sorry nudediver, i generally agree with you, but totally disagree with your perspective of diving not being a sport. it is a sport, period. it is accepted as a sport worldwide, and always has been. if golf can be considered a sport, i fail to see why diving wouldn't be. all joking aside, it depends on what type of diving you are doing. there is a lot of deep diving, and timed cavern diving that you must be in great shape to participate safely. also, generally the better shape you are in, the higher degree of safety you have in diving. this has been proven in many studies of dcs, and ean depth limits previously done by the navy. you generally do not see any fat, out of shape people diving on wolf and darwin islands in the galapagos, north sulawesi or raja ampat. the conditions are too rough, and out of shape people just aren't able to complete a full dive in these conditions. certainly there are easy condition diving, where you need little athletic ability to negotiate the dive. but that is only one kind of diving, and i can tell you from experience, that there are many places where i have worked, where out of shape people have been denied a chance to dive certain sites, for this very reason. trust me, this is a sport my friend.
