|Man aims to swim across the Pacific Ocean
A 51-year-old French man will swim 9,000km across the Pacific Ocean. He started on Tuesday. He will swim for eight hours a day for six months. It is dangerous. There are sharks. The ocean is cold. He will be tired and lonely. He said being strong mentally was important. He will "always think about something positive."
The man trained for six years. He swam every day. He is in great shape. He is doing the swim to get people to think about climate change, and about how much plastic there is in the ocean. Doctors will check his body to see how so much exercise affects the heart. After he swam across the Atlantic in 1998, he said: "Never again."
