It is human nature to approach preparedness according to gaps that we see in our plans. Most of us make checklists (see List of Lists), have 72 hour bags (BOB), and cover the three B’s (Beans, Bullets, and Band-Aids). We rotate food and water, learn new skills, and do anything we can to bridge the gap between our perceived lack of preparedness and what we consider as “sufficiently prepared”. We may get so caught up in building bunkers and buying bullets that we operate in an “out of sight, out of mind” mode. Sure, we should prepare for four-legged and two-legged predators, but what about our unseen enemies?
