Chapter 78 The first lesson
The woman is seven years old, and the kidney qi is strong... The husband is eight years old, and the kidney qi is strong...
Xu Guangling's feeling after watching this episode, how can I put it, I can't say I was shocked, but it was indeed quite a shock.
This paragraph directly solves some of his previous little questions or things he didn't understand.
For example, in ancient times, women were fourteen and crowned, and men were sixteen and crowned, indicating that they have grown up since then. Why are women only fourteen and men have to wait until sixteen? Xu Guangling now understands and understands why women generally mature earlier than men. Dare is not "universal", but complete.
For example, menopause.
When did the term menopause appear? Xu Guangling is not very clear, but it should not be too early. But the passage that Zhang Lao showed him directly told him that as early as thousands of years ago, Huaxia had clearly recorded the approximate age and origin of menopause in the text, and in the medical classics.
"The Western Bible says that God used a bone from Adam to create Eve." Seeing Xu Guangling reading it, Zhang Lao said slowly, "Modern medicine tells us that the bones of men and women are the same, and they are not the same. There is no such thing as more men than women or more women than men, but there is one fact that seems to tell us that men and women are not the same species."
"That is the biological clock of men, which is longer than that of women, not by a little bit, but by a full eighth! If from the genetic level, human beings have a lifespan limit, if a man is 800 years old , the woman is only seven hundred years old, and if the man is four hundred years old, the woman is only three hundred and fifty years old.”
Speaking of which, Zhang Lao smiled slightly at Xu Guangling, and then said: "Humble words, we talked about the heartbeat a few days ago, now you can guess, which one has a faster heartbeat, male or female? About how much faster? ?"
"Women, one-eighth faster?" Xu Guangling said.
Lao Zhang nodded: "It's almost the same, but because there are other influencing factors in the data, it is not one-eighth, but because of different individual conditions, there are large differences, and it is difficult to take an average."
Xu Guangling also nodded to show his understanding.
To put it simply, the overall heart rate of women is faster than that of men, it is certain, but how much faster is not easy to say.
"The same sentence, the pioneer, Xie Duzao. The metabolism of women is faster than that of men, which means that they mature earlier than men, and at the same time, they age faster than men. ." Zhang Lao said lightly, "This is a phenomenon that can be known without any data or theory, just by observation."
Xu Guangling nodded.
"However, a very interesting thing happened." Zhang Lao smiled slightly, "Humble words, guess again, which one has a longer average life expectancy for men and women?"
No need to guess, just relying on the content and tone of Zhang Lao's words at this time, Xu Guangling knew what the correct answer was.
But he was really aroused by Zhang Lao at this time, "It stands to reason that the average life expectancy of men should be longer than that of women, and it is about one-eighth longer. But Zhang Lao, you mean, the actual situation ,exactly the opposite?"
"Here is a very important indicator related to human body metabolism, blood pressure." Zhang Lao said, "Humble words, do you know blood pressure?"
Xu Guangling knew, but he didn't know.
I know that I have heard of it, and it seems that I have a general understanding of what blood pressure is. If I don’t know, I don’t know the specifics, so at this time he nodded and shook his head.
Seeing his reaction, Zhang Lao laughed, and said, "There is a saying in ancient China, called Hedong for thirty years and Hexi for thirty years, which means that the course of the Yellow River is not fixed and changes its course frequently. The result of changing course is, for example, Talking about a certain village or something, thirty years ago, it was still on the east side of the Yellow River, but thirty years later, it became on the west side of the Yellow River. It’s not that the location of the village has changed, but the location of the Yellow River has changed.”
Xu Guangling continued to nod to show his understanding.
In fact, he had heard this sentence before, and he didn’t need Zhang Lao’s explanation.
But Zhang Lao asked again: "Why did the Yellow River change its course?"
"Because of sediment deposition." Xu Guangling said.
In fact, there are many reasons for the diversion of the Yellow River, and there are many examples of people actively intervening to divert it, but even without any human intervention, the Yellow River will be diverted and the river will overflow. The root cause is sediment deposition.
Originally a good riverbed can hold so much water, but year after year, water flows through here, "Yellow River", as the name suggests, the Yellow River is yellow because of its turbidity and carries a lot of sediment. And these sediments are deposited all the way, gradually "filling up" the river bed, causing the water level to rise, putting more and more pressure on the river channels and dams on both sides of the river, so that in some places, the dams burst directly, causing the flood, causing flooding.
pressure?
Thinking of this, Xu Guangling suddenly realized something.
He seemed to understand why Zhang Lao mentioned the Yellow River when he was talking about blood pressure. Even, at this moment, another term suddenly appeared in Xu Guangling's mind, "Cerebral blood vessel rupture!" - Is that the Yellow River burst in some sense?
At this moment, Xu Guangling was a little enlightened, as if he suddenly understood a lot of things.
Of course, whether he understood correctly or not, he still needs Zhang Lao to solve his confusion.
"When the blood of the human body flows, the pressure on the blood vessels is the blood pressure." Zhang Lao said, "This is the same as the pressure caused by the river water on the river in the Yellow River."
Xu Guangling nodded.
With the words of Zhang Lao, it proves that what he thought just now is mostly correct, even if there is a small problem, the difference will not be too far.
"Why do you deliberately use the Yellow River as an example? In my humble words, can you understand?" Zhang Lao asked again.
The difference between the Yellow River and other rivers is that its water is turbid and contains a lot of sediment, which is also the biggest or fundamental difference.
With Lao Zhang's special reminder, it was impossible for Xu Guangling, a good student, to be unable to answer this question, but he still used a questioning sentence: "Because the blood of the human body, like the water of the Yellow River, contains a lot of impurities?"
Zhang Lao nodded, with a big smile on his face, expressing his approval, and then said: "Humans are just born, when they are children, their bodies belong to the 'He Qing Haiyan' period, but as they get older, their diet and their own metabolism are not comprehensive and ineffective. Perfection, as well as other less important reasons, are causing more and more impurities in the blood in the body. The more impurities, the more pressure the blood puts on the blood vessels.”
"Then the phenomenon or appearance that accompanies it is that with the increase of human age, the blood pressure gradually increases irrepressibly, until it rises to..."
