Most countries have some kind of “disaster preparedness” suggestions, be they for earthquakes, floods, tornados, WMDs, etc. A lot of these suggestions overlap: have a stock of food, know where important documents are, think about where you’d shelter, etc.

There will probably not be an extinction-level event. But at some point in your life you may experience an emergency where you need a stock of food, to know where your documents are, to have a place to shelter, etc. So maybe it’d help you out to make plans for what you’d do in case of a general emergency/disaster.

Here are a couple useful documents that were made in the US:
