I don't know if the CDC thinks Nostradamus is correct in predicting a Zombie Apocalypse in 2021 so they're just being cautious or what!
It started making headlines a couple of days ago that the CDC has updated their Zombie Prepardness page. It's kind of strange that they even have a page for that. The page was created in 2011, according to TMZ. You might be thinking to yourself, what is the updated page all about, well most of it follows their, "Get a Kit. Make a Plan. Be Prepared." The tips are just like a basic earthquake or tornado prepardness plan like having an emergency stash at home of food, water and first aid supplies to last at least 3 days. It also has tips on how you can use supplies to treat basic cuts and lacerations.
