I really enjoy swimming! i am especially fast swimming backwards
Ah the self propulsion of a person through water
yup! do you like swimming ? most people i talk to all enjoy it
Yes I swim for recreation or exercise some others swim competitively or for sport or even survival 
oh you swimmed competitively too? I also did this! i enjoyed it so much and i won the race   
No I swim because its low impact and easier than other forms of exercise like running
