The more I think about basic survival skills the more I think I should take a class in economics.
I'd like to take a class in Logic, have wanted to for years. My old man says he took one back in the day and it really changes how you approach things. And it could be useful from a survival perspective, because often logic becomes blurred... especially if you use a car GPS, apparently.
On the other hand, my employer says I am too logical, but I think thats because I keep winning arguments. Its basically like saying "begone!" but only slightly less annoying.
