I do generally agree that terrorism isn't a threat worth changing our lifestyles over.

However, I wonder if it's a little unfair to average out the probabilities and compare to something closer to an actual random event, like falling vending machines; surely, a terrorist attack is significantly more likely to occur in a place like New York than Middle America, no?

I'd really like to see something like what's the probability of being killed by a "falling vending machine" IN NEW YORK vs a terrorist attack IN NEW YORK, than something country wide.

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).
