TL;DR: A brand new examine from Oxford Inhabitants Well being discovered that way of life and environmental components have a a lot larger influence on well being and getting older than genetics. Smoking, bodily exercise, socioeconomic standing, and residing situations are essentially the most important influences on longevity.
