Slowed Gompertzian ageing in long-lived C. elegans results from expansion of decrepitude, not decelerated ageing.
Longevity research challenges itself: long-lived animals may simply stay active longer rather than aging more slowly, reshaping how we interpret aging studies.
By analyzing mortality kinetics in long-lived C. elegans, this Nature Communications paper shows that these animals live longer due to prolonged decrepitude rather than decelerated biological aging, raising important questions about whether current longevity interventions in model organisms translate to true healthspan extension. This conceptually challenges the interpretation of longevity research in model organisms.
