recently, I finished a book called into thin air. after that, I don't think I want to try Everest.
the dangers of Everest include avalanches, crevasses, ferocious winds up to 125 mph, sudden storms, temperatures of 40°F below zero, and oxygen deprivation. In the ?death zone??above 25,000 feet?the air holds only a third as much oxygen as at sea level, heightening the chances of hypothermia, frostbite, high-altitude pulmonary edema (when the lungs fatally fill with fluid) and high-altitude cerebral edema (when the oxygen-starved brain swells up). Even when breathing bottled oxygen, climbers experience extreme fatigue, impaired judgment and coordination, headaches, nausea, double vision, and sometimes hallucinations. Expeditions spend weeks, sometimes months, acclimatizing, and usually attempt Everest only in May and October, avoiding the winter snows and the summer monsoons.
Between 1921 and 1999, Everest has been climbed by more than 900 people from twenty countries. More than 150 have lost their lives, the odds being one-in-six of not making it down alive. The dead are left where they perish because the effects of the altitude make it nearly impossible to drag bodies off the mountain. Those ascending Everest pass through an icy graveyard littered with remnants of old tents and equipment, empty oxygen canisters, and frozen corpses.
