“Most natural disasters will last for less than 2 weeks, so if we all just could “survive” on our own for that amount of time, we would all be ok.”
One helluva lot more clarity/detail is required on that first fragment of the sentence. Therein lies the big unknown. That is when most chaos will set the stage for anything that occurs later, if you survive.
...I was addressing natural disasters.
Man made disasters are another thing...they can last a lifetime...and they are the ones that the "preppers" are addressing IMO.
I am too old and too tired and too lazy, I suppose, to prep for what a lot of people anticipate....which is a total breakdown of society.
I will have to admit that I have not been successful in convincing my adult children the urgency of being prepared for chaos and what will happen when hungry, low info people come looking for food....but that is my failure.
