I enjoy going swimming especially in this hot summer weather. Do you?
I'm not a good swimmer, but I enjoy the water. It is one of the top recreational activities, and in some countries part of a person's education
You can definitely enjoy the water even if you can't swim well. Swimming relies on the natural/non natural buoyancy of the human body. 
That is true, the body has a density of 0.98 which allows the body to float in the water.
