Are there zombies in the world?
10. Humidity is hell.
The extreme weather of the earth will make zombies pay various prices. High temperature and high humidity provide an extremely suitable environment for the growth of bacteria and insects, and the enzymes released by these bacteria and insects can decompose anything. The dry and hot climate in the desert will exhaust the zombie's body in a few hours. The cold winter will make the bones of zombies "brittle" more fragile.
Not to mention ultraviolet rays in the sun, hurricanes, heavy rains and hail, or heavy snow. Of course, these unpredictable weather may also be the reason why many zombies choose to stay in relatively safe basements, dungeons and abandoned prisons.
9. They are special cases of dynamic "failure"
We are all dynamic animals, and our movements can only be completed through the connection of muscles, tendons, bones and other elements. When there is a problem in a certain part of the human body system, we may be inconvenient to move or even unable to move at all. It is really puzzling that modern zombies can move even when their flesh and bones are crumbling. However, when many zombies stumble in front of them (sometimes at amazing speed), we seem to forget that it is impossible to complete these actions only by their rotten, fragmented muscles and broken bones, and we have not even considered their lack of brains.
8. Lack of immune system
Viruses have been our most dangerous natural enemies since the appearance of human beings. There are many white blood cells in our immune system, which destroy the infection that enters our body and keep us alive for at least a while. People with defective immune systems are constantly troubled by various problems. This is also the problem of zombies, because zombies have no immune system to protect themselves. Zombies are exposed to the air, so they become the best breeding ground for countless bacteria, fungi and viruses, which will shorten their life span and these bacteria, fungi and viruses will devour them from the inside out. However, since they are zombies, this may be a good thing.
7. Lack of metabolism
We humans eat food to convert chemical energy into energy that can maintain our activities from breathing to reproduction, and it is also our metabolism that maintains these processes. Metabolism plays an important role in all the chemical reactions that take place in our body. Theoretically, zombies eat people's brains because they also need some food that can keep them active all the time, but there is a problem here: zombies are not really alive.
As a member of the undead society, they actually lack various metabolic abilities. Zombies have no ability to metabolize. Even if they can conjure up some energy when chewing delicious brains, their stomachs (if they have stomachs) can't provide these undead or inanimate things with a chemical that can convert nutrients into energy.
6. Dogs eat zombies
If you are a zombie, when the dawn comes, you will be very afraid of predators such as hyenas, wolves, bears, foxes and ferocious wild dogs. They are fast and sometimes very fierce. When they are very hungry, they will become rude and attack healthy humans.
Resurrected dead bodies are essentially walking meat bags, so how do these animals react to them in vision and smell? After the zombie invasion, the balance of the ecosystem will be broken. Like humans, these animals will do whatever it takes to find food, and the attacks of other animals will not be restricted by top carnivores. If given the chance, smaller animals such as rats, raccoons and opossums will also be happy to eat undead things, such as a zombie lying in a mud pond waiting for the end of his pain, because his hand is broken and his leg is gone.
5. sensory insufficiency
Vision, hearing, touch, taste and smell are all essential to our survival. Without these five senses, we would wander aimlessly on the earth, and in a short time, we would eat poisonous plants and touch every passing door frame. There is no doubt that our toes will touch every coffee table. Because zombies are not a complete individual, it is difficult for us to understand how they complete a series of important actions when hunting delicious brains. When they start to rot, the soft tissue around their eyes will decompose and fall off first, and zombies can only blindly catch the person who unfortunately walks into their black claws. In most cases, healthy people can completely avoid contact with these monsters.
This is not bird flu.
Zombies take hostages for a long time to finish biting. It is very challenging for zombies who lack arms and legs to subdue frightened prey. Biting is a process that takes a lot of time and energy. Of course, time and energy are indeed extravagant for rotting zombies. To bite a person, you need to be in close contact with the victim. When the survivors are on alert and difficult to be found, those cold and slow-moving zombies will get into trouble and have to compromise with their warm-blooded relatives-humans.
Time heals all wounds, but zombies don't.
Cuts give dust and bacteria room to crawl and give them a chance to invade your internal organs. However, most people's wounds will eventually heal after sanitary treatment, but the healing process may take longer and sometimes produce long-term side effects. But whether it is minor or serious, the wounds of zombies are permanent. Imagine that if you don't handle it, the small wound scratched by paper will not heal itself, and even deepen and expand with time. Because human body and tissue are always splitting, bones will be exposed, and finally dead skin will fall off.
A small scratch will make the zombie's skin fall off, and it will take effect immediately. Burned skin will condense into sticky and dirty things. This series of decomposition may be the best way-after all, no one wants to be a zombie forever.
2. Zombies may be unable to defecate
The full function of zombie bodies is not clear. Maybe there are many gaps between their mouths and some parts of the digestive system. It may also be that these gaps in the digestive line help zombies absorb some nutrients from food. Of course, because zombies don't have many physiological functions, it is very likely that the human brain they eat has entered a dead end (pun), that is, the junction of the end of esophagus and the beginning of stomach. As zombies continue to enjoy the human brain meal, these indigestible sticky things can only ferment and bubble in the stomach, and finally burst the stomach wall of zombies.
No dentist serves the dead.
Zombies generally can't brush their teeth twice a day like people. Their gums rot, their enamel breaks and becomes smaller, their teeth will be damaged, there will be dirt residue, and eventually they will fall off. Just say it, it's really empty. However, the teeth of zombies are probably the only sharp parts of zombies. If you really accidentally fall into the death clutches of zombies, their teeth are formidable weapons even if they are fragmented. Of course, this is impossible! After all, so far, germ warfare, radiation leakage and fungal infection have not brought the world to destruction, and zombies are even more empty talk.
