There are so many possible scenarios …
Which is why it’s important that we each focus on the very basic preparation things first, then start preparing for the various scenarios that COULD happen. And then not get too overly focused (paranoid?) about any one scenario or another, to where life isn’t still worth living here and now, even in the midst of preparing for much worse. For most of us, life is still good, overall, and needs (and deserves) to be enjoyed.
