I'm sure we'd all like to think we'd be fairly calm, cool, and collected in the face of danger. But there's really not telling how exactly we would react until we find ourselves in that sort of situation. And I think it's safe to say most of us would be absolutely terrified.
One man, however, was fresh out of cares when he found himself in the middle of an armed robbery, and even went so far as to casually light up a smoke while a gun was waved in his face. So It's safe to say this is the coolest guy in the entire world.
