Holding my Breath

I was swimming yesterday for my cardio. After spending twenty minutes doing various kinds of swimming laps, I did a few more but with some rest between them. Finally I held my breath and swam the length of the pool. The first time I made it about three-quarters of the length. Then I made it the whole length. That was pretty cool. Now I have to find out from Russell if his class has to go there and back holding their breath.
