The Centers for Disease Control and Prevention has created a Zombie Apocalypse Plan. It's fairly well thought out and presented. It's important to be prepared for just about anything. Zombie Apocalypse preparedness is just another step in ensuring the safety and survival of the living in the event that the Mayans were off on their calendar and the Zombies rise to eat all of our brains.
If nothing else, it is a good laugh, and laughter is the best medicine. Thank you, CDC, for looking out for the well being of all, in many ways.
