:

"Hey, you look like you've gotten into shape, what's your secret?"

with:

(dryly) "Video games."

For the past few days I've been playing Wii sports for at least an hour or 2 at a time and at the end was left sore and in need of a shower. Oh, and I already lost 2lbs.

I guess we'll see what happens. Will I keep up this weirdly compelling practice? Will I make periodic posts with updates of my progress?

Only time will tell.
