Swimming is one of my favorite activities to stay in shape, do you ever swim or know much about swimming?
Swimming is the self-propulsion of a person through fresh or salt water, yeah but i like salt  water swiming 
That's interesting, do you have a pool around you with a lot of salt water? I would think that would be hard to find.
Yeah but i mean more like in the ocean. cool fact Locomotion is achieved through coordinated movement of the limbs.
