Job, smoking, sleep, exercise bigger factors than genes in disease and early death: study

Nurture is more influential than nature when it comes to a number of major diseases and premature deaths, according to a new study.

Environmental factors are almost 10 times more important than genetic factors when it comes to a person’s risk of death from a number of serious diseases, according to one of the largest studies of its kind. Researchers have also said that many of the environmental risk factors for disease can be modified.

Living conditions are also important, including whether someone lives with a partner, their household income and whether people use an open fire for heating.
