Nothing out of the ordinary.
Covid was good basic training for a global catastrophe.
IMO all we can do is take the same basic precautions and continue with the same basic preparations that apply in most situations.
I try to keep the car tank above half, keep a bit of cash on hand, important documents are ready to grab ‘n’ go, a couple weeks food on hand, etc…
A solar charger for my phone might be a good investment that would be useful in most emergencies.
My biggest concern with all of this turmoil around the world is a serious and possibly long term disruption or correction in the financial markets that could impact our future retirement income.
