I learned at a very young age how to swim becuase we have always lived by the ocean. Then in high school I did synchronized swimming for a while. But that was years ago. Every time I swim now I don't seem to like it as much. And chlorine make me sneeze like nobodies business!
I think it is so cool you want to learn. It might be you will like it better then anyother other sport. It is kind to your joints. No impact. Keep us up on how you do with it!
