Can I donate a dead body to cryogenic freezing?
You do not MEAN **cryogenics**, which is low temperature physics: “The branches of physics and engineering that involve the study of very low temperatures, how to produce them, and how materials behave at those temperatures”. By contrast, cryonics is “The emerging medical technology of cryopreserving humans and animals with the intention of future revival.” What you MEAN is “Can I donate a body to **cryonic** freezing” Although people cannot be cryopreserved unless they are legally dead, cryonicists do not view legal death as being the same as death in an ultimate sense. As people in cryonics often say, “death is a process, not an event”. Decomposition, autolysis and brain ischemia are processes that gradually destroy the brain after the declaration of legal death. The longer the time which passes after legal death before which low temperature and anti-ischemic processes are applied, the less brain structure is preserved. When brain tissue has been so decomposed or destroyed that it is
