I really enjoy swimming!  Do you ever get a chance to swim?
I do not swim much but when I do its in salt water.
Same here since I live in Florida!  At what age did you learn?
I learned when I was 6. I did it mostly for exercise.
That seems like a good age to learn.  Swimming does seem like a good exercise.  I should try it
Yes but you have to be able to hold your breathe.
How long should I be able to hold my breathe for?
I am not sure but you should know hiow to hold your breathe cause its a evolutionary response.
