For different reasons, my DW and I are on the same page.
She lost much of her family in the holocaust; her Mom "went to the forest" (partisans) and survived. That and growing up in the USSR (with unpredictable supplies of anything and everything) produced a strong tendency to "stock up" and not throw anything out that "we might need."

For me, I've been in enough situations where everything was OK, then it seriously wasn't, and I got through it mostly by dumb luck that one day I really woke up and started to get ready. And that includes bugging out, which I had to do in Washington DC in 1968 due to the riots that caused my university to totally shut down-- could not stay in Dorm and the cafeteria closed. We always consider having to leave a possibility.
