So I did!
I used to play soccer competitively but pulled all the tendons in my left knee in a bad accident during a game in tenth grade. For some reason we didn't get it treated with sports medicine at the time and I more or less couldn't run for five years. Every year or so my knee would give way and its condition would get worse again. In Waterloo I played softball with no injury for three years. Encouraged, I tried playing soccer again three years ago. The knee gave way again, and I finally went to a doctor and then into physical therapy.
Right now I'm not in very good cardio shape so running for very long left me very out of breath. In order to avoid my exercise-induced asthma kicking in, I took a nap from 9 to 10 and then did a warm-up workout down in the basement. I met the rest of the team at wide world sports arena and we had a pretty good game! I've never played indoor before, so I'm not used to passes off the wall and kicks that hit the net resulting in free kicks and such, but the astroturf was pretty good to run on and though sprinting left me out of breath at the same time it was fun to find out I *could* sprint just about as fast as anyone on the other team. I did some effective intercepting of the ball and generally felt like I played pretty well for my first game in years. :)
It was fun. We'll be playing friday nights all spring (not always that late - next week's game is at 9). I don't know if we can still add more players but we could especially use more women (in co-ed there always have to be at least 2 women on the field and we only had 3 last night, so it was a little brutal), so if you're interested let me know.
