Scared of heights? This Chinese air conditioner installer clearly isn't. The video shows the man carrying a hefty A/C unit. He's wearing a harness, but it's unclear what the harness is connected to.
The video looks scary enough when he straddles two ledges to get to the A/C bracket, but then the camera pans down to show a gut-twisting view of the fall he would make if he slipped.
If that isn't enough, he looks like he was just wearing his socks, presumably to avoid scuffing the white ledges.
