One thing you don’t think about most of the time in terms of disasters is boredom. If your mind becomes even a little dull over time, you’ll start to make worse decisions, or succumb to the anxiety, for example, of being stuck inside for a week during an awful blizzard.

That’s why I always keep a book that I enjoy in my emergency bag. It might seem an odd thing to grab when your building is on fire, but a copy of Marcus Aurelius’ Meditations is a great distraction from the 80-degree night while you’re waiting to be cleared to be let back in.
