Climbing to the top demands strength, whether it is to the top of Mount Everest or to the top of your career.

I wanted to reveal how genetic code is translated into protein. I knew a great application could be for antibiotics, since half of the useful ones target the ribosomes, but I didn't believe I could contribute to it. It was like the next Mount Everest to conquer. It was my dream to contribute something to humanity.

Most of the planet's terrestrial surfaces are visually accessible through video cameras and satellite imagery, if not physically within reach. Even the approaches to Mount Everest are now littered with human debris. One can drive to Timbuktu, which for centuries was synonymous with inaccessibility.

I am not sure the others are as committed as Rob Hall and Scott Fischer. I think there is more business now, and I know it will be impossible to stop this Everest business.

What we can do now is contribute to a clearer understanding of what happened that day on Everest in the hope that the lessons to be learned will reduce the risk for others who, like us, take on the challenge of the mountains.

I'm way more in my head acting than I am when I'm writing. So there's a weird love/hate on both ends. But writing, as tough as it is, I get so much more out of it. It's like climbing Mt. Everest.

Finding meaning in global mass phenomena can be difficult because the phenomena themselves are invisible, spread across the earth in millions of separate places. There is no Mount Everest of waste that we can make a pilgrimage to and behold the sobering aggregate of our discarded stuff, seeing and feeling it viscerally with our senses.
