Introduction: aging vs. senescence vs. (bio)gerontology
Firstly, some definitions to avoid confusion: senescence is the biological aspect of aging; gerontology is the science of aging; biogerontology is to gerontology as senescence is to aging.
My intention is that this category will be dedicated strictly to the biological aspect of aging—including such biogerontological topics as abnormal senescence (e.g., progeria), aging-associated diseases (e.g., atherosclerosis), genera (e.g., Hydra), substances (e.g., telomerase), and phenomena (e.g., late-life mortality plateau)—but excluding such topics as the biogerontological community (e.g., life extension organizations, individual biogerontologists, aging journals, and history of biogerontology) and non-biological aging (e.g., retirement, ageism, gov't spending on treatment of hypertension, life expectancy rates across the world, aging offenders in jurisprudence, and old age in folklore). Please don't add unrelated topics. Everything Is Numbers (talk) 16:19, 24 September 2012 (UTC)
