Max Brooks - The zombie survival guide - complete protection from the living dead

C. Memories

A modern conceit is that a zombie retains the knowledge of its former life. We hear stories of the dead returning to their places of residence or work, operating familiar machinery, or even showing acts of mercy to loved ones. In truth, not a shred of proof exists to support this wishful thinking. Zombies could not possibly retain memories of their former lives in either the conscious or subconscious mind, because neither exist! A ghoul will not be distracted by the family pet, living relatives, familiar surroundings, etc. No matter who a person was in his former life, that person is gone, replaced by a mindless automaton with no instinct other than for feeding. This begs the question: Why do zombies prefer urban areas to the countryside? First, the undead do not prefer cities, but simply remain where they are reanimated. Second, the main reason zombies tend to stay in cities instead of fanning out into the countryside is because an urban zone holds the highest concentration of prey.

D. Physical Needs

Other than hunger (discussed later), the dead have shown none of the physical wants or needs expressed in mortal life. Zombies have never been observed to sleep or rest under any circumstances. They have not reacted to extreme heat or cold. In harsh weather, they have never sought shelter. Even something as simple as thirst is unknown to the living dead. Defying all laws of science, Solanum has created what could be described as a completely self-sufficient organism.

E. Communication

Zombies have no language skills. Although their vocal cords are capable of speech, their brain is not. The only vocal ability appears to be a deep-throated moan. This moan is released when zombies identify prey. The sound will remain low and steady until physical contact is made. It will then shift in tone and volume as the zombie commences its attack. This eerie sound, so typically associated with the walking dead, serves as a rallying cry for other zombies and, as has been recently discovered, is a potent psychological weapon. (See “On the Defense.”)

F. Social Dynamics

Theories have always proliferated that the undead function as a collective force, from an army controlled by Satan to an insect-like pheromone-driven hive to the most recent notion that they achieve group consensus by telepathy. The truth is that zombies have no social organization to speak of. There is no hierarchy, no chain of command, no drive toward any type of collectivization. A horde of the undead, regardless of size, regardless of appearance, is simply a mass of individuals. If several hundred ghouls converge on a victim’s location, it is because each one is drawn by its own instinct. Zombies appear to be unaware of one another. Individuals have never been observed to react to the sight of one another at any range. This goes back to the question of sense: How does a zombie distinguish between one of its own and a human or other prey at the same range? The answer has yet to be found. Zombies do avoid one another in the same way they avoid inanimate objects. When they bump into one another, they make no attempt to connect or communicate. Zombies feasting on the same corpse will tug repeatedly on the meat in question rather than shove a competitor out of the way. The only suggestion of communal effort is seen in notorious swarm attacks: the moan of a ghoul calling others within earshot. Once they hear the wail, other walking dead will almost always converge on its source. An early study theorized that this was a deliberate act, that a scout used its moan to signal the others to attack. However, we now know that it happens purely by accident. The ghoul that moans at the detection of prey does so as an instinctive reaction, not as an alert.

G. Hunting

Zombies are migratory organisms, with no regard for territory or concept of home. They will travel miles and perhaps, given time, cross continents in their search for food. Their hunting pattern is random. Ghouls will feed at night and during the day. They will stumble through an area rather than deliberately searching it. Certain zones or structures will not be singled out as more likely to contain prey. For example, some have been known to search farmhouses and other rural structures while others in the same group have moved by without even a glance. Urban zones take more time to explore, which is why the undead remain longer in these areas, but no building will take precedence over another. Zombies appear to be totally unaware of their surroundings. They do not, for example, move their eyes in a way that would take in the information of a new setting. Shuffling silently, with a thousand-yard stare, they will wander aimlessly, regardless of location, until prey is detected. As discussed earlier, the undead possess an uncanny ability to home in on a victim’s precise location. Once contact is made, the previously silent, oblivious automaton transforms into something more closely related to a guided missile. The head turns immediately in the direction of its victim. The jaw drops, lips retract, and, from the depths of its diaphragm, comes the moan. Once contact is made, zombies cannot be distracted by any means. They will continue to pursue their prey, stopping only if they lose contact, make a successful kill, or are destroyed.

H. Motivation

Why do the undead prey upon the living? If it has been proven that human flesh serves no nutritional purpose, why does their instinct drive them to murder? The truth eludes us. Modern science, combined with historical data, has shown that living humans are not the only delights on the undead menu. Rescue teams entering an infested area have consistently reported them stripped of all life. Any creatures, no matter what their size or species, will be consumed by an attacking zombie. Human flesh, however, will always be preferable to other life forms. One experiment presented a captured specimen with two identical cubes of meat: one human, one animal. The zombie repeatedly chose the human. Reasons for this are still unknown. What can be confirmed, beyond any shadow of doubt, is that instinct brought on by Solanum drives the undead to kill and devour any living creature they discover. There appear to be no exceptions.

I. Killing the Dead

While destroying a zombie may be simple, it is far from easy. As we have seen, zombies require none of the physiological functions that humans need to survive. Destruction or severe damage of the circulatory, digestive, or respiratory system would do nothing to a member of the walking dead, as these functions no longer support the brain. Simply put, there are thousands of ways to kill a human—and only one to kill a zombie. The brain must be obliterated, by any means possible.

J. Disposal

Studies have shown that Solanum can still inhabit the body of a terminated zombie for up to forty-eight hours. Exercise extreme care when disposing of undead corpses. The head in particular possesses the most serious hazard, given its concentration of the virus. Never handle an undead corpse without protective clothing. Treat it as you would any toxic, highly lethal material. Cremation is the safest, most effective way of disposal. Despite rumors that a pile of burning corpses will spread Solanum in a cloud of smoking plague, common sense would dictate that any virus is unable to survive intense heat, to say nothing of an open flame.

K. Domestication?

To reiterate, the zombie brain has proved, so far, to be tamper-proof. Experiments ranging from chemicals to surgery to electromagnetic waves have yielded negative results. Behavioral modification therapy and other such attempts to train the living dead like some kind of pack animal have similarly met with failure. Again, the machine cannot be rewired. It will exist as is, or it will not exist at all.
