The Immortals

The Immortals, a science fiction novel by David Duncan published in 1960, explores the consequences of immortality through the fictional Y Hormone, which halts aging. The narrative follows Dr. Clarence Peccary, who grapples with the moral implications of his discovery alongside Roger Staghorn and a powerful computer named Humanac. As they predict a future dominated by the Atavars, a group that embodies the perils of eternal life, the story delves into themes of ambition, mortality, and the human condition, culminating in a confrontation that questions the value of life without risk or aspiration.
