I like swimming usually for recreation but sometimes I do it for sport.
I love swimming also. I love watching the swimming events in the olympics.
Yeah swimming relies on the natural buoyancy. So for some people it can take time to learn.
I love floating. It comes easy to me. I could float in water all day longs.
Well buoyancy can change on basis of both body composition and the salinity of the water.
Yes. That is true. There is lake in the USA I think it is in Utah where you can float because of all the salt in the water.
most peoples bodies have a relative density of 0.98 compared to water. So that is why it is easy to float.
