Five Minutes: Man with Furrowed Brow1

1 "Furrow": I assume that's one of those words that started out as a metaphor — likening the wrinkles of a brow to the furrows of a field — but then the metaphorical meaning became primary and the original became secondary — people don't talk much about field furrows these days (I suppose a consequence of our shift away from the agrarian lifestyle). And it's one of those words that almost always travels in a pair: one rarely hears the word "furrow" except in the company of "brow".
