"As we said earlier, animals and plants, in many places, are not completely different, but on the contrary, they have a lot in common. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info But there is one place, animals and plants, that seem very different. Zhang Lao said, and he slightly accentuated the word "seem".

"Humble words, what do plants breathe through?" asked Zhang Lao at this time.

This is a very important feature of Zhang Lao's previous lectures, that is, he often asks questions, as he is now, and the scope of his questions is too much and too wide, sometimes Xu Guangling can answer, and sometimes Xu Guangling is simply dizzy and can't connect at all.

But Zhang Lao's profound knowledge is reflected every time like this, one inquiry, Xu Guangling can't connect, he will soon change to another inquiry, until Xu Guangling answers. -- And all these inquiries, though different, lead to what he is going to talk about next.

But the question he is asking now, Xu Guangling knows.

Plants, as a living being, "breathe", that's for sure. But plants don't have a nose and mouth like animals, so they certainly don't breathe through their nose and mouth, so through what?

Leaf?

But many trees lose their leaves in the winter.

Root?

But some plants have no roots, isn't there a word called "rootless bleaching"?

So the answer is that the plant uses its entire body surface to breathe, and wherever it comes into contact with the outside world, whether it is underground, underwater, or in the air, whether it is roots, stems, stems, or leaves, etc., it can be used to breathe.

Plants don't have a nose and mouth, but in a sense, it can also be said that there are noses and mouths everywhere, but their noses and mouths are "miniature", countless miniatures, breathing together.

Of course, it's hard to say whether it's "together" or not, and it is also possible that this part of the breath is breathed during this time period, and the breath is changed to another part of the breath during that time period, which is also possible. But like this kind of further specific knowledge, Xu Guangling must not know.

Xu Guangling told Elder Zhang that he had probably learned from 100,000 whys and the like.

Zhang Lao nodded, and then said something to Xu Guangling that made him a little dumbfounded: "So, humble words, have you ever thought that animals, or let's directly say humans, human bodies, can actually breathe like plants?"

Xu Guangling's reaction was ah.

This is probably the reaction of the vast majority of people after hearing this.

However, Zhang Lao diluted Xu Guangling's stunned eyes with only one sentence, "Humble words, where did the sweat on your body come from after you played Tai Chi in the morning?"

Do you need to ask?

It must be from the pores.

Then Zhang Lao said: "Humble words, water can flow out of the body surface, can it flow in from the body surface?"

This should not be a one-way glass, one side transmits light and the other side does not transmit light, so water should be able to flow in both directions on the surface of the human body, although it is a bit strange to flow in from the outside to the body, but "seeping in" should be no problem.

In fact, sweat only oozes out, so it's actually the same.

After Xu Guangling nodded, Zhang Lao said again: "Water can pass through the surface of the body, so oxygen, is it okay?"

Hearing this question, Xu Guangling was stunned again.

Even if he didn't know anything about biology or chemistry, he would probably have come up with this answer based on instinct: "Even 'so big and heavy' water can pass through, and 'so light and so small' oxygen or air, can't it?"

And what does it mean that oxygen can pass through the body's surface?

This means that the human body can breathe on the surface of the body just like a plant!

Through simple logical judgment, he came to this conclusion that was simply unquestionable, but for a while, Xu Guangling was confused, because this conclusion was obviously contrary to his cognition, or in other words, it was obviously inconsistent with "common sense".

At this time, Zhang Lao smiled and said to Xu Guangling: "It's a little difficult to accept?"

Xu Guangling nodded truthfully.

"Then do you believe it?" asked Elder Zhang again.

Of course I believe it! The facts are all here, and even if I don't believe it, this is also a fact! Xu Guangling just felt for a moment that this thing was very wonderful, but after recalling this matter in his mind, he smoothly accepted this new viewpoint.

But there are still problems.

That is, people's mouth and nose breathing cannot be interrupted, and if it is interrupted, it will inevitably suffocate.

Xu Guangling didn't ask this question, but Zhang Lao answered it directly for him, or he also knew that he must have this question, "Even if you eat every day, people may starve to death, if you don't eat enough." Even if you drink water every day, you can die of thirst if you don't drink enough. ”

In the third sentence, Zhang Lao did not say.

And Xu Guangling automatically added to Zhang Lao, which is also the interaction mode that the two have already developed when they teach these days, "Even if the body surface can breathe, people can suffocate to death, if the body surface breathing is not enough, it is not enough to meet the needs of the whole body." ”

After Xu Guangling finished saying this, Zhang Lao smiled slightly, and then said, "Humble words, now you understand?"

Xu Guangling nodded.

He did get it.

Therefore, the breathing of the human body, the breathing of the mouth and nose, and the breathing of the body, these two types of breathing, have always existed at the same time, and they have been going on at the same time. This can be verified in physiological experiments. But what ordinary people know, and can intuitively experience, is only breathing through the mouth and nose. Breathing on the surface of the body is not well known because it is not easy to perceive. Zhang Lao further explained.

Xu Guangling still nodded.

"Earlier, we talked about the problem of capillaries in the human body. Zhang Lao said slowly, "The baby's whole body is very smooth inside and out, so in this case, the baby's body surface breathing is also the most vigorous, and the body surface breathing is vigorous, which means that there is no obstacle in the metabolic problem." ”

"So the baby's skin, too, is the best, so good that it can be described as 'pure and flawless', which is difficult for any adult to compare, and adults, as they get older, the circulation of the body from the core to the periphery becomes less and less smooth. ”

Speaking of this, Zhang Lao said to Guangling: "Before, I said that through the practice of Tai Chi in the morning, as well as the move that Lao Chen taught you, you can let the circulation of qi and blood in your body move closer to the baby step by step, but this is only the first step. ”

"The second step is what happens to your right hand. ”

"To put it simply, your right hand, the palm of your right hand, can breathe. If you're swimming, you're going to dive longer than the average person, because your right palm, in a sense, is the gills of a fish. ”

"For the time being, there is only one right palm. ”

"After you have reached the palm of your left hand, the heart of your head, the heart of your left foot, and the heart of your right foot, which is the so-called 'five hearts', then diving, it is not a question of how long you can dive in the water, but ......" Speaking of this, Zhang Laowei smiled, like a child with a little cunning, "Humble words, or in the great master of Zhuangzi, there is a word, which corresponds to the previous 'real person's breath with heel', and it can also be said to be a supplement." ”

"What is that word?"
