Why Medical Experts Are Changing Their Mind About Lifespan: What the Latest Research Reveals Lifespan — the maximum length of time an organism can live — has long fascinated scientists, policymakers, and the public. For decades, medical experts assumed that human lifespan was relatively fixed, capped sometime in the 120s, constrained largely by genetics and unchangeable biological limits. However, groundbreaking research published over the past decade is reshaping this long-held belief. What’s driving this shift in thinking, and what does it mean for the future of health and longevity? ### The Traditional View: Lifespan Is Fixed For much of the 20th century, medical science accepted a conservative lifespan ceiling of around 110–115 years. Aging was seen as an inevitable decline driven by cellular wear and tear, DNA damage, and the accumulation of molecular mistakes over time. Treatments focused on managing age-related diseases — such as heart disease, cancer, and Alzheimer’s — rather than extending life itself.
