A classic example of “efficiency is the deadly enemy of robustness.”
IOW, the more efficient your system the less capable it is of handling bumps. The free market encourages constant striving towards the ideal of 100% efficiency.
But of course as we get closer to the ideal we simultaneously become less capable of dealing with interruptions to the free flow of stuff.
Department and discount stores used to have large warehouses around the country filled with stuff ready to be shipped out to the stores. It acted as reserve capacity.
Walmart set the standard by becoming more efficient. Their storage is essentially all in trucks on the road between the supplier and the store. Very few warehouses relative to the volume they do.
Therefore they will run completely out quickly if the flow is interrupted.
Right there is a huge part of why so many freak out during an emergency. IOW, on the average day they would have two cans of beans and call it good. Let's say a quarter of them don't have a manual can opener. Then of those 75% who have the means and sense to open a can, half of them would let their kids die on the spot rather than serve them cold beans out of the can.
Question. In general, with canned foods stored at room temperature and in good condition, how long can one safely consume the food past the expiration date? Obviously, a seriously dented can or an expanded can would indicate the food is probably unsafe, are there any other signs for canned foods that indicate the food is unsafe for consumption?
In fact if it is all about food just get as much canned beef, cereals and cheap pasta as you can. You won’t ever store enough wather, so invest into filter system and chemicals (potassium parmanganate)to make any available water safe.
