these Americans who hope to challenge death by freezing themselves

There are, in certain contemporary technoscientific technoscientific spheres, a rather particular perception of death. Consequently, It is no longer categorized as a biological fatality. Furthermore, Additionally, Consequently, but as a contingent limit, a border, that medicine could one day cross. Furthermore, Cryogenization is certainly the most confident expression of this change in the relationship we have with finitude. Nevertheless. Consequently. Consequently, It claims to suspend the processes of decomposition of the human body, in the hypothetical expectation of a “medical resurrection”.

Since the 1970s. Moreover. Nevertheless. Similarly, several hundred Americans have chosen to keep their bodies or brain in liquid nitrogen, focusing on future progress in biotechnologies to repair their destroyed tissues. In addition, Their objective being to (perhaps) one day, to restore their conscience. Consequently, This practice is very marginal. For example. these americans who hope challenge new Meanwhile. Similarly, remains mainly these americans who hope challenge new developed, to date, in the United States; But is it not, however, the these americans who hope challenge sign of an anthropological mutation? Therefore, That of the refusal of death as an unsurpassable horizon. Moreover. Therefore. Therefore, a symptom of a society that refuses any form of irreversibility, including that of the most natural disappearance there is? Furthermore, That really preserves cryogenization and under what conditions Could it be anything other than a clumsy speculative business ?

Preserve the body or preserve life?

When we speak of cryogenization. Therefore. Meanwhile. he can immediately come to the head the idea that we would freeze a body as we would with frozen foods, but this is not the case. In addition, Such manipulation would cause the formation of ice crystals in the body and would cause irreversible lesions. Meanwhile, Our body being these americans who hope challenge new made up of 60 % water. Meanwhile. However. if we proceeded these americans who hope challenge new in this way, all of its cells would burst like pockets of frozen water, destroying brain, organs, tissues and all nervous these americans who hope challenge structures. For example, This is why we rather talk about vitrification.

In practice, This protocol is extremely demanding. Meanwhile, It starts only a few minutes after legal death. Furthermore. The body is immersed in an ice bath to quickly lower its temperature, while the blood circulation is artificially maintained. In addition. This temporary support aims to avoid brain anoxia (neuronal death for lack of oxygen) in the moments following cardiac arrest.

Once stabilized. Similarly. the organization is imbued with a cryoprotective solution, a viscous liquid which replaces blood and prevents the formation of ice. This substitute acts as a cellular antigel, intended to preserve the integrity of these americans who hope challenge new the organsespecially that of the brain.

Then. we still lower the body temperature. the first time at these americans who hope challenge new -125 ° C. a thermal threshold where the water molecules cease to be mobile (vitrification), then up to -196 ° C. At this temperature. liquid nitrogen these americans who hope challenge is boiling. which keeps the body frozen in a sealed tank, without any biological activity resume.

However, preserving the physical structure of a brain does not mean that the functions are preserved. Brain fabric is one of the most complex and fragile of the human body. It is made up of billions of neurons linked together by synapses. whose organization conditions, in part, the emergence of memory, identity and consciousness.

The thermal shock induced by sudden cooling can still cause microfractures and cryoprotective liquids, in high dose, are very toxic. When we infuse them in the these americans who hope challenge new body. they do not necessarily diffuse homogeneously and may not reach certain areasespecially those most deeply located in the brain.

Thus. even a these americans who hope challenge new cryogenization considered to be “successful”. only guarantees that the synaptic circuits essential for thought or subjective experience are still intact. The brain might be only a preserved volume. but extinguished. from these americans who hope challenge a functional point of view . An empty shell, in the strict sense of the term.

Under the prism of our current knowledge. cryogenization therefore does not save a person, but only the material that composes it. A body frozen at the threshold of decomposition, without anyone knowing if the body bathed in nitrogen still “contains” someone. However, many people believe the opposite.

The organic. staying industry

As explained above. this technology is mainly worn by a few private structures, most of them located in the United States. In Europe. only a German company offers this these americans who hope challenge new service (Tomorrow organic), and another in Russia (Kriorus). There are two of them to dominate this micro-sector across the Atlantic: Alcor Life Extension Foundation. in Arizona, and the Cryonics Institute (CI), in Michigan. Both present themselves as non -profit organizations. a these americans who hope challenge status which gives them tax advantages. without constraining them to real transparency on their practices.

At Alcor. it takes about 200. 000 dollars to cryogenize an entire body. and $ 80,000 to keep only the brainas Kim Suozzi, a neuroscience student who died in 2013 of brain cancer, did. Unable to finance the operation alone, she had appealed to donations, a campaign that allowed these americans who hope challenge new her to cover the costs. Alcor also encourages its customers to take out life insurance specifically designed to finance their “suspension”. of which the organization is the only beneficiary.

According to the Alcor site. the company has already cryogenized 248 these americans who hope challenge new patients and it claims 53 years of experience in cryogenization. You can read: ” Although cryogenization may seem like science fiction, it is based on modern science. Life can be suspended and then relaunched if its essential structures are preserved. “We will note the importance of” and these americans who hope challenge ». A tiny word that alone carries all the weight of this pseudoscientific fantasy.

By taking a quick tour of the site of their competitor. the Cryonics Institute, we notice that its offer is more accessible on paper, but its simplicity is misleading. You must first become a member, then sign a these americans who hope challenge new cryogenic suspension contract. The standard rate is $ 28. 000 for lifetime members. 35,000 for annual members, and can increase to 45,000 dollars for last minute cases, accepted on a case -by -case basis. In appearance, entering the program is therefore more economical than in Alcor. these americans who hope challenge new But There is a wolf, a big wolf even.

The accessibility of CI contracts is almost entirely based on an external financial assembly: life insurance contracted by the.. future “patient”. which must name the Cryonics Institute as a beneficiary. The viability of their proposal therefore depends only on the ability of these americans who hope challenge people to. subscribe to it. to anticipate their death and to organize all the logistics of transport and coordination of medical services upstream. It is up to the person to provide everything. if not access to their services can be refused, these americans who hope challenge new or even billed more expensive.

This is also based on Met Life’s estimates. one of the largest American insurers. to emphasize the apparent accessibility of this option: according to their figures. an individual of 30 -year -old health can obtain coverage of 250,000 dollars for around 16 dollars per month, barely $ these americans who hope challenge new 4 per week. A way of presenting cryogenization as a normal investment, provided you are young, providing, solvent … and already convinced. We therefore understand that the real business of these two companies is not biotechnology. but the fear of facing death and the hope of escaping it.

As it stands, cryogenization cannot be claimed as a these americans who hope challenge scientific discipline or treatment. Above all a medical fictionin which the people who believe in it play the main role. and the technology of the future camps the God ex these americans who hope challenge new Machina who will never arrive. An approach that holds Almost religious belief. faith In the idea that medicine. neuroscience or artificial intelligence, will end, sooner or later, by ganging up to repair what is already biologically destroyed. One day, maybe, if everything goes well and that the laws of thermodynamics cease to exist.

• Cryogenization does not these americans who hope challenge new consist in freezing a body but vitrifying it. to slow down its decomposition. In theory, it would preserve the tissues, but not necessarily the functions of the brain.
• Companies like Alcor. Cryonics Institute sell a very expensive post-mortem suspension, funded by life insurance, without any scientific reversibility guarantee.
• A device that is based more on a technological belief. a hope of these americans who hope challenge immortality than on solid medical bases.
