Lifediners

Lifediners is a term used in discussions of longevity to describe individuals who seek or achieve significantly extended lifespans through a combination of medical, technological, and lifestyle strategies. In real-world discourse, lifediners may refer to participants in longevity programs or cohorts; in speculative fiction, the term designates characters who live for centuries or longer. The concept emphasizes life extension as both a biomedical goal and a social and ethical issue.

The term is a neologism rather than a formal medical category. It arose in online science communication and fiction in the 2010s and 2020s and is used variably. Some writers contrast lifediners with shorter-lifespan populations, while others apply it broadly to anyone who pursues substantial healthspan gains.

Practices associated with lifediners include evidence-based health optimization such as caloric restriction or dietary planning, regular physical activity, preventive medicine, sleep management, and stress reduction. Where available, lifediners also engage in emerging therapies such as regenerative medicine, senolytics, or gene-editing trials, alongside continuous health monitoring and personalized medicine guided by data and AI.

Ethical and social considerations are central to discussions of lifediners. Debates address access and equity, cost, potential overpopulation, intergenerational fairness, risk of premature adoption, and governance of emerging biotechnologies.
