Some people enjoy books about useless fantastical stories like kids going to a school for magic, or some people taking a ring to a mountain or even love triangles between a bloodsucker, a half-dog man and a socially akward teen.
These people will either die, or become zombies. You won't. Because while others are escaping reality, you're preparing for it. Don't even think about it. Buy this. Read it. Study it. Live it. And who knows- Maybe I'll see you on the other side of the zombie apocalypse.
