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.
Biogerontologists have continued efforts to find and validate biomarkers of aging, but success thus far has been limited. Levels of CD4 and CD8 memory T cells and naive T cells have been used to give good predictions of the expected lifespan of middle-aged mice. [5] Advances in big data analysis allowed for the new types of "aging clocks" to be ...

A heart healthy lifestyle that follows the Life Essential 8 guidelines that include a quality diet and regular exercise can help slow biological aging and improve cardiovascular health ...
GeroScience (formerly Age; Journal of the American Aging Association) is a scientific journal focused on the biology of aging and on mechanistic studies using clinically relevant models of aging and chronic age-related diseases. The journal also publishes articles on health-related aspects of human aging, including biomarkers of aging ...
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.
According to this theory, life span development has multiple trajectories (positive, negative, stable) and causes (biological, psychological, social, and cultural). Individual variation is a hallmark of this theory – not all individuals develop and age at the same rate and in the same manner. [15] Bronfenbrenner's ecological theory
