Now that I am working emergency response full-time, I have noticed something that I haven't seen in a long while. I've been working 9 - 5 (basically) since mustering out of the Marine Corps. A few years ago I began volunteering as a firefighter and EMT. Now full-time as an EMT, I have noticed that the "atmosphere" is basically the same as when I was on Active-Duty - we're dragging through stretches of complete boredom, punctuated by brief periods of excitement. (The original quote is for "sheer terror", but that's not the case currently because I'm not facing armed opposition and dodging munitions anymore.)
I am again polishing my boots, pressing my uniform, and cleaning equipment and buildings over and over waiting for the alert for action.
