Suppose the walking dead attacked your house. Would you (a) defend yourself; (b) lock the door and dial 911; (c) write a Facebook post blaming the sequester; or (d) negotiate?
If you don't know that the correct answer is (a), you won't survive the zombie apocalypse.
Zombies are everywhere these days. In June, Brad Pitt will star in the film version of Max Brooks's best-selling novel "World War Z." The Westerosi of "Game of Thrones" have to worry about the White Walkers. Harry Potter had to face the Inferi. Even Dr. Gregory House had to battle zombies, although it turned out he was only dreaming.
