There are all kinds of emergencies out there that we can prepare for. Take a zombie apocalypse for example. That’s right, I said z-o-m-b-i-e a-p-o-c-a-l-y-p-s-e.

The Zombie Survival Guide identifies the cause of zombies as a virus called solanum. Other zombie origins shown in films include radiation from a destroyed NASA Venus probe (as in Night of the Living Dead), as well as mutations of existing conditions such as prions
