...If this theory is correct, is there a way to teach urban survival skills?...So what do you guys think? Teachable skills or not?
Yes, urban survival skills are teachable. I don't think the method for learning urban survival skills is all that much different than learning nature survival skills. For each, a limited amount of knowledge can be obtained from reading a computer screen or from listening to a lecture. Both urban survival and nature survival require a substantial amount of "street knowledge" that can only be obtaining from just doing it.
