Author's Purpose

Yodeling is a vocal technique once used by shepherds in the Swiss Alps. To yodel, you first have to find your normal, or "chest," voice, and your high, or "head," voice. Yodeling involves switching between these two ranges of sound, or registers, and finding the break between them. To begin, make an "ah" sound and move your voice from low to high, listening for the break. Try to keep your voice relaxed, but don't allow the notes to flow smoothly. Unlike other styles of singing, yodeling requires you to emphasize the break between notes.

I'd been fantasizing about this moment . . . for many months. But now that I was finally here, actually standing on the summit of Mount Everest, I just couldn't summon the energy to care.

It was early in the afternoon of May 10, 1996. I hadn't slept in fifty-seven hours. The only food I'd been able to force down over the preceding three days was a bowl of ramen soup and a handful of peanut M&Ms. Weeks of violent coughing had left me with two separated ribs that made ordinary breathing an excruciating trial. At 29,028 feet up in the troposphere, so little oxygen was reaching my brain that my mental capacity was that of a slow child. Under the circumstances, I was incapable of feeling much of anything except cold and tired.
