You probably shouldn't ever swim in an ocean or river again.
Or get on a plane.
Or drive a car.
Or go to sleep (people die in bed all the time you know).
Or...
Good comparison.
I agree, choosing to do these things is way more risky than working in the World Trade Center.
I accept the risk on things I have to do. (Pick up milk from the store; sleep at night.)
I mitigate the risk on things I choose to do. (Don't swim in riptides, or stray too far from shore, or splash about with seal fat in my pockets)
Where there is risk, and no way to mitigate it, and I'm free to choose? Why bother with the headache? (I do not skydive, and have no interest in doing so. I do not fault those who choose to partake. Ditto WTC jobs.)
Fair enough, I think you are over representing the risk you are "mitigating" by not working in a specific building.
Yes but you're over-representing the risks of plane rides, for one. 1 in 1.2 million plane flights end in a crash and the average American's annual risk of dying in a plane crash are 1 in 11 million; there's no way the odds of another lethal terrorist attack on the new World Trade Center during X years of employment approach anything like that. September 11 wasn't even the first terrorist attack on the towers.
Also, I think when people compare mortality rates they forget to factor in the horror of the incident itself. Yes, car crashes are much more likely to kill you, but (1) you can mitigate the risk; and (2) the incident would likely occur out of nowhere and likely kill or incapacitate you quickly. That's a much more pleasant thought than facing the choice between jumping from a 100 story window to your death or allowing yourself to be burned alive. There's value not just in avoiding death but in avoiding that particular kind of death.
