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.

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.
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.
This is an accepted version of this page This is the latest accepted revision, reviewed on 2 February 2025. Biological process of getting older This article is about ageing specifically in humans. For the ageing of whole organisms including animals, see Senescence. For other uses, see Ageing (disambiguation).

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 ...
David Gems is a British geneticist who studies the biology and genetics of ageing (biogerontology). He is Professor of Biogerontology at the Research Department of Genetics, Evolution and Environment, University College London and he is a co-founder and Research Director of the UCL Institute of Healthy Ageing.
In biogerontology, the disposable soma theory of aging states that organisms age due to an evolutionary trade-off between growth, reproduction, and DNA repair maintenance. [1] Formulated by British biologist Thomas Kirkwood , the disposable soma theory explains that an organism only has a limited amount of resources that it can allocate to its ...
