When I was 7 I learned how to tread water. It didn't take long for me to catch on. I've been treading water for 10 years now. It's hard to keep your head above water when the waves are this heavy. It's even harder to keep your head above water when you want to drown. There's no one to save you if you sink. There isn't any warning for a wave. You just keep treading. -N.P
