And In the "Yet Another Quote From Mark Twight" Genre:

"Alpine climbers need maximum power from both mind and body. They train the mind to increase the awareness and grit, and the body to augment strength and endurance. The goal of physical training for alpine climbing can be summed up in one phrase: to make yourself as indestructible as possible. The harder you are to kill, the longer you will last in the mountains." -Twight from Extreme Alpinism

Classic, yet again.
