In Douglas Couplands Microserfs, the main character, Dan, at one point realizes that he has been neglecting his body for far too long. He then goes to the local Gym to do something about it (and discovers he is a "thin-fat" person -- you can imagine the ridiculing :)
Well, I don't like Gyms, but I do like Badminton, but haven't played in ages. So, I found a place with drop-in Badminton on Sundays (it turns out Badminton is not popular in Palo Alto -- go figure :), and I went yesterday to check it out. I played long and hard and now I am in tremendous pain.
I'm now sitting at my desk, and even the thought of re-adjusting my leg brings hesitation. My muscles are very angry at me I think.
