Sweet or sour, the choices
When five fingers unite
Time resets these flavors
Unfettered by the mind’s instant recoil
Only a few people have succeeded in climbing Mt. Everest without oxygen. The first to do it solo and without oxygen was Reinhold Messner in 1980. On reaching the summit without oxygen, his thoughts were: "In my state of spiritual abstraction, I no longer belong to myself and to my eyesight. I am nothing more than a single narrow gasping lung, floating over the mists and summits." It is remarkable he was able to think, let alone express such profound thoughts at that oxygen depleted altitude. At heights above 25,000 ft., called the “death zone”, experienced climbers, even with supplemental oxygen expend great effort over 10-12 hours to traverse a single mile. Our physiology is most suited for terrestrial life close to sea level. From this perspective, humanity is an extremely reclusive member of the cosmos. Sheltered by the sky and dependent on air, we can only go where the lungs are fed oxygen.
