People underestimate the logistics of actually living in a zombie apocalypse

Okay, seriously. It's fun to think that we're going to be the badass hardened survivors who'll adapt to the zombie apocalypse and thrive, it's a nice power fantasy, but let's actually think about some of the logistics of it.

- Medicine: Whatever medicine you have already is not going to last long. And it'll only keep getting harder and harder to come across as it keeps getting scavenged. Eventually you'll get a cut on your thumb or something and get an infection with nothing to treat it with. Boom, you're fucking dead.

- Food: Canned foods are not sustainable for the long run. "I'll just start farming!!" I hear you say, but no, you fucking won't. Farming is hard as shit and takes a lot of trial and error, and even experienced farmers sometimes have their crops fail. All it takes is an unlucky season and your city-boy asses will starve. Boom, you're fucking dead.

- Practical knowledge: Things like knowing how to fix your vehicle if it breaks down, how to operate a generator, how to do maintenance on your shelter, etc... "I'll just go to a library and take all the useful books, no one ever thought of that!!" no you fucking dimwit. I've already seen your brilliant idea posted dozens of times before by others. By the time you reach the library, all the practical books will be already scraped clean by people way faster than you.

- Environmental factors: People rarely think about nature. If you're in the far northern hemisphere, there won't be any heaters to prevent you from freezing to death, and simply wearing a lot of clothing isn't going to be enough (unless you know how to make insulated houses, which you probably don't). There are buildings you can hide in, but it'll only take so long before they begin to break down and let nature get your ass. Also, if you happen to live in the east coast, there won't be any emergency services to save your ass in case of a hurricane (and apply this for other natural disasters). Boom, you're fucking dead.

So yeah. I haven't even scratched the surface of potential run-ending factors.
