I enjoy swimming in my pool. I find it's not only fun for recreation, but also great for exercise. Do you like to swim?
Neat! Do you have a diving board? I like swimming, especially when there are other people around to hang out with! 
I don't have a diving board, I have an above ground. But, I think it's pretty cool we can start holding our breath under water within weeks after we're born!
That is neat! How long can you hold your breath for? I remember trying to get past 1 minute 40 as a kid.
I can't really say, I haven't tried in awhile. I know swimming is one of the more popular recreational activities in summer though. Some schools make it mandatory for their educational curriculum, which is a good idea.
Yeah! I like the public recreational parks with all of the different water slides. I had no idea swimming is mandatory in some places!
Yes, it some countries, it sure is. I think everybody should know how to swim though. It's considered a 'low impact' sport, but I imagine for competitive swimmers they don't think so!
