I like to swim for fun, its very popular as a recreational activity.  What about you?
I was a competitive swimmer for 9 years. I ended up ripping my rotator cuffs in high school and had to quite. I was very sad about that and I miss swimming a lot. 
Oh neat, what kind of competitive swimming did you do?  Freestyle or a medley relay?
I mainly did Freestyle. The 200 meter was my favorite race, but I also did the 100 meter occasionally. It was the Butterfly that tore my shoulders, however. One of my couches gave me a 500 meter butterfly drill as a punishment, and that's when my shoulders started swelling every time I swam.
That is sad, sounds like you were on your way to being the next Michael Phelps who won 8 gold medals at the 2008 Olympics.
