I love to swim
swimming is very fun, swimming is the self propulsion of a person through fresh or salt water
Yes it is
Another fact is that humans can hold their breath underwater and undertake rudimenary 
Really?
Yes really, and swimming can also be formalized as a sport, it can be local, national and even international competitions.
I can't my breath for long
Same here, i did find another fact is that diving is part of the olympic games
