Completely true, although now that I've gone through the fun little exersize, I'm sure some of the concepts and tools can be applied to our everyday carry for more mundane emergencies.

If you magnetize just about anything you could use as a compass, you're never with out one, even if you forget or lose your PSK along with the rest of your kit (as unlikely as that happening might be).

If you travel, lots of people you might want to curry favor with in foriegn (especially third world) countries might be swayed with a simple pack of American cigarettes. Carrying cigarettes when travelling even if you don't smoke might save you a lot of trouble.

Just another way of looking for solutions to the problems we're preparing for.
