Omniscient and Almighty

Chapter 78 The First Lesson

When a woman is seven years old, her kidney qi is strong... her husband is eight years old, and her kidney qi is strong...

Xu Guangling's feeling after watching this paragraph, how should I put it, it's not shocking, but it is indeed quite shocking.

This paragraph directly solved some of his previous small questions or things he didn't understand.

For example, in ancient times, women's [-]th and ji, and men's [-]th crown, both indicated that they have grown up since then.Why are women only fourteen and men have to wait until sixteen?Xu Guangling now understands, and also understands the reason why women generally mature earlier than men, daring love is not "universal", but complete.

For example, menopause.

When did the term menopause appear?Xu Guangling didn't know for sure, but it shouldn't be too early.But the paragraph Mr. Zhang showed him directly told him that as early as thousands of years ago, Huaxia was in the text, and it was in the medical classics, which clearly recorded the approximate age and origin of male and female menopause.

"The Western Bible says that God used a bone from Adam to create Eve." Seeing Xu Guangling finish reading, Mr. Zhang said slowly, "Modern medicine tells us that the bones of men and women are the same, There is no question 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 biological clock of men is longer than that of women. It is not a little longer, but a full one-eighth longer! If from the genetic level, human beings have a lifespan limit, if a man is 350 years old , the female is only [-] years old, the male is [-] years old, and the female is only [-] years old."

Speaking of this, Zhang Lao smiled slightly at Xu Guangling, and then said: "Zhuoyan, we talked about the heartbeat problem a few days ago, now you can guess which heartbeat is faster, male or female? About how much faster?" ?”

"Female, one-eighth faster?" Xu Guangling said.

Zhang Lao nodded: "Almost, but because there are other influencing factors in the data, it is not one-eighth, but due to different individual conditions, there are large differences, and it is difficult to take an average."

Xu Guangling also nodded, expressing his understanding.

To put it simply, it is certain that women's overall heartbeat is faster than men's, but how much faster is hard to say.

"It's still the same sentence, Xie Duzao is the first one. 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 by observation alone without any data or theory."

Xu Guangling nodded.

"However, a very interesting thing happened." Zhang Lao smiled slightly, "Zhuo Yan, guess again, which one has a longer average life expectancy, male or female?"

No need to guess, just relying on the content and tone of Zhang Lao's words at this time, Xu Guangling knows what the correct answer is.

But at this time, he was indeed aroused by Zhang Lao, "It is reasonable to say that the average life expectancy of men should be longer than that of women, and it is about one-eighth longer. But what you mean by Zhang Lao is the actual situation. ,exactly the opposite?"

"This involves an extremely important indicator related to human body metabolism, blood pressure." Zhang Lao said, "Zhuoyan, do you know blood pressure?"

Xu Guangling knew, but didn't know.

I know I have heard of it, and I seem to understand what blood pressure is. If I don’t know, I don’t know the details, so at this time he nodded and shook his head.

Seeing his reaction, Mr. Zhang laughed, and then said: "There is a saying in ancient China called 30 years in the east and 30 years in the west, which means that the course of the Yellow River is not fixed and often changes its course. The result of the change is that, for example, a certain A village or something like that was on the east side of the Yellow River 30 years ago, but it is on the west side of the Yellow River 30 years later. It’s not that the location of the village has changed, but the location of the Yellow River channel has changed.”

Xu Guangling continued to nod, expressing his understanding.

In fact, he had heard this sentence before, and Zhang Lao didn't need to explain it.

But Zhang Lao asked again: "Why did the Yellow River divert?"

"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 diversions caused by human intervention. However, even without any human intervention, the Yellow River will divert and flood. The root cause is sediment deposition.

Originally a good river bed can hold so much water, but year after year, water flows here. And these sediments deposited all the way, gradually "filled up" the river bed, causing the water level to rise, and putting more and more pressure on the river channels and dams on both sides of the river, so that in some areas, the dykes burst directly and happened. Floods, causing 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, "Break of blood vessels in the brain!"--Is that the Yellow River embankment burst in some sense?

At this moment, Xu Guangling suddenly became enlightened, as if he understood a lot of things at once.

Of course, whether he understands correctly or not, Zhang Lao needs to clarify.

"When the blood of the human body flows, the pressure on the blood vessels is blood pressure." Zhang Laodao, "This is the same as the pressure on the river channel caused by the river water in the Yellow River."

Xu Guangling nodded.

With Zhang Lao's words, it proves that what he thought just now is probably correct, even if there is a small problem, the difference will not be too far away.

"Why do you want to use the Yellow River as an example? Zhuoyan, 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 is impossible for Xu Guangling, a good student, to be unable to answer this question, but he still used interrogative sentences: "Because the blood of the human body, 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: "Human beings are just born, and when they are children, their bodies belong to the 'He Qing Hai Yan' period, but as they grow older, their diet and metabolism of the body itself are not complete, and the metabolism is not perfect. Perfection, as well as other less important reasons, are causing more and more impurities in the blood in the body. The more impurities, the greater the pressure the blood exerts on the blood vessels."

"Then the phenomenon or appearance that accompanies it is that as humans age, blood pressure also gradually rises irresistibly, until it rises to..."
