From a very early age, human beings have dreamed of freezing human bodies. 1962, RobertEttinger, a physics teacher at the University of Michigan, published "Immortal Vision", in which he painted a wonderful blueprint: freezing people will be an important medical technology in the future. Critically ill patients will be able to be frozen and wait for the rescue of technological development.

If this technology is really mature, humans don't even need a time machine-as long as you close your eyes and freeze, open your eyes the next second, you may have been in 3000 AD.

The ideal is beautiful, but the reality is cruel. At that time, people had just begun to explore how to freeze people, and at the same time, to avoid cell tissue being crushed by water crystals, and how to thaw and recover later was even more unknown. However, these optimistic scientists have given high expectations to future generations: anyway, we will freeze people first and leave the rest to you!

The idea was quickly put into practice. 1967 65438+ 10 12, a man named James Bedford became the first person to be frozen in history. This is a milestone in human history. Today, he is still lying in the ultra-low temperature storage tank, waiting for someone to wake him up in the future.

James is a psychology professor in California. /kloc-0 was diagnosed with renal cancer in 965, and soon the tumor metastasized to the lungs. From 65438 to 0966, he met RobertNelson, president of California Cryogenic Society, and learned about this new freezing technology from him.

James is an adventurous man-1958. At the age of 64, he just retired and went to the savannah of Africa and the jungle of Amazon for a life-and-death adventure. It is conceivable that James is very interested in this technology and signed a volunteer letter to participate in the experiment, hoping that the future technology can finally revive himself and cure himself.

But at that time, he probably didn't think he would be the first experiment.

1967,65438+10 month, 12, 15 afternoon, James suffered from heart and lung failure in a sanatorium and was immediately sent to the nearest hospital for rescue.

In a hurry, the doctor gave first aid to James CPR, while James's wife and children frantically called Nelson. They know that James's illness is very dangerous, and cancer has tortured him to death. There is not much time to delay, and freezing has become the only way to save their loved ones. Nelson told them on the phone to put James on the ice bed to cool down. About an hour later, he appeared in the hospital with a full set of refrigeration equipment and several technicians.

In fact, the preparation for this freezing was hasty, and the technicians who implemented it were also trembling with nervousness. At this point, James has lost his heartbeat and spontaneous breathing. The technician first injected heparin into him to prevent blood coagulation. After that, they injected an antifreeze called DMSO into James's bilateral arteries, and kept his circulation through chest compression and balloon respirator ventilation.

James, a scrawny man, was lying on the bed, and the technicians gave him first aid with a mask and a press, while injecting a protective agent into his neck (network diagram).

After that, James was wrapped in a brand-new polyester sleeping bag and then put into an incubator filled with dry ice, and the temperature was as low as MINUS 79 degrees Celsius. After the temperature dropped completely, he left the hospital and was sent to a frozen warehouse in Arizona. Here, James was immediately transported to liquid nitrogen with a temperature of only MINUS 196 degrees Celsius.

After James lay in the liquid nitrogen tank, the technician filled it with liquid nitrogen (network diagram)

Liquid nitrogen is the best freezing method at present. They don't consume electricity, the temperature is constant, and accidents are unlikely to happen. James's "stay" time is set to be indefinite. When medicine can cure all diseases, it is when he wakes up.

199 1 On May 25th, James, who had been sleeping in liquid nitrogen for 24 years, was transferred again. This time, he was sent to a more advanced freezer. Temperature records show that during these 24 years, the highest temperature of his liquid nitrogen tank was only MINUS 145 degrees Celsius.

Since 1967 James was frozen, more than 400 people have been lying in liquid nitrogen, and as many as 3,000 people have signed the application form. Perhaps one day in the future, when technology is developed enough to free us from the shackles of physical illness and death, the first brave people in the world will open their eyes, arrive at their own tomorrow and restore their dreams of life.
