In 1953 Sir Edmund Hillary climbed to the summit of Mount Everest, the first man ever to do that. The man who impressed me most, though, was not Edmund Hillary but the companion who climbed the mountain with him: Tenzig Norgay.

Nobody ever hears his name. Yet on the way back down the mountain, Hillary fell and was almost lost. He would have been lost without Tenzig Norgay, who literally pulled him back up the cable and saved his life. Edmund Hillary lived to tell a great story because of the help of an unknown man. When someone asked Norgay why he didn't brag about it, he said, "We mountain climbers help each other."
