Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions, but you really climb for the hell of it.

~ Edmund Hillary

Ever since the morning of May 29, 1953, when Tenzing Norgay and I became the first climbers to step onto the summit of Mount Everest, I've been called a great adventurer.
