FYI, getting killed by falling vending machines isn't a random event. It happens because people are rocking vending machines back and forth, either to knock loose a stuck purchased product or just to try to steal from them. If you get killed by a falling vending machine it's because you were doing something stupid.

So long as you never rock vending machines, and you shouldn't!!, you are way more likely to be killed by a terrorist, even though the odds of that are incredibly low (one in many, many millions).
