I spent six years in the US Navy, and never learned how to swim before or after I joined. They give you a basic swim test, administered by Navy SEALs. It involved (at the time, mid-90s) jumping from a 25ft high diving board into a pool, and treading water for a bit. This simulated having to dive over the edge of a ship in case you had to evacuate. Anyway, I climb up, get to the edge of the diving board and just freeze. A very unhappy SEAL actually had to climb up and push me off the board. I must have been a really sad, pathetic case because one of the other SEALs doing the training pulled me aside and worked with me for the remainder of the day so that I could pass the swim test later that afternoon. Kinda makes me wish I had learned when I was a kid, or had the time to learn now. At least I can still tread water.
