The Biology of Longevity: Cellular Senescence and Autophagy

Aging is not simply the passage of time; it is a highly specific biological process characterized by the accumulation of cellular damage and the decline of our intrinsic repair mechanisms. Two of the most significant factors in this process are the build-up of cellular senescence (often termed "zombie cells") and the failure of autophagy (the body's cellular recycling program).

By understanding these two antagonistic forces—senescence which drives aging, and autophagy which drives rejuvenation—we can implement targeted lifestyle protocols to profoundly influence our biological age and extend our healthspan.
