Experimental cryonics: Paul Segall in his garage laboratory in Berkeley, California, with his family and Miles, a beagle. Segall replaced Miles' blood with a substitute before cooling him to 37.4 degrees & disconnecting a heart lung machine. After 15 minutes, during which Miles' pulse, breathing & circulation had ceased, the dog was warmed, its blood returned & Miles was restored to health. Human cryonics clients are frozen & preserved in liquid nitrogen to await the advances in medical science that a future thaw might bring about. However, conventional cryobiology methods for freezing organs are plagued by problems of intracellular ice formation, which destroys cells. Cryonics is a speculative life support technology that seeks to preserve human life in a state that will be viable and treatable by future medicine. MODEL RELEASED 1987..
