This is either the craziest or the bravest man I’ve ever seen. Adrenalin junkie and rock climber Alex amazed the entire world with his incredibly-dangerous ascent of Half Dome, nearly 2,000 feet — without a rope. My hands got all sweaty just by watching this video, I can’t imagine what he must have felt like actually climbing that rock knowing he had no safety equipment to protect him. Many people call him crazy or even stupid for putting his life at risk in order to perform his insane stunts, but ultimately, we all have the right to choose for ourselves.
