What is the telomere theory of aging?

In 1961, biologist Leonard Hayflick discovered that normal human cells have a limited capacity to divide before they stop replicating, a phenomenon known as the Hayflick limit. At the heart of this observation lies the telomere theory of aging, which offers a compelling explanation for how our cellular lifespan is regulated.

Can Telomeres Reverse Aging? The Science Behind Cellular Longevity

Telomeres, the protective caps on the ends of chromosomes, shorten with each cell division, a process long considered the biological clock of aging. This has led many to question: Can telomeres reverse aging? Emerging science suggests that while a full reversal of biological age is complex, strategies exist to lengthen telomeres and mitigate aging's effects.
