Our efforts toward a self sustainability lifestyle have continued with more recent efforts in two areas. First, becoming our own first responder for medical, fire and security emergencies and secondly, assuring we have no single point system failures. For example, we've developed redundant medical kits to address most emergencies. One kit remains in the house while a second one is placed in which ever vehicle we're using. We've gone through all our support systems (electrical, water, heating, communications, etc) and identified the potential for single point failures and addressed these by either installing redundant systems or by procured spares to fix these systems.
Like a lot of things these days, terms have changed. Today's "preppers" years ago were known as retreaters, bushcrafters, survivalists, homesteaders and even realists. While the focus may be different, most folks were addressing some level of a self sustainabiity lifestyle, which was good!
