Back when I was a caver (early 80's) I was trying to learn what sort of first aid might required. I had a buddy who'd been a medic in Nam, and he taught me the crude rudiments. Caving is bad, because you have to deal with 100% humidity, and endless mud and water-- kind of like a jungle only colder.
Yeah it's the humidity and mud that are bad about caving.
How about the DANG CAVE!
