Here is the best advice ANYONE WILL EVER GIVE YOU: The best time to prepare for the worst is during peacetime or no panic. To prepare during a crisis is REALLY dumb.
If your plan is to only prepare for a crisis when a crisis is happening you might as well just dig your own grave.
That is my only point.

Now is the smart time to plan and prepare for a 'real' crisis. Not when it is happening. Again, if that's your plan, don't count on surviving any crisis in general.
NOTHING IS IMMEDIATELY A THREAT. HOWEVER YOU DO NOT WANT TO PREP FOR A CRISIS DURING A CRISIS.
