I'm not sure any of them wanted to be. There's really no choice. And due to the low oxygen and temperature, they keep pretty well up there.
That mountain is fascinating to me. I bet I've read 5-10 different books on it and seen just about every TV show about it. I actually had a friend who took the trek to Base Camp. Sadly, he said that the place is a shithole, but there have been cleanup initiatives since then.
Oh I didn't mean they wanted to die, just if they did they wanted to be left there. Like that was their biggest milestone/accomplishment or a statement of dying doing what you love.
Given the conditions ya I guess you don't have a choice but to be left there.
