I'm probably a very bad prepper. My plans are to prepare for the things that are most likely to happen & actually affect me. Those include but are not limited to blizzards, tornados, power outages, job loss/personal economic issues and recessions. I don't much plan for "black swan" events, ie things that are possible and certainly do occur on long enough time scales but are unlikely in any given year/generation/lifetime. Those include but aren't limited to civil war, supervolcano, giant asteroid, full scale nuclear exchange, super-powered EMP, etc. The black swans are extremely rare so the odds of them occurring in my lifetime are relatively low, and also so devastating that no preparation on my part will significantly improve my odds for survival.
