6 curious defects of the human body
Much is used to the claims that the human body is perfectly designed, that our spice supports it all or that it adapts to all physical and psychic demands, to changing times and to the varying rhythms of life that society has not submitted to.
In fact, in part it is true that we have proven to be a very resistant animal species, capable of spreading all over the planet and living in the harshest situations. But nevertheless, there are also defects of the human body.
Our physical condition presents elements of weakness that surely we all do not know (sweat, intense body odors) and that we take as something "natural". Moreover, we are at a time where medicines, tissues and furniture are constantly being developed that do not harm our body.

The defects of the human body
Some expert biologists and researchers in evolutionary biology, expressly demonstrate that the human body has more failures than you would imagine. Some reactions of the human body highlight those deficiencies, mechanisms that are precisely activated to regulate physical or psychic alterations.
In this article we will review some of these most outstanding imperfections of the human body and explain what they are.
1. Sweat a lot
To make a good explanation, we will compare ourselves with our sister species, mammals, since they also possess the sweat glands to regulate the temperature of their body, but they have less quantity that makes them less vulnerable in different situations.
The human body, on the other hand, sweats excessively and that makes it dehydrate with extreme ease , without explicit need to do a lot of sport. An example is when we sweat because of nerves or anxiety. The brain emits exaggerated signals of tension that causes the glands to fire.
2. The eyelids
Here we find another of the great defects of the human body and its design, especially in a crucial member for our existence. It's about the eyelids . That fleshy part that covers the eyes to protect them from dryness, microbes and other harmful elements in sight, is partly responsible for several vision problems.
It turns out that our eyelids are as fragile as the skin of an apple. Because they are so fine, they do not adequately or effectively protect our eyes, as they do with other living beings such as the hippopotamus or the crocodile.

3. The appendix
The appendix is a part of the large intestine that is located at the junction of this with the thin. Although in some animal species it does have a function, such as marsupials like the koala, in humans this part of the digestive system only serves one thing: to become infected. This has caused the presence of this human body failure it has cost the lives of many people .
4. On the skin ...
The skin is another one of the great defects of the human body, if not the one that harmed more is. According to pharmaceutical studies, 75 percent of the pathologies of the human body are suffered in the skin . Psoriasis, irritations, burns, cuts or acne, are usually caused by the delicacy of the thin layer that protects our interior.
A derivative of these problems is the little fat that it contains, as well as the fine texture that composes it. If we do not resort to sunscreens in summer, to moisturizers in winter, and to pills against some infections, the human body would be unable to solve them. This is, perhaps, a consequence of the use of clothing over hundreds of thousands of years.
5. Autoimmune diseases
All the autoimmune diseases characteristic of our spice are in a certain way a failure of the human body, given that they exist for genetic imperfections related to the functioning of cells They should take care of our protection.
6. The mode of delivery
In our species many deaths occur due to childbirth, and until a few decades ago these were even more frequent. This is the result of bipedalism, since by adapting to walk on the legs, the woman's pelvis narrowed , making the conduit through which narrow babies should pass.
The human body and technology
The opposite of what has happened, happens and will happen within the animal kingdom, the human body and our physical condition does not seek perfection, evolution, more if adaptation. The reptiles, the apes, the birds or the felines, have been developing a biology that surpassed its predecessor, fact that has turned them into born survivors.
On the other hand, the human being it does not have as much need to evolve biologically to survive , but survives through the manipulation of the environment and the creation of technology. It is adapted with accessories such as clothing, natural materials that surround us and the social activity that humanity develops. But for physical purposes, we can do little.
The technology will take care of the rest. She will be the one who replaces the deficiencies of the human body, perfect it through nanotechnology and robotics, as well as the substitution of human organs for artificial ones. Vision microchips or bionic prostheses (arms, hands) are now a reality.
