Today, the quest for immortality continues. Through cryogenics, freshly deceased persons or animals are frozen, their blood replaced with “medical-grade antifreeze” to prevent ice crystals from destroying cells. So, the idea goes, once medical technology is able to heal whatever caused their deaths, these creatures can be thawed, healed, and restored to life, possibly with additional enhancements. This approach assumes, among other things, that life and memory can be repaired if the body is repaired and the heart restarted.
