Have you ever tried to remain in Condition Yellow for a full day? The looney bins are full of folks like that.
There are places and situations where you have to trust to $diety-of-choice, or to others to watch your back, flanks and front. And don't forget about sleeping with both eyes closed.
The question you probably should be asking is - was there anything that should have made you stay in DEFCON 3 or higher? If the bestthat was called forwas DEFCON 2, then you were OK. If it called for DEFCON 4 then we should not be hearing from you 'cause you're supposed to be dead.
