As a pioneering biotech startup CEO attempting to achieve the first FDA-approved drug that extends healthy human lifespans, Celine Halioua bets on the belief that aging is not an inevitability, but a “tunable” system that can be optimized, using dogs as her first case study. Meanwhile, 87-year-old widower George Betke and his senior rescue dog face the challenges of aging together in their active senior community in Maine. Interweaving this emotional journey with interviews from world-leading longevity scientists and bioethicists, THE A-WORD: THE FUTURE OF AGING provides provocative scientific insights and questions whether the true goal of longevity science is to add years to life, or life to years.
