tracts have exploded from within.
J. Respiration
The lungs of the undead continue to function in that they draw air into and expel it from the body. This function accounts for a zombie’s signature moan. What the lungs and body chemistry fail to accomplish, however, is to extract oxygen and remove carbon dioxide. Given that Solanum obviates the need for both of these functions, the entire human respiratory system is obsolete in the body of a ghoul. This explains how the living dead can “walk underwater” or survive in environments lethal to humans. Their brains, as noted earlier, are oxygen-independent.
K. Circulation
It would be inaccurate to say that zombies have no heart. It wouldnot be inaccurate, however, to say that they find no use for it. The circulatory system of the undead is little more than a network of useless tubes filled with congealed blood. The same applies to the lymphatic system as well as all other bodily fluids. Although this mutation would appear to give the undead one more advantage over humanity, it has actually proved to be a godsend. The lack of fluid mass prevents easy transmission of the virus. Were this not true, hand-to-hand combat would be nearly impossible, as the defending human would almost certainly be splattered with blood and/or other fluids.
L. Reproduction
Zombies are sterile creatures. Their sexual organs are necrotic and impotent. Attempts have been made to fertilize zombie eggs with human sperm and vice versa. None has been successful. The undead have also shown no signs of sexual desire, either for their own species or for the living. Until research can prove otherwise, humanity’s greatest fear—the dead reproducing the dead—is a comforting impossibility.
M. Strength
Ghouls possess the same brute force as the living. What power can be exerted depends greatly on the individual zombie. What muscle mass a person has in life would be all he possesses in death. Unlike a living body, adrenal glands have not been known to function in the dead, denying zombies the temporary burst of power we humans enjoy. The one solid advantage the living dead do possess is amazing stamina. Imagine working out, or any other act of physical exertion. Chances are that pain and exhaustion will dictate your limits. These factors do not apply to the dead. They will continue an act, with the same dynamic energy, until the muscles supporting it literally disintegrate. While this makes for progressively weaker ghouls, it allows for an all-powerful first attack. Many barricades that would have exhausted three or even four physically fit humans have fallen to a single determined zombie.
N. Speed
The “walking” dead tend to move at a slouch or limp. Even without injuries or advanced decomposition, their lack of coordination makes for an unsteady stride. Speed is mainly determined by leg length. Taller ghouls have longer strides than their shorter counterparts. Zombies appear to be incapable of running. The fastest have been observed to move at a rate of barely one step per 1.5 seconds. Again, as with strength, the dead’s advantage over the living is their tirelessness. Humans who believe they have outrun their undead pursuers might do well to remember the story of the tortoise and the hare, adding, of course, that in this instance the hare stands a good chance of being eaten alive.
O. Agility
The average living human possesses a dexterity level 90 percent greater than the strongest ghoul. Some of this comes from the general stiffness of necrotic muscle tissue (hence their awkward stride). The rest is due to their primitive brain functions. Zombies have little hand-eye coordination, one of their greatest weaknesses. No one has ever observed a zombie jumping, either from one spot to another or simply up and down. Balancing on a narrow surface is similarly beyond their ability. Swimming is also a skill reserved for the living. The theory has been put forth that, if an undead corpse were to be
