My grandmother escaped from what became East Germany by the skin of her teeth; everyone else in her family was murdered in the Holocaust. My grandfather on that side had a similar experience escaping Russia (although obviously it wasn't the Nazis murdering his family).

I didn't know to call it a "Bug Out Bag" until much later in life but I've had one since I was about ten years old. Including things like cash and passport.

However to bws48's original questions, I've never felt all that insecure or unaccepted in larger society due to my heritage.

The other component of it for me relates to my screen name. Ever since I can remember, odd and awful things happen around me. Not (usually) because of me, but around me nevertheless. So I learned how to handle crises out of self-defense. Preparing for them now is second nature.
