How not to swim: During your first lesson you kick your legs so hard in the water in a futile attempt to keep warm you end up pulling a muscle in your left leg.
It reminded me of an injury I suffered in junior high, which I’ll get to in a moment. For the swimming, the muscle became very tender after the lesson had ended, so I figured it would be best to let it rest for a couple of days (lesson #2 was only two nights later). I now have a duffel bag and am getting goggles for lesson #3, though. I’m sure it will be totally awesome and flawless.
The junior high injury was during a gym class in the dead of winter, temperatures below freezing. We were doing orienteering in some local woods and at one point I carefully climbed over a barbed wire fence, wearing only a sweatshirt, a pair of shorts and my trusty running shoes. During the science class that followed, I felt something warm on my leg and pulled up the pant leg to reveal a prominent gash where the barbed wire had sliced through. There was much blood. I marveled over how the cold had completely masked this, then went to the nurse because the science teacher did not like the blood all over the place.
