Let's really look at the facts about zombies, and why no one should have a "zombie survival" plan:
1:
If the brain runs the whole operation and their circulatory system is no longer functioning then their skin will die and start to rot away after a month or so. Once the brain rots they'll lose motor skills and begin to decompose completely. No longer an apocalypse, just smelly, goopy corpses gurgling into the ground.
Zombie apocalypse over in like 3 months tops. I could stop there, but I'll keep going.
2:
No circulatory system, no digestive system. Once they've eaten once, they'll bloat up from the wealth of bacteria in their system, sitting stagnant to reproduce, and decompose from the inside out.
3:
Probably after a week at least half of the zombies would have broken a leg or 2, stepping in holes or twisted an ankle on a street curb then broke it by putting their full weight on it. Crippled zombies aren't a threat.
4:
Carrion eaters. Scavengers. Predators. They exist.
5:
Cataracts. Blind and visually impaired zombies within a few days.
6:
Every time a zombie apocalypse happens in a movie or game, somehow the world's governments and militaries can't systematically kill off staggering corpses. Not too sure why they just jump into the middle of them and shoot haphazardly until they get eaten alive like they never learned simple problem solving. Funnel them in, the end.
I mean, the list goes on and on. What I want to see in things labeled sci-fi is some science with my fiction. Don't feed me straight fiction and through "science" in the name.
