The concept of a zombie apocalypse is bullshit.

If zombies were a real threat, they would have spread globally long before anyone even knew what was going on. Why would every infected person wait for the world to figure out that they are dead and contagious? Why wouldn’t they infect other people as soon as they became infected? And if an infected person dies in public, every single person that sees it will be infected immediately. This is not a remote forest island type of situation, this is the middle of a city. The first signs of zombie infections would be the moment the infected people first get sick. The information would spread faster than the disease.
