Zombies and vampires are all the rage here.
Mock if you want but understanding zombies is the way to understand humans .
I discovered this last year when I read this must read book if you want to understand international politics .
Amazon.com: Theories of International Politics and Zombies (9780691147833): Daniel W. Drezner: Books
Basically it does the same thing as the CDC does (using the example of zombies in applying practical steps to take in emergencies) The author uses the examples of confronting the threat of zombies based on various models of international relations like realists ,neocons ,isolationism ,or those who think that the undead are just misunderstood and should be added to the nations of the UN,to explain the various political theories.
