As we age, cellular damage increases and cells’ ability to repair themselves diminishes, leading to reduced function and increasing risk of disease and death. Aging occurs across all living organisms–humans, animals and fungi alike. Some organisms age faster than others.
Aging is a complex process affecting multiple body systems simultaneously. Beginning at cellular level and progressing to organ and tissue level. Our tissues consist of groups of similar cells which perform specific functions; when these tissues come together they form organs held together by connective tissue; during aging this connective tissue becomes worn out and changes at different rates for different organs in our bodies.
Skin changes are an indicator of the aging process. With age comes decreased elasticity and thinner outer skin layers; this can result in wrinkles and sagging skin as well as less flexible, less flexible skin that is more prone to bruising. As this process continues, blood vessels also decline; waste products accumulate within tissues while lipofuscin accumulates in these same tissues – all hallmarks of an aging process.
Signs of the aging process include changes in taste and smell, slower digestion, difficulty sleeping at night and muscle weakness due to loss of strength in bones.
