Some (oebese) people, just lay themselves on the back. In accidents some people float, and others sink. -Obviously one part of people, with proportionally less sceleton in them have a density lower than water; and they float, the other contrary, and they sink.
That must be the prerequisite for swimming... So the question is "Is it possible for everyone to swim? -What makes it possible -the air in the lungs and/or the movements in the water?
If you float; how, then, can you sink? -If you sink; how, then, can you raise in the water? -How can you bring loads up to the surface?
