Alex Honnold's death-defying ropeless cliff climbs


The New York Times profiles 29 year old Alex Honnold, who climbs sheer cliffs without using ropes.

Climbers know that fear itself can cause a climber to panic on the side of a cliff. To get a sense of the experience, try a thought experiment: Picture hanging from a pull-up bar in a playground, with your toes inches off the ground, and feel the calm security of your grip. Now imagine standing on the edge of a skyscraper with that same pull-up bar suspended at eye level two feet in front of you. Lean forward to grab that bar and let your feet swing free, so that you're hanging by your hands. Look down. How's your grip now?
