In fact, the life expectancy of human beings has been extended very fast, there are 559 emperors in the history of our country, their average life expectancy is 39.2 years, and in 2019, the average life expectancy of our country is 77.3 years, which is doubled.
In 2016, Ma Yun said that humans will solve the mysteries of the human body in 30 years, and Google chief engineer Kurzwell also said that before 2045, human beings will not be bound by lifespan. In 2021, the famous British life scientist Aubrey de Grey said that human beings will break through the limits of life by 2036. The speeches of the big guys make people have infinite expectations for the future, can human beings really usher in immortality? And it's in our generation?
In 2015, the editor of the science fiction novel "Three-Body Problem", Chongqing female writer Du Hong was terminally ill, her daughter and son-in-law took her around to seek medical treatment without results, perhaps affected by science fiction, soon Du Hong lay in the freezer, she became the first frozen person in China, with a vision for the future, hoping to come out after 50 years, with advanced medical technology to treat herself and reunite with her family.
Frozen human technology has very harsh conditions, first of all, it must be frozen within 5-8 minutes after the death of the person. Secondly, it must be a liquid nitrogen freezer at minus 196°, and even the cheapest freezing solution requires 750,000 yuan.
The alcor foundation in the United States that accepted Du Hong's freezing plan business claimed that Du Hong would be successfully resurrected in 2065. But it ushered in a voice of doubt in the industry, many scientists said that this is a kind of cheating people of money, scientist Grishchenko, a scientist specializing in cryobiology research, said bluntly: "Even if a healthy living person is frozen for 50 years, it is impossible to survive after thawing, let alone a dead person." ”
However, there are also many scientists who are very optimistic about this technology, and the director of the "Human Future Institute" in Oxford and many researchers have booked this refrigeration business, hoping that if they can't hold on, they can use future technology to save themselves.
So far, there are more than 500 frozen people in the world, and the world's first frozen man, Bedford, has been frozen for 54 years, but it is clear that the current science and technology cannot save his life, and perhaps he will need to freeze for another 50 years.
In addition to freezing technology, the scientific community has other "immortal" attempts, such as "brain-computer interface technology" Scientists intend to upload human consciousness to the machine end, so that although they will lose their instincts as creatures, they can retain their consciousness and achieve an alternative immortality without eating, drinking or breathing.
At present, the scientific research team of this technology has successfully implanted the chip into the brains of pigs and monkeys, scanned their brain waves, and allowed monkeys to play games through consciousness, which is very magical.
Since ancient times, mankind's pursuit of immortality has never stopped, Qin Shi Huang once sent Xu Fu to seek immortal medicine, many wise kings of successive dynasties were also obsessed with immortal elixirs, and the West is spreading the alchemy of immortality, and even Newton once spent 30 years to study alchemy. However, those of them who had stood at the top of the era did not succeed and eventually turned into dry bones in the grave.
With the increasing development of science, scientists have pointed out that the stories of those seeking immortals and asking for medicine are nonsense, but people's pursuit of immortality has not stopped, because there is a more down-to-earth approach, that is, science, frozen people are just one of the attempts, the pursuit of life is the eternal goal of mankind, China's first frozen man Du Hong can not be rescued in 50 years, let time answer it!
