I love swimming in fresh or salt water in the summer.
I love to swim too! I usually do in a pool, but will be swimming in the ocean this weekend, Florida bound!
That sounds exciting! How long can you hold your breath underwater?
Not very long! I don't really like to go underwater too much, it burns my contacts. 
Oh I see. I love swimming since its a “low-impact” activity compared to land activities such as running, especially since I have a bad knee
