Problems that are difficult for scientists to understand

Chapter 2: Secrets of Life (1)
Why are human hands divided into left and right?
As the "spirit of all things", human beings have dexterous hands.However, most people are right-handed, and left-handed people only account for 6%-12% of the world's population. Why is the proportion so disparate?

More than a century ago, people generally believed that left-handedness was an abnormal physiological phenomenon, and even regarded it as a disease.

However, the fact is the opposite. Most of the left-handers in our lives are intelligent and quick-witted people. Especially in some occupations that require imagination and a sense of space, left-handers are often the best talents among them.

Swiss scientist Dr. Irving put forward a new hypothesis.He believes that in ancient times, the probability of human ancestors using left and right hands was equal.It was only later that they ate poisonous plants by mistake. Left-handed people have weak tolerance to plant toxins and it is difficult to continue to survive; while right-handed people, with their tenacious tolerance, finally obtained the ability to survive in nature and passed them down from generation to generation, making people who use the right hand become the vast majority in today's world.Is this really the case?This requires further exploration, comparison and analysis in order to get a satisfactory answer.

Why the heart can be called a smart organ

Recent research suggests that the heart may also be included in the "smart organs".A 72-year-old man in California, USA, lost part of his memory after undergoing heart surgery. He forgot all the people and events of the past 20 years, and even regarded his wife who had been married for 16 years as a stranger.After a housewife in Scotland transplanted the heart of a young man who died unexpectedly due to illness, she also changed from her usual gentle and quiet normal, and became like the young man drinking and making trouble, staying out all night.How to explain these phenomena?Many scholars believe that this is the reason why the heart participates in the work of the brain, and the two together dominate people's thinking activities.

A biochemist in the United States discovered that the heart can produce some special hormones, use them to get in touch with other organs in the body, and even communicate with the brain, "guiding" how other organs can better serve the human body.

Based on the above, some medical scientists believe that the heart is actually a "smart" organ.What exactly is the intelligence of the heart remains to be further studied.

How big is the potential of the human body
In 1984, a middle-aged woman in the United States moved a camphor wood wardrobe down from the third floor during a fire, but once the fire was over, she could not move.The same thing happened on a plane that was forced to land due to a malfunction.At that time, the plane landed in the Arctic region. When the pilot was checking the landing gear of the plane, a white bear suddenly grabbed his shoulder. In desperation, the pilot jumped onto the wing about two meters above the ground, and It's wearing a bulky flight suit!

How can ordinary people become "Hercules"?How much potential is there in the human body?Some scientists believe that mental strength and survival instincts can provide instantaneous boosts to physical strength and endurance, as evidenced by the enormous physical strength displayed by a series of people during dangerous events.

According to statistics, there are 2000 billion cells in the human brain, and when the human brain is excited, only 10%-15% of the cells are working; the human brain can store up to 1000 billion messages, but only one remains in memory. A small portion... So, why do so few reach this limit?Current scientific theories cannot fully explain this problem.

Human Spontaneous Combustion Revealed
In the UK, a 19-year-old girl suddenly burst into flames while dancing with a group of others. People present immediately tried to put out the flames, but failed to save the girl's life.Those present proved that no one was smoking on the dance floor at that time, and no one saw her clothes being set on fire. That is to say, the fire started from the girl herself!
Similar incidents occur from time to time around the world, which has attracted the attention of scientists.

Some scientists speculate that the cause of the spontaneous combustion is the strange behavior of ball lightning, but this statement cannot explain the spontaneous combustion phenomenon under normal conditions without thunderstorms and lightning strikes.So some people say that the alcohol content in the human body is too high, which leads to the spontaneous combustion of alcohol in the human body.However, scientific experiments have proved that people who drink a lot will not catch fire even if they are close to an open flame, let alone make alcohol spontaneously ignite in the human body.Since these conjectures have been denied one by one, no one has been able to explain the strange phenomenon of spontaneous combustion so far.

Why Acupuncture Can Heal Diseases
Acupuncture is a unique Chinese method of treating diseases.Acupuncture and moxibustion pay attention to targeting acupuncture points. Acupoints are some points on the human skin that have special sensations. The doctor pricks your acupuncture points with silver needles, and you will have some corresponding sensations on your body.There are more than 700 such points in us, and they each perform their own functions and do not violate each other.

After the acupuncture points are inserted, our body will feel soreness, numbness, and swelling. These feelings seem to be traveling along a certain route. These routes are called meridians in Chinese medicine.

In ancient China, there are many stories about using acupuncture to save people. The most famous one is that Bian Que performed acupuncture on the prince of Guo who was mistakenly thought to be dead, bringing him back to life and witnessing the legend of his own funeral.So, can concepts such as acupuncture points and meridians be explained with modern medical concepts?
The theory of traditional Chinese medicine believes that meridians are distributed throughout the human body, including various organs, skin and muscles, just like a person's transportation system; and acupoints are only part of the meridians, and they are at the crossroads of this large transportation system.But in fact, meridians and acupuncture points are invisible, they are different from blood vessels and nerves, and can be clearly seen by dissection.

Therefore, some principles of acupuncture and moxibustion in traditional Chinese medicine cannot be fully explained by modern medicine.

Through various experiments, modern medicine has found that most of the acupuncture points in the human body are related to the nervous system, and there are nerve bundles in the deep layer of many acupuncture points; in addition, it is also closely related to blood vessels, lymphatic vessels, muscles and other tissues.Many scholars hope to use Western medical terminology to name acupoints, but the concepts of trigger point and movement point in Western medical terminology are not exactly the same as acupuncture points, so it is still difficult to name acupoints with Western medical theory.

Acupuncture and moxibustion in traditional Chinese medicine are closely related to meridians, but people have never been able to understand how Chinese medicine discovered meridians in ancient times when science and technology were very underdeveloped.And what is the basis for linking meridian and acupuncture together?This is still a difficult mystery for people today.

Why there is a strange feeling between twins

Twins are what we usually call twins. They are not only similar in appearance, but also very similar in personality, habits, and hobbies. There is even a wonderful connection between their illness and death.This peculiar phenomenon has attracted the attention of scientists.

There is such a pair of twin sisters in the UK.Their appearance, personality, thinking, actions and hobbies are exactly the same, and they always express their feelings in unison to external things, and even the tone of voice is the same.

When they spoke, even the gestures they made and the direction they pointed were the same.

There is also a pair of twin sisters who have lived in the two places for a long time. In order to surprise each other when they reunited, they cut their hair short at the same time.What is even more incredible is that both of them suffered from headaches of similar severity and at almost the same time.

In 1982, Harbin Medical University in China found the following situation of a pair of twin sisters in a survey of 40 pairs of twins: once the sister was taking an exam at school, she had a headache and nausea due to excessive mental stress.At that time, the twin sister happened to be watching a movie. She also suddenly felt paroxysmal pain in the head and wanted to vomit, so she had to leave the scene halfway.Another time, my younger sister was undergoing an operation in the hospital, and my twin sister who was doing housework at home also suddenly felt unbearable abdominal pain.When my sister returned home from the operation, her pain disappeared immediately, but no one could explain why she felt the pain at that time.

Scientists believe that these phenomena are not purely coincidental, but some kind of special induction between twins.The common genetics and common physiological and biochemical basis between twins are closely related to the appearance of these inductions, but scientists have not reached a consensus on how to cause this special induction.

Some people think that this induction is related to the time of fertilized egg division. The shorter the division time, the greater the similarity between twins, and the stronger the induction will be.

Another explanation holds that the phenomenon of mutual induction in the mind is a four-dimensional space-time genetic phenomenon that is more complicated than ordinary inheritance, and it will be controlled by length, width, height and time factors.For example, in some families with enuresis, the relief time of enuresis symptoms among the members also started at about the same time.Due to the same genetic factors of the twins, coupled with the same time factor, this telepathic phenomenon will appear.

It is also believed that this induction has gone beyond the scope of genetics, but a kind of bioelectric induction.

Because twins have very similar bioelectrical systems, they emit and receive almost identical responses.What is the truth, we can only wait for further analysis and research by scientists.

Can people really come back to life after death?

With the development of medicine, more and more patients have the experience of "resurrection".Scientists interviewed many people who had "death experiences" and found that most of them mentioned that they felt a sense of peace and relaxation when they were dying.Their consciousness seems to float away from the body, rise in a void, and then pass through a completely dark night until they see the dawn of dawn.

Between black and white, they will make some choices and struggles. Only those who are nostalgic for the light will return to the world.Some people will also see all their relatives and friends, including those who have passed away, all of them are glorious and tall like angels when they are dying.Some people can re-experience their own deeds during their lifetime at this time, just like watching a movie.

So, are these death experiences real or fake?What can they explain?Some scientists disagree with this.They believe that the dying patients only temporarily stop their heartbeat and breathing, but their brains continue to work. The so-called death experience should be some dreams when they are in a deep coma.

But there are also scientists who agree with this experience. Although they can't explain it well now, they are still working hard to explore the mystery.

How the relics in the body of the eminent monk are produced

Relics are the remains of the deceased after cremation, and they often appear in the ashes of Buddhist monks who have passed away and cremated.How did relics come about?Of course, it is different from the pathological phenomena such as gallstones and kidney stones that we generally talk about. Moreover, most of the eminent monks who left the relics are old people who are in good health and have died.

Therefore, some people explained that the vegetarian habit of the monks led to the accumulation of a large amount of fiber and minerals, and finally formed some kind of crystallization.But there are so many vegetarians in the world, and not all vegetarian monks leave relics!That doesn't work.Some people believe that after long-term practice, the mysterious substance relics will naturally form in the body of eminent monks who have attained the Tao.Now it seems that this is indeed a difficult problem that modern science cannot answer for the time being.

Why do color-changing people change color?

On the planet we live on, different races have different skin colors, and the skin color is determined by genetics and will not change greatly.But there are also some people who suddenly change their skin color. These "discoloration people" are very rare and confusing.

It is said that in the early 20s, there was an 80-year-old black boy named Manuel in Brazil.Once he was seriously ill and had a high fever for several days.Unexpectedly, after the high fever passed, Manuel turned into a white-skinned, blond-haired child.This was especially surprising, since his parents were both black, and none of his other relatives were white.

It is said that there is also a peculiar "discolored person" in the United States. She is a black young woman living in New York named Eddie.Once, Eddie was admitted to the hospital with tuberculosis.During the treatment, her heart suddenly stopped beating.After the doctor's all-out rescue, although Eddie saved his life, he remained in a coma for three weeks.During the coma, Eddie's skin gradually cracked and peeled off, finally revealing a layer of white and tender new skin, and he has since become a "caucasian".

Why do some people's skin color suddenly change?What exactly is causing the change in skin color?
For these questions, medical scientists have not yet found the answer.

A person who is not afraid of snake venom
In the great world, there are some people with poison in their bodies. They can often poison other creatures, but they are not harmed by the poison themselves.

There is such a person in Pittsburgh, USA, named Gran.One day, Gran was accidentally bitten by a rattlesnake.The rattlesnake is a very venomous snake, but after Gran was bitten, nothing happened, and the rattlesnake died before he could go far.Scientists tested Gran's blood and found cyanide in his blood.Scholars speculate that because Grann often works with highly toxic cyanide at work, he may have adapted to cyanide over time and accumulated a large amount of toxic substances in his body.

Therefore, any animal that bites him may be poisoned and die, even rattlesnakes are no exception.

Similar cases have occurred elsewhere.Why are these people not afraid of being bitten by poisonous snakes?Scientists still can't explain the mystery of this.

people who don't die

In the virgin forest of the Brazilian Amazon, there lived a man who could not die.It is said that this native named Oru Ugao would not feel pain if he was pierced by a long nail or bitten by a black bear, let alone die.

After a few weeks of observation, the scientist Andre from Sweden and three anthropologists found that Oulu could heal a fatal knife wound overnight, and the high fever could subside within a few minutes, so these scientists invited him to visit Big cities go for research.

When they took a plane to an altitude of [-] meters and set off for Rio de Janeiro, Olu suddenly opened the door and jumped off without a parachute.Andre and the others had no time to stop him, thinking that he would surely die.Unexpectedly, when the search team found him in the forest the next day, except for a slight injury at the corner of his eye, there was no trace of injury on his whole body.

people who are not afraid of water
There is such a person in the world, if you throw him (her) into any rivers, lakes and seas, he (she) can safely float on the water without sinking, even though he (she) can't swim.This is the strange man known as the "cork man".

In Adelaide, Australia, there was a fifty-year-old woman named Biggs who had never learned to swim.

Not long ago, she came to the swimming pool for the first time. As soon as she entered the water, she found herself floating to the surface like a piece of cork. She was very surprised.Later, she intentionally tied a stone to her body, but it still wouldn't sink underwater.For this reason, not only she herself is baffled, but even medical scientists have not figured out the reason so far.

In the United States, there is a man named Angelo Voachek who also has such a magical "ability".This burly man with a height of 1.85 meters can not only sleep peacefully in the water like a Simmons, but also roll freely on the water like a log.Once, out of curiosity, he hung a 10-kilogram lead put on his foot, and it still floated on the water for 8 hours.Another time, people did such an experiment: Put Voachek in a pocket made of 23 kg shells as a pendant, with only the head exposed, and put it into the sea.In this way, he has been floating in the sea for 8 hours.

Can the human body generate electricity?

There are such weird people in the world. They will be charged with high voltage, and anyone who comes into contact with them will be severely shocked.

There is such an electrified little girl in the United States. When she touches a metal doorknob, she will be knocked down by electricity, and she can also electrocute a cat herself.When seeing a doctor, the doctor touched her, and she was immediately stunned by the electric shock.A British woman also had a similar experience. As soon as she entered the bank, the computer system would be paralyzed, so she could only stay at home and take a shower desperately.

Neither of these people was born electrified, they just found themselves so by accident.

There are also some people who are born electrified.There is such a nurse in Lanzhou, China. When she walks, she can still hear the electric discharge sound from the impact of her shoes on the ground.An electrician in Guangzhou was also charged with electricity all over his body. No matter which part of his body he touched with an electric pen, the light of the electric pen was always red.

Why are these people electrified?Some scientists believe that it is because some of their abnormal emotions have accumulated too much static electricity in the body, which caused this abnormal phenomenon.However, this is only a speculation, and it is still difficult to know for sure what the facts are.

Why Some People Have Weird Tastes

Have you ever seen such a kind of people who only eat glass, iron nails, books, clothes, stones, centipedes, poisonous snakes, etc., and their tastes are particularly weird.

A young man in Morocco started eating glass at the age of 14, and has eaten more than 8000 of them.Those who have seen him eat from a glass say that he looks like he is munching on something delicious.Stranger things were yet to come. After the doctor examined his stomach, it was found to be perfectly functioning, and there was not even a speck of glass in it.

There is also an American woman who feeds on beautiful clothes. "Everyone has the love of beauty", but other people buy beautiful clothes to wear, but she uses them to eat.It is said that she likes to eat her husband's clothes the most. After the unlucky husband lost a lot of clothes inexplicably, he found out that those clothes had already become his wife's delicacy.
