But I'm thinking either he's a jock at a Big-Ten school where his real job is on the football field; or years from now he's going to wish he had challenged himself with a school or a set of courses that actually encouraged  the exercise of his cranial appendage.
    I should add a brief note, apologizing for my online absence. A book deadline, on the one hand; but on the other, a terrific trip to Greenland, Labrador and Newfoundland, about which I hope to post more soon.
