Swimming in four hours

Jianguo Du, Yi Chen and I had been swimming between 13:00 to 17:20. It's the longest period of my swimming history. I felt little tired. I believed I would get up late tomorrow morning.

I met an elder man again. I met him in my all four times swimming. He said he was 75 now and swam every afternoon. He could swim 1500 meters. We three all admired him.

Good health is the basis of all. I felt good at swimming.
