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.
It leads to cardiovascular disease (for example, stroke and heart attacks), [45] which, globally, is the most common cause of death. [46] Vessel ageing causes vascular remodelling and loss of arterial elasticity, and as a result, causes the stiffness of the vasculature. [44]
The uses for biomarkers of aging are ubiquitous and identifying a physical parameter of biological aging would allow humans to determine our true age, mortality, and morbidity. [10] The change in the physical biomarker should be proportional to the change in the age of the species.
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 primary sites of end-target organ damage following an increase in arterial stiffness are the heart, the brain (stroke, white matter hyperintensities (WMHs)), the placenta, and the kidneys (age-related loss of kidney function). [21] Firstly, stiffened arteries compromise the Windkessel effect of the arteries. [22]
The authors begin by seeking to characterize how professionals view the hallmarks of aging, including genomic instability caused by DNA damage; alterations to the epigenome that controls which genes are turned on and off; loss of healthy protein maintenance, known as proteostasis; exhaustion of stem cells; and the production of inflammatory ...

Cohorts for Heart and Aging Research in Genomic Epidemiology, abbreviated CHARGE, is a consortium formed to facilitate meta-analyses of genome-wide association studies of aging and cardiovascular traits, and the replication of genotype–phenotype associations identified in such studies.
