A buddy of mine (he is non-diver, but knows everything) and I were having a few drinks discussing diving, the discussion went on (long story) but the jist of it was, can it be physically possible, (or should I say medically possible) to perform 900 dives in a one year period. I dont' see why not, although you may be very tired and 'water logged' with the proper computer 900 dives in a one year period should be possible. Who is right, myself or my 'non-diver' buddy??
