If we go back with our thoughts to 1999 and remember the worry about Y2K, it may help us to balance our thoughts and emotions.

In every culture there are 'signs' or 'prophecies' ..etc. and older people have seen some come and go without much materializing. So, I would say : we should keep prepping as we normally do. Not a bad idea to step up the pace if it makes us less stressed. But really, there is just not that much more any of us can do about a real-life big-bang type of SHTF.
