#longevity

• abhaz - A person belonging to the native population of Abkhazia or originating from there; as an adjective, it designates everything pertaining to this region or its culture. In 20th-century global gerontology and medical anthropology studies, the Abkhaz population became a major research subject due to an unusually high index of active longevity, with researchers analyzing the local diet, genetic factors, and rural lifestyle to understand the secrets of delayed cellular aging.
• abii - A historical and mythological term taken from ancient Homeric texts and old geographies, sometimes used in early European medical and anthropological treatises to denote a Scythian nomadic tribe north of the Danube, described as living in complete asceticism, abstinence, and holding a strict lacto-vegetarian diet. In 19th-century medical hygiene texts, they were cited as a historical example of extreme longevity achieved through dietary moderation, lack of vices, and pathological isolation from urban epidemics.
