Olbermann suffers from a mild case of coeliac disease, as well as restless legs syndrome. In August 1980, he also suffered a head injury while "leaping" onto the NYC subway. This head injury permanently upset his equilibrium, resulting in his avoidance of driving.
I"m trying to imagine that (after having it intermittently for decades only to have it stick in ON position after minor surgery.)
You just have to quit the wheat, barley and rye.
