Up there you cannot think a lot, everything is going slow in the brain, the decisions are mostly like, 'Is this going to kill me?' If it's yes, you go down, if not you continue. In the mountains you need to be rational. Stress is just a waste of energy. The physical suffering is something you know will come so it's not really a question. You need to fight to survive. You can't abandon yourself because then you die.
