Longevity is a scientific field that aims to optimize both chronological and biological age so that people can live as long as possible with fewer illnesses, more energy, and sustained mental sharpness.1
This field brings together multiple disciplines such as genetics, epigenetics, nutrition science, exercise physiology, psychology, and environmental sciences. The core goal is not only to extend lifespan, but to increase \"healthy years\".1,2
Researchers such as David Sinclair and Valter Longo emphasize that aging should be approached not merely as a chronological process, but as a biological phenomenon studied through cellular and molecular mechanisms.
