Alcor Life Extension runs a one-of-a-kind freezing clinic, and it's surprising that many people - including such famous personalities as PayPal co-founder Peter Thiel - are actually spending hundreds of thousands of dollars to maintain their bodies in it after death.

The idea of ​​waking up in the future may sound like a sci-fi movie or novel, but through cryonics, organizations like Alcor are trying to do the same in reality.

Max Moore, the former chief executive of Alcor, believes people can be saved from death. "Our view is that when we call someone dead it's a bit arbitrary," he says.

Perhaps most surprisingly, Alcor is not the only cryogenic clinic that preserves cadavers for future revival attempts.

What is freezing?

How is the corpse preserved forever?

The cryonics technology maintains a low temperature of a newly dead cadaver or a severed head.

In order to differentiate between cryogenics and storing the corpse at a low temperature, which are called “cryogenics,” it must be known that in cryogenics, the body is stored at temperatures below -130 degrees Celsius in the hope that some advanced technology or nanotechnology Able to bring a person back to life in the future, "according to experts."

To protect body parts from any damage during freezing and storage, cryopreservation practitioners use cryoprotectants and cryopreservation, which can be considered techniques similar to those used to prevent body parts donated by an organ donor from rotting after death.

For those who registered in Cryonics, the emergency cryogenic response team takes control of the body after medically declaring death, as they immerse the body in ice and ensure that oxygen and blood reach the brain, and the team injects heparin into the body so that your blood does not clot during Transfer it to the freezing facility from the place of death.

In a freezing facility, the body is placed on a machine that circulates the blood and preserves oxygen, similar to a heart-lung bypass machine. A crystal solution is pumped into the body, which is a protective antifreeze and acts like an antifreeze to prevent body tissues from turning into ice crystals during freezing. This is essential Because when your body freezes, ice crystals can rupture cells and cause tissue and organ damage.

The body is then slowly cooled to about -320°C using a liquid nitrogen vapor chamber, and once it is cool enough the body is transferred to a tank of liquid nitrogen, where it is stored at about -320.8°C in an inverted position.

The goal here is to prevent any damage to the brain even if there is a leak during the time the body is stored in containers of liquid nitrogen, and cryogenics say the cells are believed to remain in hibernation.

Can refrigerants really make people immortal?

Although famous personalities such as Paris Hilton, Peter Thiel, Steve Aoki, Robert Miller, and many others aspire to cryopreservation, it is a controversial topic among the scientific community.

The people who advocate cryogenics consider this technology to be a way to beat death, but on the other hand there are scientists who claim that cryoscience is nothing but pseudoscience, giving people false hope in the name of technology.

Dennis Kowalski, president of the Cryogonics Institute in Michigan, believes that the freezing technology may sound like science fiction, but it is ultimately an optimistic technology.

"You have nothing to lose, everything to gain other than some life insurance money, and for me, it's worth it," he says. Kowalski himself, his wife and children also enrolled in posthumous cryopreservation.

The different views of researchers and cryopreservation experts regarding cryopreservation can be understood by examining a court case that emerged in the United Kingdom. In November 2016, a 14-year-old British girl referred to as “JS” died of a rare species. of cancer, and before she died she left a will that said her last wish was to keep her body cryopreserved until she could be resurrected in the future.

"I don't want to be buried underground, I want to live longer, and I believe that in the future they may find a cure for my cancer and wake me up, I want to have this opportunity, this is my wish," the will read.

JS's mother wanted her daughter's last wish to come true, but her estranged father opposed it. Freezing.

In response to the issue, cryobiologist Ramon Risco told The Guardian that while cryosections is currently an incredible concept - just like "test-tube babies" or space travel - it should not be considered impossible.

He believes that within 5 to 10 years experts will likely have made sufficient progress to revive the small mammal after maintaining liquid nitrogen.

"It is very dangerous to say that anything is impossible in science or technology in the 21st century," he said. "If you are looking for the truth, why put up barriers?"

Risco also argued that many scientists oppose the science of freezing, because supporting this idea may jeopardize their careers. In fact, it can get them expelled from their scientific community."

Clive Quinn, eminent professor of neuroscience at King's College London, was one of those who opposed the Supreme Court's decision to allow cryopreservation of girl JS.

Prof Quinn argued that "morally it is very complicated, she may have got what she wished for in her will, but others may now be deceived on the pretense that someone did."

The famous cosmologist Martin Rees has also raised concerns about the practical and ethical applicability of issues related to freezing, and considers that freeze enthusiasts are not believable, because the claims they make are "ridiculous."

Currently, there is no scientific evidence that fully agrees or explains the possibility of new life in the future through freezing technology.

When it comes to legal issues, US law does not treat cryopreservation and organ donation as two different things.

According to the Uniform Donation Act (UAGA), the practices of companies like Cryonics are similar to scientific experiments, in which people willingly donate their bodies and organs. Resuscitate future clients after they have undergone cryopreservation.

Interesting facts about cryosurgery

Instead of burial or cremation after death, thousands of people from all over the world have been involved in cryopreservation, yet this is not the only amazing fact about cryopreservation.

On January 12, 1967, the American psychologist Dr. James Bedford underwent a cryopreservation operation shortly after his death, and was the first person in the world to decide to do so, and his frozen body is still at Alcor Life Extension in Arizona.

Anyone can have their entire body cryopreserved at Alcor for $200,000, or just their head for just $80,000. Surprisingly, the Cryonics Institute only charges $28,000 for cryopreservation.

When a representative from Alcor was asked about this huge price gap, he revealed that a large portion of the fees are being spent to support the Patient Care Trust Fund that funds the maintenance of the facilities.

American baseball player Ted Williams has also been cryopreserved at Alcor, where the cryo-science idea has become very popular with celebrities, for example, DJ Steve Aoki on the Kryonics program, but also on Alcor.

The number of corpses stored in Alcor has increased at an average rate of 8% annually. The oldest corpse stored is of a 101-year-old woman, and the youngest is only two years old.

KrioRus, a freezing company in Russia, also allows its customers to keep their pets refrigerated.
