A personal opinion...

For many of us I think skills like these will turn out to be THE survival skills if/when truly large scale disasters strike. The "Grizzly Adams" approach of living in the woods appeals to our macho psyche, but the reality is that throughout human history man has never faired well alone.... never.

We are a social animal and our god-given gifts are all tuned towards succeeding in a cooperative way. We don't see/smell/hear/run/leap etc as other animals. But we have the most advanced brains and communications capabilities.

Food for thought,
