First I would like to ask exactly how dangerous is this sport? It seems looking around I see a lot of articles about killed scuba divers, I even watched a discovery special on the sinking of that big aircraft carrier for an artificial reef and one of the navies' own divers passed out and floated to the surface while checking the hull. Is this just people being dumb? I also backpack and when your up in the mountains its not exactly dangerous but you can get yourself killed if your stupid and try something your not skilled enough to do. Honestly I am a little nervous about scuba diving, I think drowning would be one of the last ways I would want to go.
