In the future, people can be immortal by freezing the dead to revive them?

The idea of ​​’crazy’ thought only in fiction movies but actually exists in real life.
In preparation for death, many people plan to dispose of their remains in different forms. Some people choose coffins, others plan to be cremated, and their ashes will be scattered at special locations, even turned into vinyl records. However, for a few hundred thousand dollars, many people choose to freeze their bodies in the hope of reviving them through advances in science and technology in the future.

Cryogenic technology and the promise of bringing the dead back to life (Photo: Internet) Cryogenics, also known as cryopreservation, is the technique of freezing a dead body or body parts to protect them from decomposition. Proponents of cryogenics see it as a magical technology to bypass death and even reach immortality. They decided to freeze and preserve the body intact, hoping to wait until science developed enough to revive the dead body and cure whatever caused them to die before. . (Photo: Internet) To date, more than 350 dead people worldwide have been preserved at low temperatures at one of four facilities providing this service: two in the US (Alcor Life Extension Foundation, Arizona and Cryonics Institute, Michigan State); 1 in Russia (KrioRus company), and 1 in Portugal (also Alcor lab). About 1,000 people have signed up for the post-mortem resurrection service. In this list, there are famous figures such as Britney Spears, Simon Cowell, Larry King, Don Laughlin (a gambling business magnate in the US) or director Charles Matthau… How are cryogenics performed? Legally, deep freezing is only performed when the patient is dead. The ideal time to start a cryogenics procedure is about 2 minutes after the patient’s heart stops and no more than 15 minutes afterward. First, the body is gradually cooled with ice and injected with chemicals to reduce clotting. After the temperature drops to near 0°C, blood is drawn to be replaced with a solution intended to protect tissues and organs. (Photo: Internet) The technicians also injected the body with another solution to prevent ice crystals from forming, then continued to cool the body down to -130°C. As a final step, the body is moved to a container of liquid nitrogen. There, it will be cooled down to -196°C. Cost of cryogenics The fee that a person has to pay if they want to deep freeze the whole body at the Cryonics Institute is from about 35,000 USD (about 800 million VND). While if you do the procedure at KrioRus in Russia, it will cost you 37,600 USD (about 860 million VND). At Alcor, the cost of preserving a person is 220,000 USD (equivalent to 5 billion VND), if you want to save more, just preserve the brain for about 80,000 USD (approximately 1.8 billion VND). This cost does not include the annual maintenance fee, which means that the longer you keep it, the more money you have to spend. (Photo: Internet) chances of success Many scientists believe that the chance to revive a dead person is almost zero. Because the body’s organs, especially vital organs such as the heart, lungs, brain, and kidneys, must have been damaged when freeze. Until now, the damage that has occurred and resulted in death is irreversible. Due to the severe damage to internal organs and the brain, the law requires technical participants to be scientifically dead, which makes it almost impossible to revive a dead person. (Photo: Internet) Alcor doesn’t offer a clear technique to resurrect someone who’s been dead too long, or a technique under development in the future to bring the dead back to life. A very vague technology on Alcor’s website is described that they will use molecular nanotechnology with microscopic nano-sized robots that can replace damaged chromosomes and can restore individual cells. . It is worth mentioning that Alcor has not researched this technology, in fact they only trade in freezing and preserving the dead and no one is responsible for the patient’s promise to revive. Alcor’s main research is only on techniques to preserve the dead as best as possible. The prospect of resurrecting a frozen body has so far been quite remote and unrealistic. And many in the scientific community even consider this to be unethical.
