What affects us more? Nature or nurture?

Nice News -  It’s an age-old question: Does nature or nurture impact us more? When it comes to our health, it may be the latter. A new study suggests that lifestyle and living conditions affect aging significantly more than genetics. Researchers with the University of Oxford examined data from nearly half a million biobank participants, assessing the influence of 164 environmental measures and genetic risk scores for 22 major diseases. The team also used a novel aging measure, or “aging clock,” that looks at blood proteins to evaluate the speed at which people age.
​
They found that environmental factors accounted for 17% of the variation in risk of death, with smoking, socioeconomic status, physical activity, and living conditions impacting mortality and biological aging the most. Genetic predisposition, on the other hand, explained less than 2% of that risk. And of the 25 associated environmental factors the study identified, 23 are modifiable.
