Today at the pool, while I was guarding, a patron that is known for having had a seizure while swimming at our pool a few years ago came into swim. He is a regular at the pool and swims about 80 laps (25 yard laps in this old pool) every time he swims. He has a worker that comes with him just to make sure everything is okay and to help him get around. He was the only swimmer in the pool. After about a half hour of laps while he was in the middle of the pool he suddenly stopped swimming with his face down in the water. It was a little odd because he was vertical to the bottom, but nevertheless he was face down. His aide and I were both alarmed, we both figured he was having some kind of seizure even though it would have been just a "partial" (he wasn't shaking). He lifted his head up for a moment and I called out to him to see if he would respond but then his head went back under. I leaped into the pool -- a pretty good stride entry too I might add, and found myself staring eye to eye with a very confused swimmer. I asked him by name if he was ok. He responded that he was; by the look he gave me I think he wondered if I was. It turned out that he had stopped to look at his water sock that was in the process of falling off. He was standing there face down trying to fix it. He never heard me call to him from the deck. I caused myself a lot of worry for nothing, and got wet too, but in the end I'm really glad it was nothing.
