Basically. They could have saved a lot of money on this study and simply asked you why. You are a yeti after all so I would be inclined to believe you on such matters.
Also, some of them get killed by YETIS!
Hey you kids, GET OFF MY MOUNTAIN!
TL:DR;
It's too cold and their brains got swollen up and bleeded into their skull on the way back down because they went too fast and exacerbated their worsening condition with exhaustion in the thin atmosphere.
also, primary breadwinners who had families back home to support where much more likely to die, also those who took the short "easy" path instead of the longer path through Himalayas where also more likely to die.
Great. Thanks.
the death rate for non-Himalayan climbers descending via the longer Tibetan northeast ridge was 3.4 percent, while on the shorter Nepal route it was 2.5 percent.

Woops. You are correct. My reading comprehension needs work I guess. No more reading scientific articles late at night before bed for me.
