Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle.
: the state of being old : the process of becoming old or aging. The life of a mosquito—and this may be the only good news about the insect—is brutal and short. Roughly one in five die every day, and not from senescence. Gary Taubes.
Senescence is a process in which cells reach permanent growth arrest without the death of cells as the whole cell division process comes to a halt. It can either occur at the cellular level or senescence of the whole organism can take place.

Senescence is of three main types: replicative senescence, associated with telomere attrition, oncogene-induced senescence and therapy-induced premature senescence (Mikula-Pietrasik et al., 2020). Replicative senescence in human fibroblasts is a result of telomere shortening over cell divisions to a degree at which chromosome ends become ...
