I knew I should have gone to the gym.

I hadn't exercised in two weeks because I was letting myself recuperate fully from my cold. So yesterday, as the temperature was a balmy 26 degrees, I decided it would be a fine morning for a run. After all, it had been so long -- the last time I ran up Prospect Street against the wind in the middle of winter was the day before I got sick.

Guess who's sick.
