I remember going to a talk by Doug Scott, maybe 25 years ago, where he talked about climbing past a body on his way to a summit somewhere (not Everest, as far as I recall). He described the body as though the climber had sat down to have a rest and look out over the view of the surrounding mountains, and just never got up again.
The mental image of it, and the matter-of-fact way in which he described it still stays with me now.
I think you need to be a different breed to play in the high mountains. A good friend of mine who climbs found two (dead) climbers who’d fallen off something in the Alps. “Heads on backwards stuff” was the way he described what he’d encountered. He and his mate got down off the mountain, informed the relevant authorities, and then got on with the rest of their day. I can say with absolute certainty that I wouldn’t respond in the same way.
