that is associated with susceptibility to certain diseases and physiological processes. Nevertheless, blood type is only one small piece of the aging puzzle.
Genetics, physical activity, diet, sleep, smoking, alcohol consumption, environmental exposures, socioeconomic factors, and access to healthcare all play much larger and better-established roles in healthy aging and longevity.
As research continues, scientists may better understand whether blood type has a meaningful role in the mechanisms of aging—or whether the observed associations are primarily related to specific diseases rather than aging itself.
