i can swim like a god damn fish. i could swim before I could walk. i waterski 6-7 days a week from april -October, and do a lot of scuba diving. been skiing my whole life and diving for 18 years. for one of my scuba certifications i had to tread water for a certain length of time with my hands above my head. holy shit that is tiring. i'm positively buoyant though, so with a deep breath a float pretty well.
