According to the study, brainy men were also more likely to remain physically independent as they age.
In the study, clever men showed a 1.1lb rise in lower back strength, a 1cm increase in jumping height, 1.5lb increase in hand-grip strength, 3.7 percent improved balance, and could do 1.1 more chair-rises in 30 seconds.
Rikke Hodal Meincke of the University of Copenhagen said that the better the results were of midlife tests, the greater was the chance of avoiding a decrease in physical performance in old age.
