I love swimming, I usually do it with coordinated movement of my arms as a way to relax my body
Why do you love swimming?
Well I like it alot because I train to breath underwater and practice breaststroke swimming , In fact weeks after birth you are able to swim as an evolutionary response.
Can you swim a ocean?
Well sure you can but I prefer swimming in a pool because the water is much cleaner and calmer. 
Do you know Michael Phelps?
I sure do, I know hes a retired competitive swimmer and one of the most successful Olympian swimmers of all time, He won a total of 28 medals.
How old is he?
