I enjoy to swim,   the self-propulsion of self through fresh or salt water.
I love swimming in the pool!
I prefer to swim at sea. Something I find amazing is tha human can hold their breath underwater and swim in a rudimentary way within weeks of birth.
I know! do you know how to swim?
Yes, and I believe everybody should know for safety reasons, in fact, in some contries, swimming lesson are a compulsory part of education.
really?? what are those countries? do you know?
I don't remember, but it make sense.  In the other hand swimming is one of the top recreational activities and formalized sports.
It does make sense! I wonder if there are any baby swim lessons so my son could learn how to swim
I know there are swimming lessons for babies, I've seen it on TV, how old is your son?  swimming relies in the natural buoyancy of the human body.
he is 15 months and loves being in a pool
