Terrible! It can manipulate your brain

As we all know, there are other creatures with different forms on the earth besides human beings. We share all kinds of resources on the earth and maintain the ecosystem on which we live. Among all creatures, human beings have always played the role of "boss" because of their leading intelligence. However, in fact, a group of seemingly the weakest and most inconspicuous creatures have been in a secret corner, controlling various creatures that crush them on the physical level. They are parasites.As the name implies, a parasite is an organism that lives on the surface or body of another organism and receives nutrients from the host to maintain its life.Parasites account for about 40% of the known animal species. Some of them are visible "worms" and some are invisible bacteria, viruses and fungi. Although this group of creatures has a simple mind and underdeveloped limbs, they can drive all kinds of big guys to achieve their goals.You may think that these hosts are low level creatures with relatively simple structures. If humans are complex, they will not be so easy to control. But in fact, everyone's preference, personality and body shape are not determined by themselves. In other words, it is affected by parasites that you can become what you are now. 02 There are more than 1000 species of microorganisms in parasites and human body (including body surface), and the number is up to 100 trillion, about 10 times the number of human cells. The sum of genetic material of these microorganisms is about 150 times of our own genetic material.The most direct way to affect human beings is to cause disease.For example, dracunculiasis medina will release an acid substance, which will make human skin produce blisters with burning sensation. Once the victim immerses the inflamed part in water, the female will take the opportunity to lay eggs and parasitize in the water flea, waiting for the next parasitic cycle to open.Rabies virus will affect the central nervous system responsible for aggression, sex, hunger, thirst and other functions of the human body, making patients have strange behavior.The way that some parasites affect human beings is difficult for us to directly perceive. For example, malaria parasites may magnify your body odor, or induce you to produce an odor that attracts mosquitoes.
