I'm just a bit strange. Always kind of done it, even since I was a kid. Just didn't know there was a name for it.
Plus I'm lazy, so used to go shopping once a month, normally filling 2 or 3 trolleys. Nice to have full cupboards. Now I seem to spend every day, and every penny, in a supermarket buying more and more food. I've got a whole room full of it, it's not the kitchen either
So I've always been what people would call "strange" - always had knives and other assorted weapons. I've got a problem with throwing things away, I have to keep them "just in case". Now I've got little 'un, and the wife is on board, we take it very seriously. I'm currently trying to bulk up my first aid / trauma kits and some off-grid power.
