Swimming I swim 2 or 3 days a week at a swimming pool in a university. When I started to learn swimming, I drunk lots of water in the swimming pool. It entered through my nose, and I was pained as there was a stinging needle. After I've taken enough experience, this pain has disappeared and I became to enjoy swimming. Summer is particularly the best season to swim in a cool pool. When I felt hot, the cool water around me continuously absorbed the heat in my body. If I had been out of the pool and done any other physical practices such as running, I would have been easily exhausted by the hot. The only one deficient thing that there is no drinkable water in the swimming pool even though I could float on the water. After I swim more than 500 meters, I usually feel a terrible thirst. Except this only one shortcoming, swimming is a perfect exercise in summer.
