I totally dig the whole Survivalism subculture and such. But some people take it a bit too far. I know that personally, I could prolly outfit my home and get supplies to deal with anything from a snow storm to a zombie outbreak. But the thing is, that even if you are fully prepared, you will never be in a 100% situation to perfectly use and employ all those skills and tools. More or less the whole 'Survivalism' subculture has grown because of FEAR. As it is well known, the more advanced a society is, the more to Fear there is. In the past we only had to fear things like tornado's destroying homes or fires spreading across our crops, so naturally we would be prepared for such events. But now, we have a multitude of things to fear and try and prepare for. And the odds of these several thousand, maybe millions of things happening are incredibly low.
