I have always wondered that if there is such a small percentage of humans alive during a zombie apocalypse and so many zombies on the hunt for human brains then wouldn't be easier just to hold out in a bunker with enough food for a month till the undead starve to death? Maybe some of you have read more materials or watched enough movies to be able to give me an explanation. I just would like to know if they eat anything else like animals brains, each other, or if they actually eat the entire humans like depicted in some movies and not just the brain? Just give me some examples from movies, books, ect.
