Prepping is just insurance. I buy life insurance so my family is taken care of in the unlikely event that I die. I have some stored food, water, etc. in the unlikely event that there's a temporary disruption in my ability to get those things.

I wouldn't say dying is an unlikely event, even if you're young and healthy.

Insurance is you betting you will die and the insurance company betting you will not die. In order for the insurance company to make money, they have to be right more than you.
