Natural and cultural longevity zones from an anthropological and geographical viewpoint

There are natural and cultural variables that have an impact on the longevity of older adults. In the case of the former, it is necessary to know and territorialize them, and in the case of the latter, it is necessary to understand them through the analysis of customs and lifestyles. The zones of natural longevity, for this analysis, are those in which low levels of ionizing and ultraviolet radiation converge, as well as the presence of water containing deuterium oxide among its components. To address the cultural longevity zones, an ethnography was carried out in which it was observed that both the consumption of heavy water and the lifestyles generated by the production of coffee and sugar cane prolong life and good old age in the town of El Espinal, municipality of Naolinco, Veracruz.
