Understanding Aging Mechanisms

Aging is a complex biological process characterized by intrinsic mortality, which significantly increases the likelihood of diseases as one ages. Researchers identify 'aging hallmarks' such as cell senescence and genomic instability that contribute to the biological aging process. For instance, as cells divide, the protective telomeres at the end of chromosomes shorten, which is a hallmark of aging leading to cellular dysfunction. Understanding these mechanisms allows scientists to examine potential interventions to slow down aging and improve overall health in later years.
