Men with lean physiques at age 18 have a lower chance of dying from cancer later in life than those who are obese at that age, a study of Harvard alumni suggests.

Men with the lowest body mass index at age 18 were 35 percent less likely to die from cancer than those with the highest BMIs, according to the study by British and American researchers. The findings, published today in the Annals of Oncology, also showed that smoking and physical activity as a young adult didn’t affect results.
