In the past five decades, nearly 10,000 men and women have tried to climb Mount Everest. Less than 500 have succeeded. Those that do are granted new views of the world and of themselves. But for every 60 climbers that leave base camp in an average season, only four will reach the summit... and two will die. Why is it that so few make it to the top? The answer lies in a struggle with the elements.
