Do you have doom related hobbies?

MMA: THAT will come in as handy as anything... it is also something that might save your ass before the apocalypse. Knowing how to put someone to sleep with your bare hands is priceless- it is also a great equalizer- a woman skilled at MMA can defeat many/most men who have no working understanding of the concepts.

Locksport: being able to access locked areas/rooms/homes without making a bunch of noise might be a really good thing to know.

Basic outdoor survival: minimalist backpacking will prepare you psychologically for living with little to nothing in unfamiliar environments- there are many schools teaching outdoor survival these days.

Basic firearms knowledge and marksmanship: Many people own firearms. Some feel more is better, yet they have poor marksmanship skills and understand nothing about weapons care and maintenance.

Psychology: knowing how people will react (sometimes before even they do) is priceless... understanding how to barter... and what to look for in a person who might or might not be trustworthy or "sane" will come in extremely useful.

YIKES on your poison cooking. Ehhh, mental note not to get on your bad side!
