I occasionally join some friends as a substitute player in a floor hockey league. The fast twitch muscles are not really up to snuff anymore (if they ever were). I like to start, and keep moving at a reasonable clip. Stopping and starting and stopping and starting and so on… not exactly what a 3 mile run twice a week prepares you for. Lots of interesting stuff to read and (maybe) comment on, but not tonight. Need to get in bed about… now.
