Cryonics:  Science Behind Immortality

At this time 200 Frozen Heads and Bodies Await Revival at This Arizona Cryonics Facility

Cryonics, as a concept, can be traced back to the early 20th century

The idea is simple but profound: to prevent cellular damage and decay, bodies are cooled to extremely low temperatures

Temperature typically around -196 degrees Celsius (-321 degrees Fahrenheit), using liquid nitrogen

The cryonics procedure begins with a patient's legal death being declared by a medical professional.

In this process The patient's body is cooled down and blood is replaced with a cryoprotectant solution to prevent ice formation within the cells.
