Lifestyle choices greatly influence lifespan, not genetics

A new study published in Nature Medicine shows that lifestyle and environmental factors significantly influence lifespan, contributing about 17% to longevity, while genetics account for less than 2%. This shifts the focus from genetic predisposition to personal choices. The research analyzed data from the UK Biobank, including health and lifestyle information from around 500,000 people. It found that smoking, socioeconomic status, and physical activity had the most impact on health and longevity. Interestingly, the study found no strong link between diet and biological aging, which contrasts with previous research. Limitations include the observational nature of the study and the reliance on self-reported dietary data.
