- some fire-starting techniques (haven't had the chance to try them)
- how to build a crystal set radio-- the most high-tech thing it requires is a speaker, and communication is vital
- how to build a generator
- I could probably remember how to build a motor
- how to build a still to purify water with the sun or a fire
- a basic procedure for checking if something is poisonous
- I've practiced archery before (not a lot, but I think I could manage after a while)
- I have some understanding of fermentation so I could probably make alcohol for disinfecting things (I don't drink, and I probably wouldn't start then unless I had way more alcohol than I needed)
- a basic knowledge of Spanish-- if there's anyone else left, chances are some of them will speak it, and again communication is vital
- I do fairly well under pressure
- high tolerance for pain, cold, and noise
- it might sound odd, but I can ride a bike-- motorized transport will probably end quickly and getting around faster than the 5-10 MPH most people can manage on foot (some people have gone as fast as 80 on a bike) could be pretty valuable (especially in areas that aren't conducive to horses, camels, llamas, etc., or don't have any)
- I might know how to make soap, I'm not sure I'm remembering correctly
- possibly most valuable, I'm careful and I've become quite patient, but that doesn't mean I can't be aggressive if the situation calls for it, and I can read, so whatever information is left in books (assuming they're in English or Spanish), I can make use of
