I agree that possibility is always hovering over us, Jed. But it's utterly unpredictable so you can't build your life around it. It's like waiting for the magnetic polarity to flip, or an EMP to hit, or that good ole asteroid with our names on it. So I choose to to live my life and ignore the bomb. Where I live will be one of the first places hit, so if it happens I won't even know it. I guess that's my version of "radical acceptance".
