Five Questions
Not long ago, there was a joke circulating on Weibo and WeChat that I have been unable to sleep well at night recently, and there are five problems that have been bothering me:
First, Yang Guo lived alone for 16 years with one arm. How did he cut his fingernails?
Second, Xiao Zhao has been wearing anklets for many years. How did he change his underpants?
Third, Mei Chaofeng has practiced nine Yin bones and claws for so many years. How did he wipe his buttocks?
Fourth, Sleeping Beauty has slept for so many years without brushing her teeth. Will she faint the prince?
Fifth, Butterfly Lovers have become butterflies. Butterflies have only seven days to live. Why don’t they become tortoise and live for a thousand years… This heart has broken my heart…
I don’t know if these five have puzzled many people, so I will simply answer these questions from the perspective of a doctor.
First, Yang Guo lived alone for 16 years with one arm. How did he cut his fingernails?
On this issue, we must first talk about why people have their nails cut. Because fingernails grow all their lives, why do they grow all their lives? Because it will wear and tear. There are also similar phenomena in what animals in nature. First of all, rodents are common. The incisors of these things grow all their lives. Because of the large wear and tear, we will see that mice need to chew things constantly. People who have raised hamsters must have some experience in this problem.
There is also the cat’s claws, which are constantly growing new because of their great wear and tear. Friends who keep cats at home must also have a deep understanding of this.
Of course, there are also some animals in nature that have adopted other strategies, such as sharks, which rely on the number of teeth to solve this problem. Sharks have many rows of teeth. The front teeth have fallen off and the back teeth have been filled up.
The above example is to show that many animals in nature have similar problems, but they can be solved without tools. In fact, it is really very simple, that is, biting nails. Since my son knows this method, Great Xia Yang has no reason not to know it.
Second, Xiao Zhao has been wearing anklets for many years. How did he change his underpants?
In fact, this solution does not come to mind at the stroke of the forehead. It is based on topology, a branch of mathematics. Topology is a branch of mathematics developed in modern times, which is used to study the invariant properties of various “spaces” under continuous changes.
In the 20th century, Topology has developed into a very important field in mathematics. This discipline is also called “science on rubber film”. For example, draw a big trap and a small circle on a balloon. No matter how you drag the balloon, the two circles will become what’s form, but the small circle will always be in the big circle. Topology is a science to study such things. For example, the famous seven bridges problem and the four colors problem are all problems in the field of topology.
So has topology contributed to the progress of medicine in what? Yes, it is also a great contribution. Watson and Crick discovered the double helix structure of DNA, which is exactly the application of topological theories to medical research. This story is too famous. I will go back to the details in the article on the history of medicine.
Later, these two won the Nobel Prize in Medicine and Physiology for this topological research achievement. Therefore, you know why we are far from this award, precisely because we have looked at the problem of Xiao Zhao changing underpants too simply and did not really understand the mathematical theory in it. It is true that all attention is knowledge.
Third, Mei Chaofeng has practiced nine Yin bones and claws for so many years. How did he wipe his buttocks?
The first thing that needs to be answered is how human beings wipe their buttocks. In ancient Rome, they used sticks to wipe clean. In fact, they can only be said to be barely clean. Moreover, the sticks used to wipe their buttocks in toilets are public, which are very bad from the perspective of hygiene and may cause the spread of infectious diseases.
British aristocrats seem better, but some are too extravagant, using salmon fillets. It is said that hemorrhoids can be prevented, but as an anorectal surgeon, I am very responsible to say that this makes no sense at all.
The Japanese royal family is said to use cicadas, which is also a very strange material. It is thin and brittle, not to mention, where did they get so many cicadas? I have doubts about this statement.
The French use thick hemp rope. It can only be said that such a choice is very courageous. In the movie “Wind”, rubbing the buttocks with thick hemp rope is a big * *. In fact, this kind of * * has a long history, and it is really frightening to think about it.
The way Indians wipe their buttocks is well known all over the world, that is, by hand. To this day, many Indians still maintain such a good tradition. Therefore, there will be such advanced faucet design in toilets in India, which is not available in other nationalities.
As for the Chinese, in ancient times, they used a kind of thing called toilet chips, which was to cut bamboo chips into suitable shapes. As you can imagine, the cost of this kind of thing was relatively high. Later, as the technology of making paper matured, coarse paper gradually replaced toilet chips and became the main force of wiping buttocks.
The hero mentioned in the question is Mei Chaofeng. She lived in the Song Dynasty, that is, when toilet chips and coarse paper were used together. Therefore, she is likely to use relatively long toilet chips to solve this problem. Although it is inconvenient to hold paper with long nails, the longer bamboo chips can still be done.
Fourth, Sleeping Beauty has slept for so many years without brushing her teeth. Will she faint the prince?
Halitosis is caused by Helicobacter pylori. This cow X-noisy bacterium is closely related to another common disease, peptic ulcer. The relationship between the two was clarified by a highly sacrificial doctor.
This man is Barry Marshall, an Australian doctor. In order to prove the relationship between Helicobacter pylori and ulcer, He did a very brave thing: He drank vomit from an ulcer, A few weeks later, he did suffer from ulcer. This confirms his point of view. It also changed the treatment of peptic ulcer from surgical removal to radical cure of Helicobacter pylori. Some people said that his knowledge in professional fields was not outstanding except for his supreme courage. However, it was precisely his courage that saved countless ulcer patients from surgery and won him the 2005 Nobel Prize in Medicine and Physiology.
Returning to Sleeping Beauty, if she had no Helicobacter pylori infection, halitosis would not be a big problem. Or the prince’s strategy is to give her a carbon 14 breath test before kissing her, which can make an effective evaluation.
Fifth, Butterfly Lovers have become butterflies. Butterflies have only seven days to live. Why don’t they become tortoise and live for a thousand years?
It is said that Liang Zhu’s story is set in the Eastern Jin Dynasty. The dynasty before the Jin Dynasty was the late Eastern Han Dynasty and the Three Kingdoms period. During this period of history, China suffered a very serious plague. Some scholars believe that it was the terrible plague that caused the population of China to plummet during this period of history.
Some data pointed out that China’s population was only 5 million at that time, the lowest in China’s history. Therefore, the biggest problem facing the emperor and the government is to increase the population. Therefore, the following policies will be issued.
Looking back on the story of Butterfly Lovers, the two were classmates for three years, and then died after another three years. According to the emperor’s decree, when they met, they were both hairy children who didn’t understand anything. This also explained why Butterfly Lovers didn’t notice all kinds of hints at the beginning, because they just didn’t understand.
Children’s sexual development is related to nutrition. Where can the nutritional status be better in the Jin Dynasty? Zhu Yingtai’s menarche will definitely come later than the children in modern society. That is to say, when Zhu Yingtai died, it was almost the first menarche. It was a period when girls changed to women.
We are comparing butterflies with tortoise. The development process of butterflies is completely abnormal. It is a qualitative leap to turn a beautiful butterfly from a cocoon broken by a big meat worm. However, the tortoise was a small tortoise when he was young, and a big tortoise when he was big. There was no big change in appearance. Zhu Yingtai was at the age when he broke the cocoon and became a butterfly. Butterfly is used as a metaphor, which is of course much more suitable than tortoise.
Again, this article is full of nonsense, just look at it.
