Physical check-up & almost drowned

You know, I had been sleeping for 8 hours during the day after Columbo flight. I planned to get up early today to go to the hospital but I couldn't coz last night I went to bed so late. (slept all day so that I wasn't sleepy) I left home about 9.40 a.m. and arrived the Hospital at 11.20 a.m. (The traffic was bad) I was so hungry. It took about 3 hour to complete everything, blood, urine, lung X-Ray, etc... but the most I like was hearing testing. The doctor said everything is alright. I'm in good health and no virus B. In the late afternoon I went swimming at KU. The pool is deep and standard 50 meters. I haven't swum for a long long time,at least 5 months. I almost drowned while I was swimming about 35 meters, I felt tired at once. Luckily, the lifegaurd helped me in time. He saved my life!!!! And then I swam near the edge of the swimming and my friend kept looking at me all the time. Next time I should swim only the swimming pool nearby my house, not at the university. It's too deep.
