The first time I heard the word "prepping" was about 2 years ago when I found a documentary series on YouTube called "Doomsday Preppers." In the series you follow mostly Americans who prepare (prepping) for unexpected events like a nuclear war, a civil war, a society in chaos when it has run out of oil, a global pandemic, and much more. Most families and individuals in the series tend to take this prepping to the extreme and it becomes almost like an obsession. They spend almost all of their money on building underground bunkers, rebuilding military trucks and boats, and they hoard food, water, and firearms. So if something will happen they will be safe.
The keywords is "if." Is it really a good idea to spend all of your money on unexpected events? Personally I believe the answer is no! But you should spend a little time and money on preparing for unexpected events. For example, after the Hurricane Katrina disaster in 2005, everyone could see how difficult it was for even the powerful American government to help a single region in need. What if a disaster happens to an entire country?
I believe a lot of people expect to get help from the government if something happens. "Who cares about prepping, the government will provide money and water!" But that is not always true. For example, here in Sweden we don't have and large storage building with food the government can deliver to people in need. It is up to the individual to survive on his/her own. And the fact is that Sweden will run out of food within 10 days.
What I believe in is prepping "within reasons." The rule that you need to remember is 3-3-3. It says that you will survive 3 minutes without air, 3 days without water, and 3 weeks without food. This is what you should prepare for, and maybe ignore the nuclear wars and pandemics that hardcore preppers prepare for.
This is part 1, but if you can't wait until next part, you should watch a YouTube series called Surviving the Wilderness 2, and learn how difficult it is to survive without being prepared. It's a series where a guy called Bucky Roberts, who is famous for making tutorials on how to write software, tries to survive in the forrests of US. He has no experience and very few tools - and no mobile phone. He almost didn't make it out alive...
