He didn't know what kind of effect such understanding had on the heart and consciousness, nor what kind of effect the heart and consciousness had on the body. In short, Xu Guangling only felt that the operation of Fuxi Jue in his body was once again deeper and more subtle.
It was as if it had turned into a small lake. From the sky, or above the small lake, the continuous drizzle fell and soaked the small lake.
It also infiltrated his entire body and mind.
So, Xu Guangling stood in front of the window like this again, and before he knew it, it was a whole night.
After waking up, Xu Guangling was sure of one thing.
It was also one of the experiences he had been feeling in subtle ways these days.
At first, before the red flower representing the heart, the first flower of the five-color flower, bloomed, Xu Guangling's level of perception of the body was very shallow and could not penetrate deeply into the internal organs.
And when the red flower blooms, the heart becomes his base of perception.
Then, starting from this stronghold, you can feel the flow of blood, feel the limbs, and feel other organs.
When the yellow flower representing the spleen also bloomed, Xu Guangling discovered something.
That is before blooming, the spleen will filter the blood, but it itself seems to be metabolizing very frequently.
Xu Guangling felt that almost every moment, the spleen itself had some fine impurities flowing out with the blood. Based on speculation, Xu Guangling judged that this was the metabolism of the spleen, or cell renewal.
The new replaces the old.
However, his perception cannot yet penetrate to this level, so on this point, he only has vague perceptions, conjectures and judgments.
But when the yellow flowers bloom, this renewal and metabolism are gone.
In addition to the much clearer blood in the body, the spleen itself is also as clear as water, with no impurities flowing out of it.
what does that mean?
In the evening of that day, during chat time, Xu Guangling asked Mr. Zhang this question.
"Teacher, how long is the lifespan of a single cell in our body?" Xu Guangling asked.
Xu Guangling thought that this question should be common sense to the old man, but unexpectedly, as he asked, not only Mr. Zhang, but also Mr. Chen, both of them fell silent.
After a while, Mr. Zhang finally spoke:
"I'd like to say that it's hard to answer this question."
"Let me give you an example first. An ant nest is generally composed of queen ants, reproductive ants, worker ants, and soldier ants. However, although they are all ants, their natural lifespans are quite different."
"The queen ant has the longest lifespan, which can last more than ten years or even decades."
"Male ants have the shortest life span among reproductive ants, generally no more than a month. Their mission is to reproduce, and once they complete their mission, they die immediately."
"The lifespan of worker ants and soldier ants is somewhere in between."
"Ants from the same ant nest have such huge differences in their life spans."
Having said this, Mr. Zhang smiled slightly and said, "My teacher once did an experiment. If the male ants are not allowed to reproduce, and if the worker ants and soldier ants are not allowed to work and fight, in a good living environment, their lifespan will be greatly reduced."
, will it be extended?”
"The answer is yes."
"Their lifespan has indeed been extended, and it has been extended significantly."
"But can it ultimately be extended to the same lifespan as the queen ants? This is not certain. Because I cannot be sure that the environment I create for them is the most suitable environment for them."
Having said this, Mr. Zhang paused.
After about thirty seconds, the old man said: "The situation in our body is roughly similar to that of an ant nest. Or essentially, the two are the same. Of course, this is not certain."
"In our body, brain cells have the longest lifespan, almost accompanying us throughout our lives."
"Heart cells follow, about twenty years."
"Why do brain cells have the longest lifespan? Subjectively, it is because it is the most important, and objectively, it is because its living environment is the best. I have told you about this before, the blood-brain barrier."
Xu Guangling nodded.
The so-called blood-brain barrier, simply put, is the road that supplies blood to the brain. There is a barrier, just like the security booth at the entrance of some communities, which plays a certain protective and filtering role.
Many impurities in the blood cannot pass through this barrier.
What the brain enjoys is "high-quality blood."
Other parts of the body do not receive this treatment.
"The complete opposite is the lifespan of cells in the small intestine."
"Because they fight on the front line of blood production, the lifespan of small intestinal cells is only days, or one day, or several days, or even less than one day."
"In addition, the lifespans of cells in other tissues in the human body also vary. Some are measured in years, and some are measured in months."
Having said this, Mr. Zhang paused again, and then asked Xu Guangling: "Zhuyan, what do you think?"
Xu Guangling said: "Assuming that there is a barrier in the small intestine, like the blood-brain barrier, so that our entire body can enjoy high-quality blood like the brain, then will the lifespan of various tissue cells in the human body be extended?
Extended to the same life span as brain cells?”
After hearing what he said, the two old men laughed.
Chen Zhihe, on the other hand, listened honestly or quietly.
"When a person dies, the brain cells do not die."
"How long can a brain cell survive if an environment suitable for its survival can be created?"
"have no idea."
"Maybe a few minutes, maybe a few hours, maybe a few days, maybe a few months, maybe a few years, maybe decades or hundreds of years, maybe...longer."
"The only thing we know for sure is that the lifespan of brain cells is longer than the lifespan of our entire body."
"Why is the entire body short-lived?"
"Just because the environment in which it lives is not as good as the brain."
"So improving the body's environment is to increase lifespan, and the first thing to do is diet."
"Improving diet means improving the environment of the small intestine, which will allow cells in the small intestine to survive longer and have a lower metabolic frequency. The expenditure and burden on the body in this area will also be reduced."
"At the same time, improving your diet means improving your blood and improving the living environment of all tissue cells in your body."
"That's why there is such a saying in ancient books."
"If you want to live forever, your belly must always be clear."
“That’s why many doctors and health experts in ancient times have tried to ‘die the grain’.”
Inediate means not eating.
You may not eat for three days, or you may not eat for five or seven days, or even longer.
Of course, there are also short-term ones, one or two days or even one or two meals.
For example, there is this description in "A Dream of Red Mansions": "The customs and secrets in this Jia's house, regardless of whether they are high or low, only have a slight cold or cough. The main thing is to purify the hungry, and the second is to take medicine to recuperate."
Net hunger means just one, two or three meals.
"Teacher, Mr. Chen, have you ever tried fasting?" Hearing this, Xu Guangling asked curiously.
"I've definitely tried it, but it doesn't mean much," Mr. Chen said.
"There are advantages to living without grains, but there are also disadvantages. I am still not sure whether the advantages outweigh the disadvantages or the disadvantages outweigh the advantages, so I gave up after trying it for a stage." Zhang Laodao said.
Xu Guangling nodded.
"Sorry, why did you bring up the issue of cell lifespan?" The topic had basically come to an end, and then Mr. Zhang asked.
