A (currently non-standard) medical technique for attempting to prevent the permanent cessation of life in individuals on the brink of death. It involves the use of low temperatures to halt metabolic decay. A person who is cryonically suspended can not be revived by current medical technology. The freezing process does too much damage. What is accomplished is that once frozen the person's biological state does not change. The reason for performing a cryonic suspension is the belief that science, technology, and society will advance to the point where revival of the person is both possible and desirable.
