aging and senescence
Aging refers to the process of growing older and experiencing changes over time, both physically and mentally. It involves a gradual decline in various bodily functions and an increased susceptibility to diseases. Senescence, on the other hand, refers to the biological state when cells, tissues, or organisms display irreversible changes and lose their ability to function optimally. It is characterized by a decline in biological functions, reduced ability to repair damage, and an increased vulnerability to age-related diseases.
