One of the Everest climbers that died from altitude sickness this week was a vegan on a mission to prove the vegans are as strong and robust as everyone else. Was attempting to prove the point by climbing mountains.
I wonder if they are on oxygen all the way up and back down (above 15,000 feet or so)? That is a lot of oxygen. I know that if you neglect to put on your oxygen in a small plane, you go to sleep about 18,000. Happened to my wife once. I was too busy flying and complying to tell her I had left 13,000 for 23,000. She didn’t respond to gentle prodding or voice, so I put a cannula on her and she was fine a minute later. Everest is >29,000 feet. Hard to believe it can be done, even with oxygen.
