Good news for everyone out there who's been called a "meathead" or a "doofus" or a "Jersey boy" or a "oxbrain" or a "big dumb galoot" simply because you enjoy lifting weights at the gymnasium: modern research shows that all types of exercise "ward off a host of cognitive impairments and enhances brainpower all life long." Which is good, because everything else designed to prevent you from being fat will, sadly, also make you dumb.
