Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
This phenomenon is not only seen in yeast, but has also been seen in aging worms, during aging of human diploid primary fibroblasts, and in senescent human cells. In human primary fibroblasts, reduced synthesis of new histones was seen to be a consequence of shortened telomeres that activate the DNA damage response. Loss of core histones may be ...

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.
2013 The pan-tissue Epigenetic clock is a molecular biomarker by Steve Horvath that facilitates the measurement of the age of all human tissues based on cytosine methylation. [85] 2013 The scientific journal Cell published the article "The Hallmarks of Aging", that was translated to several languages and determined the directions of many ...
Organisms- As individuals age, their social networks begin to decline. Only thing remaining is the contacts for the most important social functions. Cognitive deterioration due to aging and loss of support systems leads to more declines in old age. [5] Social groups- A decline in social groups mimics the declines associated with the aging ...
