TL;DR: A brand new examine from Oxford Inhabitants Well being discovered that way of life and environmental elements have a a lot larger influence on well being and growing older than genetics. Smoking, bodily exercise, socioeconomic standing, and dwelling circumstances are probably the most vital influences on longevity. The examine highlights that almost all of those elements are modifiable, that means you could have the facility to enhance your well being and lifespan by way of acutely aware selections.
