Here's a scary thought:

Think about all the times where you've gotten into a near-accident. Even something simple like stumbling down the stairs, or slipping on ice. All the times where you cross the street a little early, and then run out of the way of a truck that's way too close, or brush up against the side-view mirror of a moving car. Think about all the times where you've told your friends about this, and said "Man, I coulda died."

Scary, huh? I thought about it, and I had this long list of those moments. It really makes me think, y'know?
