When I was young I am WAS not so active to learn any kind of sports, so I did not learn how to swim for long time. In my high school days I studied in the school in the summer vacation period. From the 1st grade of school, I prepared university exam. My school had a swimming pool, and opened everyday for the summer vacation period. A lot of people were swimming. After I swum, I used to study in front of my desk. Main subject was Mathematics, English, Korean others was Science including Physics, Chemistry, Biology and Geology. After swimming, I usually sleep one hour crouching on my desk. My friend just taught me how to start swim. When I was in the water holding breadth for swimming lesson, my friend were at play bunting me. I was drowned for a while and drank little water.
