I would like to take this opportunity to discuss the Second Law. There are many theories as to why a Zombie will not eat another Zombie.

Those that believe that a virus is responsible for reanimation tend to fall into two different camps. One theory is that an infected organism can sense the viral presence in another organism. Perhaps due to territorial respect or maybe because the virus simply knows it can not hope to displace the original virus, a reanimated corpse will not attack another such corpse. The second largely accepted theory is that the Zombie can differentiate between decaying and non-decaying tissue. It's like when we see a really moldy piece of bread and know that no matter how much peanut butter we use, it's not going to make tasty sandwich.

While these are the two main theories, there are many other speculations regarding the Second Law. Some believe that Zombies just don't taste as good as living humans. Others believe the smell is enough of a deterrent. (Would you eat something that smelled like that?) Of course there are also the theories involving topics discussed in this thread. The undead might need living tissue to re-energize, or they might need the chemical components of a living, non-infected brain and they just can't get these ingredients from another Zombie.

The reason the Second Law requires further study rests in the hopes that we can reverse it. Sure, some people want to approach the problem by determining what makes a Zombie want to eat Uncle Harry. I say, let's find out what keeps Uncle Harry from eating another Zombie when he joins the ranks of the undead. If we can reverse the Second Law, Zombies will eat each other and the possibility of an undead horde becomes extinct.
