However, the difference between mathematics and reality is that mathematics is purely rational, or purely objective, while reality is where rationality and emotion intersect, and objectivity and subjectivity dance together. Many times, rationality will be overwhelmed by emotion, and so will objectivity.
Being subjectively overturned, some phenomena such as "unreasonableness" and "countercurrent" appear.
Exercise makes people healthy, and health makes people live longer.
Exercise makes people live longer.
Xu Guangling savored these two sentences carefully in his heart.
Simply speaking from the perspective of answers, since Zhang Lao said this just now, there must be some differences in these two sentences. If it is an exam and it is a multiple-choice question, even if he does not know the reason, Xu Guangling probably
I will still answer the question like this: The first sentence is correct, the second sentence is incorrect, and there is a problem.
But is there any problem? If so, where is the problem? Xu Guangling doesn’t know.
In fact, compared to these two sentences, he was more familiar with the sentence "Life lies in movement". Therefore, he went through these three sentences over and over in his mind. He didn't find anything wrong, so Xu Guangling said it truthfully.
He said to Mr. Zhang: "Mr. Zhang, I don't think there is anything wrong with the statement 'Exercise makes people live longer'. I think it is right."
Mr. Zhang nodded in front, then finally turned around for the first time and said to Xu Guangling: "Xiao Xu, look at me, old man, how old do you think I am this year?"
"Mr. Zhang, your body is as strong as a pine, your energy is as calm as a bell, and your spirit is as dynamic as a dragon. When you look at people in your forties or fifties, if you don't know me, I will definitely guess that you are in your forties, Mr. Zhang. But since you said yesterday that you are more than forty years old,
I am two generations older than you, so you must be not only in your forties, but in your fifties. I guess you should be in your sixties, but not yet, right?"
"Ha ha ha ha!"
After hearing what Xu Guangling said, Mr. Zhang was a little overjoyed. He laughed for a while, then pointed at Xu Guangling and said: "Xiao Xu, Xiao Xu, I thought you were an honest child, but I didn't expect you were not honest at all.
! Even though I am in good spirits, old man, there is no way I can look at as many as forty or fifty people! You are just trying to make the old man happy, and you are telling lies with your eyes open."
Xu Guangling smiled and did not refute.
"However, 'The body is as strong as a pine, the energy is as calm as a bell, and the spirit is as dynamic as a dragon'. This is a really good saying. When the old man goes back, he will definitely find a big pen to write it down and hang it in his room. Just look at it every day.
Eat two more bowls of rice."
After saying this, Mr. Zhang shook his head, turned around again, and walked slowly, "Let's stop the age thing. No matter whether you can guess it, Xiao Xu, it is impossible for the old man to 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 worked as a herdsman for the landlord's family."
"With your old wisdom, you must be good at herding sheep." Xu Guangling said.
"Don't mention it, the old man really does a good job of herding the sheep, so the landlord is very relieved and leaves all the sheep to me. Xiao Xu, you may not know that sheep have very strong reproductive capabilities. An old sheep
They can raise 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, after a year, it can become more than a dozen or even dozens."
"The lamb is not like us humans. It is just born and can jump around as soon as it comes out of the belly of the old sheep."
Mr. Zhang was walking ahead and talking slowly.
"This is the survival ability of the animal kingdom. Wild animals do not have the superior living conditions that we humans have. Therefore, many types of small animals are born with the ability to run and jump. Only in this way can they survive. They are raised by humans.
Sheep have also inherited this characteristic of wild animals." Xu Guangling added later.
Saying this, Xu Guangling actually felt a little sad.
Because this knowledge point was not something he learned in the library, nor was it something he learned from the Internet, but something he learned from his father when he was young. - Xu’s father likes to watch the animal world in his spare time.
.
"Dad, bison don't have hands. What if they have a calf when they are chased by wolves? Mother cows can't hold the calf and run together." Xu Guangling asked his father, who was playing in front of the TV.
It depicts the entanglement and fight between wolves and bison.
"That's why calves can run when they are born!" Xu's father turned down the sound of the TV and explained in detail to Xu Guangling.
…
The sad emotions were restrained very well, so Xu Guangling's tone was calm and nothing out of the ordinary. Not to mention that Mr. Zhang was walking in front, even if he was face to face with Xu Guangling, it would be impossible to tell anything.
"Not bad, Xiao Xu." Mr. Zhang praised him very much, "You are right, that's what it is. But do you know the biggest difference between Lao Yang and Xiao Yang?"
Xu Guangling really doesn’t know this.
There is no way he could tell Mr. Zhang that the biggest difference between an old sheep and a little sheep is that one is an old sheep and the other is a little sheep. - If he really said that, it is estimated that Mr. Zhang's Tai Chi looks very calm and powerful, even if
Even if he is forced to transform, he has to transform into a bone-transforming cotton palm, so let him give it a try.
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 old sheep and little sheep is that the old sheep will be quieter. If you give it a pile of grass, or if it finds a source of grass, it will stand there and eat quietly.
.But lambs are different. Lambs are very playful and naughty. As mentioned before, they are lively and playful. They are always going back and forth and having fun."
"Not only lambs have this characteristic, but also calves, puppies, or our human children. When they have eaten enough and slept enough, they will always become very fluttering and cannot calm down." Zhang said.
There was a pause here, and then he continued: "So, they grow very fast, almost at a speed that we can completely see."
At this point, Mr. Zhang's tone became a little more meaningful: "Xiao Xu, do you know that there is an old saying in ancient books, which is called 'Those who pioneered, Xie Duzao early.'"
"Those who stay for a long time will fly high; those who take the lead will fly early. The first half of this sentence originated from Mozi in the pre-Qin Dynasty, and was later supplemented in the Ming Dynasty motto Lu Cai Gen Tan." Xu Guangling added an annotation to Zhang Lao's words,
In other words, "peng 叁".
"Yes, Xiao Xu, you are really good!" Mr. Zhang even turned around and gave Xu Guangling a thumbs up, then turned back and continued walking slowly: "A few years ago, Western scientists
A research report claims that our human genes and mouse genes are as much as 99% similar! This is also the reason why many medical developments use mice for experiments. The results obtained on mice can basically be applied to humans.
On the body."
When Mr. Zhang said this, he stopped again, turned around, faced Xu Guangling, his eyes were bright: "We humans have a life span of sixty or seventy years, sometimes eighty or ninety years, and no one can live more than a hundred years."
Not a few."
"Xiao Xu, do you know what the lifespan of a white mouse is?"
