Longevity research explores biological age and new perspectives on aging

Recent advancements in longevity science are shifting the focus from chronological age to biological age. Biological age tests, which analyze blood markers and DNA methylation—such as the Horvath clock developed in 2013—aim to determine how quickly an individual's cells are aging. Experts note that a biological age higher than one's chronological age may indicate a higher risk of adverse health outcomes, while a lower biological age may suggest protection against such issues.

Beyond clinical metrics, new perspectives are emerging regarding the social and psychological aspects of aging. In the book “La vejez no existe: El arte de vivir la nueva longevidad,” Humberto Cadavid argues for a redefinition of aging. Rather than viewing it solely as a period of loss or decline, the work suggests viewing longevity as an opportunity for continuous learning, autonomy, and maintaining social connections. The discussion moves from merely extending lifespan to improving the quality of life and how individuals inhabit their later years.
