The woman is seven years old and has strong kidney qi... The husband is eight years old and has strong kidney qi...
Xu Guangling's feeling after reading this paragraph was, how should I put it, shocked, but it was indeed a bit of a shock.
This paragraph directly solved some of his previous questions or things he didn't understand.
For example, in ancient times, when a woman was fourteen and had a haircut, and a man was crowned when he was sixteen, it meant that he had become an adult. Why was it that women were only fourteen and men had to wait until sixteen? Xu Guangling now understands and understands the reason why women generally mature earlier than men.
Dare to love is not "universal", but complete.
For example, menopause.
When did the term menopause appear? Xu Guangling wasn't sure, but it probably wasn't too early. But the passage that Mr. Zhang showed him directly told him that China was in the text thousands of years ago, and it was
Medical classics clearly record the approximate age and origin of menopause for men and women.
"The Western Bible says that God used a bone from Adam's body to create Eve." Seeing Xu Guangling finish reading, Mr. Zhang said slowly, "Modern medicine tells us that the bones in men and women are the same, and
There is no problem of more men than women or more women than men, but one fact seems to tell us that men and women are simply not the same species."
"That is, the male's biological clock is longer than the female's biological clock. It is not a little longer, but a full one-eighth longer! If from a genetic level, there is a lifespan limit for humans, if a male is eight hundred years old
, then the woman is only seven hundred years old, if the man is four hundred years old, the woman is only three hundred and fifty years old."
Having said this, Mr. Zhang smiled slightly at Xu Guangling, and then said: "I'm sorry, we talked about the heartbeat a few days ago. Now let's guess, which one has a faster heartbeat, men or women? How much faster is it?
?”
"Female, almost one-eighth?" Xu Guangling said.
Mr. Zhang nodded: "It's almost the same, but because there are other influencing factors in the data, it's not one-eighth. Instead, there are big differences due to different individual conditions, so it's difficult to get an average."
Xu Guangling also nodded to express his understanding.
To put it simply, it is certain that the overall heartbeat of women is faster than that of men, but by how much faster it is hard to say.
"As the saying goes, whoever starts first will die early. Women's metabolism is faster than men's metabolism, which means that they mature earlier than men. At the same time, they also age faster than men.
." Mr. Zhang said calmly, "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 Laowei smiled, "I'd like to ask you to guess again, which one has a longer average lifespan, men or women?"
No need to guess, Xu Guangling knew what the correct answer was just based on the content and tone of Mr. Zhang's words at this time.
But at this time, he was indeed aroused by Mr. Zhang, "Logically speaking, the average life span of men should be longer than that of women, and it is about one-eighth longer. But what you mean, Mr. Zhang, is that the actual situation
, just the opposite?"
"This involves an extremely important indicator related to human body metabolism, blood pressure." Mr. Zhang said, "I beg your pardon, do you know blood pressure?"
Xu Guangling knew it, but he didn't know it.
I know he has heard of it, and he seems to have a general understanding of what blood pressure is, but he just doesn't know the details, so at this time he nodded and then shook his head.
Seeing his reaction, Zhang Lao laughed and said: "There is a saying in ancient China, which is called Hedong in thirty years and Hexi in thirty years. It means that the course of the Yellow River is not fixed and often changes its course. The result of the change is, for example.
Let’s say that a certain village was on the east side of the Yellow River thirty years ago, but thirty years later, it is on the west side of the Yellow River. It’s not that the location of the village has changed, but that the location of the Yellow River has changed.”
Xu Guangling continued to nod, indicating that he understood.
In fact, he has heard this sentence before and does not need Mr. Zhang to explain it.
But Zhang Lao asked again: "Why did the Yellow River change its course?"
"Because of sedimentation," Xu Guangling said.
In fact, there are many reasons why the Yellow River changes its course, and there are many examples of active human intervention to change its course. However, even without any human intervention, the Yellow River will change its course and cause flooding. The fundamental reason is sedimentation.
Originally a good river bed could accommodate so much water, but year after year, water flows here. "Yellow River", as the name suggests, the reason why the Yellow River is yellow is because it is turbid and carries a lot of sediment.
As these sediments deposited along the way, they gradually "filled up" the river bed, causing the water level to rise and putting increasing pressure on the channels and dams on both sides of the river, so much so that in some areas, the dams directly burst, causing
Heavy water causes floods.
pressure?
Thinking of this, Xu Guangling suddenly realized something.
He seemed to understand why Mr. Zhang 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!" - Was that someone?
In this sense, the Yellow River broke its banks?
At this moment, Xu Guangling was suddenly enlightened, as if he understood a lot of things all at once.
Of course, whether he understood correctly or not, he still needed Mr. Zhang to clarify his doubts.
"When the blood of the human body flows, the pressure it exerts on the blood vessels is called blood pressure." Zhang Laodao said, "This is the same as the pressure exerted by the water on the river channel in the Yellow River."
Xu Guangling nodded.
Mr. Zhang's words proved that what he had just thought was generally correct. Even if there were some minor problems, the difference would not be too far off.
"Why do you specifically use the Yellow River as an example? I would like to ask you, do 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. This is also the biggest, or fundamental, difference.
With Mr. 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 human blood, like the water of the Yellow River, contains a lot of impurities?”
Mr. Zhang nodded, with a smile on his face, expressing his approval, and then said: "When humans are born, their bodies belong to the 'He Qing Hai Yan' period when they are children. However, as we grow older, our diet and the body's own metabolism are not complete, and we cannot
Perfection, as well as other less major reasons, are causing more and more impurities in the blood in the body. The more impurities, the greater the pressure the blood puts on the blood vessels."
"The accompanying phenomenon or appearance is that as humans age, blood pressure gradually and uncontrollably rises until it reaches..."
