Paranoia is a sad sad thing. I have a friend that is of that gild. He could survive off the food in his basement for years. He is combat trained/combat proven yet the thing he will die from before he ever has the last laugh over a terrorist takeover is a 2 dollar cheeseburger heart attack. I'm sure the stress of building a fallout shelter attributed.
I have faith that when the world ends... I under no circumstances want to be here.
