Poor guy. Apparently he was sure that he cut the tangled lines free with his shears but it was a "Rapture of the Deep" dream/hallucination, and he never did Was there ever an HD version of this video released?
The simple reason that the bodies of dead climbers are scattered about Mount Everest is that it's too dangerous and difficult to try to remove them. Reaching the summit of Everest is a physical challenge unlike any other on Earth. To attempt to bring a dead body or a stranded climber down would take too long and likely leave the climbing team stranded overnight. This makes rescue attempts virtually suicidal.
I've always wondered how climbers shit and piss at those heights
