Starting from the lifting of human restrictions

Chapter 6 Libraries

Sham Shui Po, outside the municipal building on Po Po Road, a yellow taxi slowly pulled into the parking area.

"Hey, we're here, 110 Mosquito, this is the nearest large library in front of us. I heard it was newly opened a few years ago."

In the driver's seat of the taxi, a chunky middle-aged taxi driver leaned sideways, pointed to the building outside the window, and said to Yang Chu who was sitting in the back row.

"Thank you!"

Yang Chu glanced at the building outside the window, took out a 100 yuan and a ten yuan Hong Kong dollar from his wallet, handed them to the other party, opened the car door and got out of the taxi.

All the way into the Municipal Building, up to the second floor, he came to the destination of his trip, the Poon Road Public Library in Sham Shui Po.

Yang Chu was ready to look up the books to see if he could find a solution from these books.

He did not choose to seek medical help or other professionals for help. Hong Kong Island is a capitalist society. With less than a thousand Hong Kong dollars left in his pocket, he can even make an appointment in some high-end clinics and professional medical staff. No qualifications.

To take a step back, even if he can contact some suitable institutions and professionals, let's not say whether he can solve his sleep problem, but it is certain that he will become a research and experimental object in a short period of time.

Of course, in the face of life and death, there is nothing that cannot be compromised.

It's just that there is no way out until the end, Yang Chu will not easily let others dominate his destiny.

He actually didn't know why he thought so...

The memory of the previous life has been missing a lot in his mind, and the trajectory of his life that he can remember in the previous life has become a little vague.

Fortunately, thinking and behavioral logic, and even a lot of knowledge that has been learned is still preserved.

When faced with these problems he encountered, his brain consciousness was able to make judgments and choices based on the current situation.

As for whether this choice is correct and effective, and whether it can solve the current problem, there is no way to think further.

Moreover, these slightly mixed thoughts were actually just fleeting thoughts that passed by Yang Chu when he just took a taxi and sat quietly in the back of the car.

Poon Road Public Library has bright and clean windows and a good environment.

The library doesn't look too big, and there are four or five employees working with brooches on their chests.

As soon as Yang Chu entered the library, he quickly glanced at the various partitions on the bookshelf, and quickly found the biological and medical areas.

There are not too many books, about the size of four long rows of bookshelves, and there are new and old books on the bookshelves. It can be seen that in addition to purchasing, some of them should come from private donations.

Most of these books are in traditional Chinese, and a few also have one or two in simplified Chinese among them, and a large part of them are in English, but Yang Chu does not seem to be under too much pressure.

Yang Chu quickly swept across the rows of bookshelves, and quickly stood on one of the bookshelves, pulling out a book from above.

The title of the book is "The Most Familiar Stranger", and the subtitle is a journey of self-recognition and potential discovery.

Yang Chu roughly glanced at the catalogue and hurriedly turned over a few pages. Feeling that he should be able to read it, he put it on the bookshelf at hand and continued to look for other books.

He picked up two more books called "Efficient Rest Method" and "Concentrated Sleep Method". He roughly glanced at the catalogue and intuitively found something he needed, put them on the shelf in front of him, and continued. look for.

"can not fall asleep?"

Just as Yang Chu was carefully selecting books, a gentle voice suddenly sounded beside him.

Yang Chu turned his head to look, and saw a handsome young man with headphones in his ears, who was pushing a lot of books past him on a small cart.

It looks like it should be a library staff member.

"Yes, my mind can't be empty, and I can't fall asleep." Yang Chu casually agreed.

"I often can't sleep at night."

With a shy and gentle smile on his face, the handsome young man put a few books on the bookshelf next to him and said, "If you want to try to sleep well, you can look at this—"

With that said, the handsome young man handed an old book in his hand to Yang Chu.

Yang Chu took the book and glanced at the title "Why We Sleep", which seemed to be what he needed, so he nodded lightly: "Thank you!"

"You're welcome!"

The handsome young man smiled, pushed the books on the trolley and walked towards the other bookshelves.

Yang Chu casually glanced at the books on the other party's cart, and the books "Why We Born Here", "The Weakness of Human Nature", and "Personality Test" came into view.

After the handsome young man left, Yang Chu didn't pay much attention to it, and was still browsing in front of the rows of bookshelves.

He didn't get a book and started reading now, but kept looking for the books he wanted from the bookshelf and put them in front of him.

The current body is still standing and walking. In addition to controlling the major internal systems of the body, his brain consciousness also controls the motor system. Without the subconscious controlling the body, if he is a little absorbed in reading, the whole person will not be able to. Will stand, but will suddenly fall.

If he wants to read for a longer time, he still wants to reduce the investment of his brain consciousness in other areas as much as possible.

"Save Your Sleep", "Wake Up Your Sleeping Brain", "Efficient Brain Work Method", "Second Brain", "Brain Restoration Technique", "Explanation of Consciousness", "Brain Nerve Atlas", "Introduction to Brain Science" ...

Yang Chu found more than ten books, new or old, from the bookshelf in a row. As long as he thought it might be useful, or could open up some of his ideas, he would stay.

Then, holding a pile of books, he walked to the reading seat not far from the bookshelf.

A person with dozens of books in his arms and sat down on his seat naturally attracted the attention of many people around him.

But Yang Chu didn't pay attention to other people's same eyes. After sitting down, he straightened his posture and began to read books.

The first thing Yang Chu wants to understand is why people sleep.

He seems to have some memories of this aspect in his consciousness, but it is not clear enough, and many seem to be forgotten.

Moreover, these contents focus not on the question of why people sleep, but on the harmful consequences of lack of sleep if they do not sleep, the harm of staying up late to the body, and so on.

Dizziness, physical and mental exhaustion, inability to concentrate, unable to remember things, mind blank when thinking, decreased ability to respond to incidents, difficult emotional control, more likely to get sick, more likely to develop cancer, more likely to age, and feel unwell all over the body such as.

Yang Chu knew about the serious consequences of these lack of sleep, but they were far from the answers he wanted.

After opening a few books, Yang Chu slowly found some explanations.

It should be said to be speculation and conjecture.

The first is that sleep is for maintaining energy.

At the beginning of evolution, animals lacked food.Sleep is to lower the basal metabolic rate, allow energy to be conserved, and restore energy lost during the day, similar to the need for hibernation in some animals.

But this statement now seems inaccurate. With the advancement of evolution, energy intake is no longer a problem for humans.

If sleep is to maintain energy, then add enough energy, people can not sleep.

So, in addition to saving energy, sleep must have other meanings.

The second argument is that sleep is for memory.

Sleep helps in the repair of nerve tissue, and has a certain protective and consolidation effect on memory.

There is some truth to this statement, and it can be recognized, but it still seems insufficient.

The third is that it can efficiently remove metabolic wastes in the brain during sleep, thereby restoring vitality.

Most metabolites in the human brain are discharged from brain cells into the interstitial fluid between cells.Another secreted liquid, cerebrospinal fluid, has the function of supplying nutrients to the brain and expelling metabolic wastes.The cerebrospinal fluid flows into the brain along the periarterial space, exchanges with the interstitial fluid of brain cells, and carries the metabolic wastes of the intercellular fluid to the perivenous space, and then drains out of the brain.

The intercellular spaces in the brain are larger during sleep than when awake, which means that cerebrospinal fluid is more likely to enter the brain and exchange with interstitial fluid during sleep. Sleep may prevent the accumulation of toxic metabolites that damage brain cells.

Sleeping is like taking a bath with cerebrospinal fluid to wash away the accumulated metabolic waste.The role of sleep can be described as a real "detox".

Yang Chu still thinks there is some truth to this statement.

Probably not quite, but part of the role of sleep should have this.

In addition, it is said that related to immunity, sleep produces a specific secreted protein with antibacterial properties.

People often feel tired and sleepy during illness, but in fact, the increased need for sleep during illness is caused by the release of signaling molecules from the autoimmune and nervous system, not the infectious agent itself.

Others, such as sleep, were originally just a primitive function that organisms fulfilled at the beginning of evolution. As for what this primitive function is, there is no conclusion.Later, in the process of evolution, sleep slowly gained more functions.

Sleep is to improve brain function, sleep is related to the circadian rhythm of the earth, sleep at night is to avoid natural enemies and so on.

From many books, Yang Chu did not get an exact and complete answer.

He didn't know that there were too few books here, or that there was no such answer for the time being based on human cognition of themselves and creatures.

But Yang Chu felt that he had already gained something.

Moreover, Yang Chu found a few words in this pile of books that made him feel a little interesting.

One is that we are not sleeping at all, "awakening" is what we have to do.

Most low-level creatures have neither sleep nor awakening, and have been in a state of low perception and low motivation for a long time.

Such as all plants, bacteria, viruses, plankton, even insects and so on.They outnumber humans and all animals combined.They move mechanically day after day and never wake up.Human beings have awakened from lower biological species, gained wisdom, and gained the active power to control their own lives.

In these books, Yang Chu also learned a lot of knowledge that he didn't know before——

In mammals and birds, sleep can be divided into two major stages—REM sleep and non-REM sleep—by analyzing eye movements during sleep.

REM sleep is characterized by rapid eye movements, but also includes high-frequency, low-swing EEG and reduced activity of EMG.Most dreams occur at this stage.

Non-REM sleep accounts for approximately 75-80% of adult sleep.During non-REM sleep, dreams are relatively rare.Non-REM sleep consists of 4 stages, one, two, two stages are light sleep, and three and four stages are deep sleep.Each stage of sleep has different characteristics.

There are also many animals that sleep less than humans, such as elephants, which only need two hours of sleep a day.

Some marine mammals, such as whales and dolphins, don't even need to put their entire brains to sleep. Their left and right brains can take turns resting, so that half of the brain is always awake at any time to undertake the daily tasks. Work.Some small animals don't even sleep much in order to prevent them from being caught by predators.

In addition to these books on the surface of the water, Yang Chu found something worth trying in some books on the "subconscious mind".

Develop a subconscious mind that you can control.

For example, if an ordinary person suddenly sees something flying towards him, or encounters a frontal attack, he will subconsciously close his eyes.

However, a trained boxer or other fighter has completely mastered this subconscious instinct during long-term training. When facing an attack, not only will he not close his eyes, but he will see the route of the attack clearly. Let your body dodge.

"How is it? Seeing that you have been sitting for almost a day, have you found the solution you want to solve sleep?"

A gentle voice sounded in my ear again.

Yang Chu raised his head and saw the handsome young man working in the library, who was standing at the table next to him and looked at him.

Only then did he realize that it was already dark outside, and it was already night.

Except for the handsome young man in front of him, everyone else in the library had already left.

"It's a bit of a gain, but the specifics will only be known after trying it out."

Yang Chu also understood the other party's intention, and the library should be about to close.This afternoon, he has gained a lot, and for some reason, he has read all the books he has selected, and he has also understood a few things.

Close the book and stand up from the table.

But it was probably due to sitting for too long. Although he kept his heart beating and blood circulation all the time, there was still some blood stagnation in his lower limbs, and he unconsciously fell to the side after getting up.

"careful!"

The handsome young man had quick eyes and quick hands, he supported Yang Chu and said with a smile, "I see that you haven't moved since you were sitting, so you need to stand up a little and move..."

"Thank you, I'm fine!"

Yang Chu slightly accelerated the beating of his heart, and the blood circulation speed of his body increased, but within ten seconds, the paralyzed state of the lower body had been removed, and there was no need to continue to support him.

"You recovered quickly!"

The handsome young man watched Yang Chu recover in a short time, and there was a slight surprise on his face.

"Just sit for a while."

Yang Chu smiled and asked the handsome young man in front of him, "By the way, where is the restroom?"

Having said that, Yang Chu glanced at the rectangular brooch on the chest of the handsome young man. The brooch was a work card with several English letters on it - XIXI.

"My name is Xu Xi."

The handsome young man noticed Yang Chu's eyes, still showing a shy smile, and then pointed to the other side of the library, "You just turn the corner."
