100+ people have been Cryogenically frozen and are to be Resurrected

The Alcor Life Extensions Foundation, located just outside a posh Phoenix suburb, is home to 146 bodies that were frozen at the time of death. The human body may be frozen and kept at low temperatures indefinitely, preventing it from decaying as it would normally after death.

Those that wanted to be frozen at death were most likely from affluent families, as the procedure alone can cost up to $200,000. They must also have sufficient ongoing financial support to stay frozen indefinitely.

Although resurrecting a human body can seem like a far-fetched futuristic dream, researchers at 21st Century Medicine in California succeeded in defrosting a rabbit brain in an almost perfect state from a cryogenic state in 2016.

Do You Know: The frozen bodies of the optimistic are lined up in three cryogenic facilities around the world: Alcor, the Cryonics Institute in Michigan, and Russia's KrioRus.

How are people Cryogenically frozen?

When the heart ceases beating and you are declared "legally dead," the facility's emergency management team goes into action. The team stabilizes the body by providing enough oxygen and blood to your brain to maintain minimal function before you can be transferred to the suspension facility. To keep your blood from clotting during the flight, your body is wrapped in ice and injected with heparin (an anticoagulant). A medical team is waiting for the body to arrive at the cryonics facility.

After you've been moved, the "freezing" starts. Since the water inside their cells would freeze if they were placed in a vat of liquid nitrogen, cryonics facilities are unable to do so. Water spreads as it freezes, which will cause the cells to shatter. The cryonics team must first strip the water from your cells and substitute it with a glycerol-based chemical mixture known as a cryoprotectant, which functions as a human antifreeze. The objective is to prevent ice crystals from forming in the organs and tissues at extremely low temperatures. Vitrification is the name for this operation.

After the cryoprotectant has replaced the water in your body, the vitrification process is completed by cooling your body on a bed of dry ice until it reaches -130 C. The next move is to position your body in an individual tub, which is then put in a large metal tank filled with liquid nitrogen at about -196 degrees Celsius. Your body is stored head down, if the tank ever leaks, the brain will be submerged in the freezing liquid.
