Preparations for the worst

I've watched today some interesting videos on YouTube concerning on preparation for the exceptional times/moments such as war.
I don't know how many people have prepared for this kind of random events - especially in Europe. I know that there are some folks (Mormons) in Utah that are storing food, toilet paper, shampoo, soap, water etc.

This kind of preparation might be wise in two senses: you always need those items and the prices of them tend to raise from year to year so you can see it as an investment to hedge your future. Secondly, if the worst really happens you don't need to regret that you have been prepared well for it.

Thus, I thought to start stockpiling food... For me personally this is good also because I usually have to throw away food since I've been not able to eat all my food supplies before their expiring dates - so can goods are just perfect for a person like me anyway.
So, my plan is to start buying cans of crushed pineapples, peaches, bags of rice, wheat and rye, spices, toilet papers (usually you get a discount if you buy a lot at one time), soaps and shampoos.

The idea of storing food and preparing for the worst scenario is very Biblical. In the first books of the Bible there is a story of Joseph who stored wheat during the seven good years for the upcoming seven bad years.
