RE: survival question.
Good question. Not an every day thing we think about, but probably should. I never step into the woods without my cell phone. Two things will make me get out of the tree and walk back to the truck - forgetting my safety belt or my cell phone. If I fell in the hole on the way back to the truck to get my cell phone I forgot, well, I' d be screwed. Cut clothes apart, grab some sticks, and get to work on stopping the bleeding. First and foremost, pray.
