The Alcor Life Extension Foundation is a non-profit organization based in Scottsdale, Arizona, dedicated to the field of cryonics. Founded in 1972, Alcor aims to preserve individuals who have been declared legally dead through a process called cryopreservation, which involves cooling the body to very low temperatures to halt cellular decay. Alcor offers various membership plans and services, including whole-body and neurocryopreservation options. The organization conducts research to improve cryonics techniques and advocates for the potential of life extension through advanced medical technologies.
