Cryonics: The Science of Immortality? 

It is a science to save life by using temperatures so cold that a person beyond help by today’s medicine can be preserved for decades, even centuries, until some new medical technology in future can restore that person to full health. 

Cryonics is based on the belief that a human survives even within an inactive, badly damaged brain, provided the original encoding of memory, can be adequately inferred and reconstituted from what remains. 

Total death is the point at which all brain function ceases. Legal death occurs when the heart has stopped beating, but some cellular brain function remains. 

James Bedford, an American psychology professor at the University of California, is the first person whose body was cryopreserved after legal death and remains preserved at the Alcor Life Extension Foundation to the present day. 

As of 2014, about 250 bodies had been cryopreserved in the United States, and 1,500 people have made arrangements for cryopreservation of their corpses. 

As of now, there is no law in India to regulate cryonics. 

Cryonics is regarded with scepticism within the mainstream scientific community. It is generally viewed as a pseudoscience, and its practice has been characterised as quackery.
