aging biology

Aging biology studies how our bodies change over time at the molecular, cellular, and systemic levels. It involves processes like DNA damage, cell wear and tear, decreased ability to repair tissues, and accumulation of waste products. These changes slow down bodily functions, reduce resilience, and increase vulnerability to diseases. Factors like genetics, lifestyle, and environment influence aging. Understanding these mechanisms helps develop ways to promote healthier aging, prevent age-related diseases, and possibly extend lifespan.
