Omniscient and Almighty

   Chapter 23 A=B, B=C, A≠C

  A=B, B=C, so A=C.

   Mathematically, this formula holds.

   But the difference between mathematics and reality is that mathematics is purely rational, or purely objective, while reality is the collision of rationality and sensibility, the dance of objectivity and subjectivity. In many cases, rationality will be overwhelmed by sensibility, and objectivity will be overturned subjectively, resulting in some phenomena such as "unreasonableness" and "countercurrent".

   Exercise makes people healthy, and health makes people live longer.

   Exercise promotes longevity.

  Xu Guangling savoured these two sentences in his heart.

   From the point of view of the answer, since Zhang Lao said this just now, there must be some differences in these two sentences. If it was an exam and it was a multiple-choice question, even if he didn't know why, Xu Guangling would still answer the question like this: the first sentence is correct, the latter sentence is wrong, there is a problem.

   But is there any problem? If so, what is the problem? Xu Guangling did not know.

In fact, compared to these two sentences, he was more familiar with the phrase "life lies in movement". Therefore, he tasted these three sentences over and over again in his mind and found nothing wrong, so Xu Guangling kept it true. He said to Zhang Lao: "Zhang Lao, I don't think there is anything wrong with the sentence 'exercise makes people live longer'. I think it is right."

   Lao Zhang nodded in front of him, then finally turned around for the first time and said to Xu Guangling, "Xiao Xu, look at the old man, how old do you think I am this year?"

"Lao Zhang, your body is as strong as a pine, your spirit is as deep as a bell, and your spirit is like a dragon. You look around like a forty or fifty people. If you don't know each other, I must guess that you are in your forties, but since you said yesterday that you are more than I'm two generations older, so I'm definitely not only in my forties, but in my fifties, I guess, you should be in your sixties, but not yet, right?"

"Ha ha ha ha!"

Hearing Xu Guangling's words, Zhang Lao was a little overjoyed for a while, and after laughing for a while, he pointed at Xu Guangling and said, "Xiao Xu, Xiao Xu, I thought you were an honest child, but I didn't think you were honest at all. Even though I am in good spirits, old man, it is absolutely impossible to 'look like forty or fifty people'! You are just trying to make the old man happy, and you are talking nonsense with your eyes open."

   Xu Guangling smiled without refuting.

"However, 'the body is as strong as a pine, the breath is as calm as a bell, and the spirit is as dynamic as a dragon' is really good. After the old man goes back, he must find a big pen to write it down and hang it in the room. Just by looking at it every day, you can Eat two more bowls of rice."

After saying this, Zhang Lao shook his head, turned around again, and walked slowly, "Let's stop about the age, no matter if you can guess Xiao Xu, the old man can't tell you. Little girl The age of the old man is a secret, and the age of the old man is also a secret. But what I want to tell you is that when the old man was young, he tended sheep for the landlord's house."

   "With your old wisdom, you must be a good sheep herder." Xu Guangling said.

"Don't tell me, the old man really kept the sheep well, so the landlord's family is also very relieved and handed over all the sheep to me. You may not know, Xiao Xu, the reproductive ability of sheep is very strong, an old sheep. It can bring two litters a year, and a litter can range from two to three to four or five, so even if there is only one old sheep, it can become a dozen or even dozens after a year."

   "The lamb is not like us. It is just born and comes out of the belly of the old sheep, and it can jump around."

   Zhang Lao walked in front and spoke slowly.

"This is the survival skill of the animal kingdom. Wild animals do not have the superior living conditions of our human beings, so many kinds of small animals are born and can run and jump. Only in this way can they survive. Sheep also have this characteristic of wild animals." Xu Guangling added later.

   After saying this, Xu Guangling was actually a little sad.

   Because he didn't know this knowledge in the library, nor did he know it from the Internet, but from his father when he was young. —Father Xu likes to watch the animal world in his spare time.

"Dad, the bison have no hands. When they are chased by wolves, what if they have a calf that is born? The mother cow can't run with the calf." Xu Guangling asked his father. The entanglement and struggle of wolves and bison herds.

   "That's why the calf is born to run!" Xu's father tuned the voice of the small TV and explained it in detail for Xu Guangling.

  …

   The sadness was restrained very well, so Xu Guangling's tone was calm and nothing out of the ordinary. Not to mention that Zhang always walks in front, even if he is face to face with Xu Guangling, it is impossible to see anything.

   "Not bad, Xiao Xu." Zhang Lao praised him very much in front of him, "You're right, it's like this. But Lao Yang and Xiao Yang, do you know what's the biggest difference between them?"

   This Xu Guangling really doesn't know.

   He could never tell Lao Zhang that the biggest difference between an old sheep and a lamb is that one is an old sheep and the other is a lamb. - If you really say that, it is estimated that Zhang Lao looks like a very calm and powerful Taijiquan. Even if he is forced to transform, he will transform into a bone-turning palm, and give him a shot.

   So Xu Guangling shook his head honestly and said at the same time, "I don't know."

"Then let me tell you, Xiao Xu, the biggest difference between the old sheep and the young sheep is that the old sheep will be quieter. If you give it a pile of grass, or it finds a grass source, it will stand there and eat quietly all the time. But the lambs are different. The lambs will be very jumpy and mischievous. As mentioned earlier, they are alive and kicking, and they are always going back and forth and having fun.”

"Not only lambs have this feature, but also calves, puppies, or our human children. When they are full and sleepy, they always become very thumping and can't calm down." Zhang Lao said There was a pause here, and then he continued: "So, they also grow very fast, almost at a speed that we can fully see, growing fast."

   At this point, Zhang Lao's tone became a bit meaningful: "Xiao Xu, do you know, there is an old saying in ancient books, called 'Open the predecessor, Xie Duzao.'"

"Fu Jiu, flying must be high, and pioneers, Xie Duzao. The first half of this sentence originated from Mozi in the pre-Qin Dynasty, and was later supplemented in the Ming Dynasty's motto Recorded Caigen Tan." Xu Guangling added a note to Zhang Lao's words, Or "pick up".

"Yes, Xiao Xu, you are really good!" Zhang Lao even turned around and gave a thumbs up to Xu Guangling, then turned around again and continued to walk slowly: "A few years ago, Western scientists According to the research report, our human genes and mouse genes are as high as 99% similar! This is also the reason why many medical development uses mice to do experiments, and the results obtained in mice can basically be applied to humans. body."

When Zhang Lao said this, he stopped again, turned around, and faced Xu Guangling with bright eyes: "Our human lifespan is sixty to seventy years, eighty or ninety years, and those who live to a hundred or more are also Not a few."

   "Xiao Xu, do you know what is the lifespan of a guinea pig?"
