Preparing for a Food Shortage?

The question that looms over most prepers is when to start using their reserves. We don't know what could happen, it could be a slow decay where food is scarce but intermittently available. The idea that we may need to be prepared for anything more than that comes with major psychological implications.

It's like a global roshak test. But some of us will be right.
