I really enjoy swimming!  I especially love doing laps in the pool for exercise!  Do you enjoy it?
Me too! I really enjoy recreation, exercise, and sport swimming! How often do you swim?
I try to swim a couple days a week, especially when it is hot like it is here in Florida.
Good idea! It's a nice low impact alternative to activities like running!
I agree!  My knees are pretty bad from running for years!  What is a good distance you think I should swim for?
Any amount is good to start! As humans, holding your breath underwater I think is most important!
I agree!  Is it hard for little kids to learn how to swim?
Well humans can undertake rudimentary swimming within weeks of birth! Pretty incredible!
Wow!  How is that even possible!  Is that why some women have babies in the bathtub?
I'm not sure. But I know the natural buoyancy of the human body helps!
