Immortality is eternal life , the ability to live forever. [2] Some modern species may possess biological immortality.

In religious contexts, immortality is often stated to be one of the promises of God (or other deities) to human beings who show goodness or else follow divine law. What form an unending human life would take, or whether an immaterial soul exists and possesses immortality, has been a major point of focus of religion , as well as the subject of speculation, fantasy, and debate.

Life extension technologies promise a path to complete rejuvenation. Cryonics holds out the hope that the dead can be revived in the future, following sufficient medical advancements. While, as shown with creatures such as hydra and planarian worms , it is indeed possible for a creature to be biologically immortal , it is not known if it is possible for humans.
