Fitter = Smarter
Research suggests that adolescent physically fit men tend to be more intelligent than their non-athletic counterparts.
Animal studies have long shown a link between physical activity and better memory. In humans, aerobic exercise can boost cognitive function in old people. Scientists found that of 1+ million men enlisted for military service @ 18, cardiovascular fitness, not muscle strength, was associated with overall intelligence (in the Swedish army). Physical fitness at 18 also foreshadowed greater academic achievement later in life for the public in general. Even among the twin pairs, the fitter brother tended to be the smarter.
