Are you a dedicated builder who thinks your job is tough? Imagine being the man seated in the crane atop the Burj Dubai, the tallest building in the world. Because it takes so long to descend back to the ground, the crane operator, Babu Sassi, has taken to sleeping in the tight confines of the crane at night. Just thinking about that makes my hands sweat. One commenter in a chat room quipped, "[Sassi] must be a real expert at cranes or totally insane." I'm going with the latter.
