All women have this fatal flaw

Medical experts have recently suggested that every part of our body, from the eyes, ears, mouth and nose to the heart, appendix and other internal organs, has deficiencies in both appearance and function, which at the very least bring a lot of inconvenience to our lives, and at the worst endanger our health. Interestingly, in terms of body structure alone, many animals are stronger than us humans.

Brain cells will die if they are deprived of oxygen

The brain is not designed to be dangled on high-speed cars, airplanes, and high-speed toys at amusement parks. In addition, once deprived of oxygen, brain cells will die soon. The epaulette shark's brain could survive even without oxygen for an hour.

Cartilage wear is difficult to repair

The knees are under tremendous pressure throughout their lives, and the cartilage wears out, making it difficult to repair itself. Other animals have amazing jumping ability, thanks to their perfectly constructed hind legs, which greatly save energy used for running.

Lack of shock absorption

Our feet are not designed to absorb shock, so the impact of walking is transferred directly to the knees and hips. If a layer of fat or collagen grew on the soles of our feet, our bodies would be more perfect.

Ear hair cells are easily damaged and difficult to regenerate

The hair cells in the human ear canal are essential for hearing, but these cells are easily damaged by noisy sounds, thereby impairing hearing. If only we had the ears of birds, whose hair cells can regenerate automatically.

I always choke when eating because I have too many teeth.

We choke because the mouth is the entrance for both food and air. It would be nice if there was a safety filter in front of the trachea that could intercept food while allowing air to flow unobstructed. Humans only need 20 teeth. Wisdom teeth are basically useless but still "stay" in the mouth.

No self-repair function

The human liver can repair itself, but the heart cannot. Giving the heart the regenerative power of the liver would be a major medical breakthrough. In addition, the heart needs a new type of blood vessel, that is, blood vessels that can grow automatically, so that they can bypass the embolism and continue to perform the function of oxygen supply.

Too narrow field of view

In order for humans to see anything clearly, light needs to pass through a small area in the middle of the retina, which makes humans have a narrower field of vision than other animals. If the human retina had a wider light-receiving surface, it would not only improve night vision, but also allow people to see the football coming from multiple angles when playing football.

The human neck is the most vulnerable part of the body, but it contains a very important nervous system. Once these important nerves are damaged, we will become paralyzed. So the neck should actually evolve to be shorter. Of course, having no neck is best, but then it would be like a gorilla.

A nerve is exposed

A stretch of nerve several centimeters near the elbow is the result of human evolution, but it is exposed to the outside, without adequate protection, and is easily damaged. If it grows on the inside of the elbow, this problem does not exist.

It's useless and I still get inflammation.

The exact function of the appendix is ​​still unclear, but once it becomes inflamed, it can be extremely painful and even life-threatening.
