I was talking to a non-diver today and explaining a bit about why different gas mixtures are used and why we need deco/safety stops and she asked me how all of this information was determined. I answered that this knowledge was gained the hard way; that divers paid for it with their lives. She asked how many died along the way and I had no idea. Has anybody ever done a study of the number of divers who lost their lives to get us to the point that we are today with our gear configurations and safe diving practices? Anybody ever read any statistics like that anywhere?
