I'm curious to know...
Do any of you pack your BOBs or kits or whatever with anything that isn't needed for physical survival? Something which comforts you or helps keep your mind and/or morale good? A book, a picture, a game, etc?
From a purely academic point of view it seems silly...but I do it. I don't go anywhere without a cigar, a punch cutter, and a proper lighter. If I'm going to be in a rough survival situation, I want to have something to enjoy while the chips are down.
Now that I'm thinking about it however even these things can be used in survival. The punch cutter could be used to put small holes in things, the lighter is obviously useful, and tobacco is a drawing agent which works great for pulling the toxin out of a bee or wasp sting. You could also use the cigar to transport fire if you had no good way of re-lighting a fire. It burns slow and won't go out easily if you take a puff occasionally.
I guess anything can be a survival item in a pinch.
