"I mourn the moment of my life and admire the infinity of the Yangtze River."
From the ancient poems, we can see that people have always yearned for "immortality". People are afraid of death and long for eternal life. In order to get the right to live forever, it can be said that they have hollowed out their minds. Just like Qin Shihuang in ancient times, he was extremely powerful, but he still hoped that immortality would recruit warlocks to refine the elixir for him. Another example is that Emperor Wu of the Han Dynasty repaired a huge "dew tray" with copper to receive dew and jade scraps, which was used by Emperor Wu of the Han Dynasty as a good medicine to prolong life ...
If people in ancient times had an inexplicable desire for "immortality" because they did not have enough scientific understanding of the aging and passing of life, then modern people are "re-exploring" the mystery of human life on the basis of science. Now the science and technology that promises to make people "stay young forever" is cryonics.
what is freezing technology
I believe many friends are as puzzled as the author when they hear "freezing". How can freezing make people live forever? In fact, the technology of freezing human body is still in the experimental stage. Its principle is to preserve human body or animals in an extremely low temperature environment, and hope that developed medical care can revive them in the future. Freezing the human body is expensive, even if it looks like "finding the secret of longevity".
but not many people can afford it because of the high price. So far, no one has been successfully resurrected after cold storage, and there are some technical problems in cryonics technology, such as brain cell death and brain loss of thinking ability after thawing for too long.
The world's first cryonics case
The world's first cryonics case occurred in the United States 53 years ago, and the frozen person was James Bedford, a psychology professor at the University of California. James Bedford once read a book by Dr. Robert Eetingue, The Foresight of Immortality, so James Bedford was very interested in the statement that "the human body can reverse death as long as it is frozen fast enough", so James Bedford contacted Dr. Robert Eetingue and expressed his wish to freeze his body.
James Bedford died in p>1967, and then James Bedford was frozen in a cryogenic liquid nitrogen tank. It has been 53 years since then. But James Bedford was frozen after his death, so he didn't come back to life successfully.
The first frozen man in China
Du Hong was born in Chongqing in 1955, and was one of the editors of the famous science fiction novel Three-body. This wonderful book "Three-body" is a space epic with lofty meaning with its grand story structure, novelty of scientific imagination and simplicity of humanistic reflection. "Three-body" embodies a high-level and high-level imagination. Yan Feng, a famous scholar, also spoke highly of this book. He once publicly commented that after reading Three-body, Liu Cixin raised China's science fiction literature to a world-class level. Some readers commented that the science fiction novel "Three-body" has surpassed the current science fiction system and is a masterpiece that all Chinese people should read.
Du Hong, the editor of Santi, suffers from pancreatic cancer. Du Hong, who is ill, doesn't have much time to live. However, Zhang Siyao, a filial daughter, is very reluctant to leave her mother, so she contacted her husband Lu Chen around and found an American freezing institution-the Alcaud Life Extension Foundation, one of the largest cryonics institutions in the world.
However, because the technical cost of freezing human body is too expensive, the daughter and son-in-law communicated with Du Hong and chose the freezing method of freezing the brain to freeze the brain of her mother Du Hong for 5 years. In May 215, Du Hong passed away. In the first hour after Du Hong's death, he began to infuse Du Hong with protective solution, inject anticoagulant into his body and press his heart with special equipment. After a series of operations, Du Hong's head was transported to the organization headquarters in Los Angeles, USA, and then kept in a low-temperature liquid nitrogen environment of -196℃, waiting for medical technology to allow his eyes to open again one day.
Today, Ms. Du Hong has been frozen for five years, but can the wish of "resurrection" after 5 years of freezing really come true? We can only wait and see.
Summary
People all want to live longer, perhaps because they are attached to the world, unwilling to leave their loved ones and so on. Therefore, these will continue to promote the continuous in-depth study of the secret of "longevity". Perhaps it has something to do with Du Hong's contact with science fiction, so she dared to try to freeze her brain after death, which is like a fable to ordinary people. However, it will take 5 years or even longer to know whether to successfully solve the secret of human life or to talk nonsense.
