This isn't a headline, but it's become a byword in our household. Some years ago I received in the mail, unsolicited, a package of animal fact cards, complete with stupendous offer to buy more, plus a binder for them. I passed on the offer, but read the cards. The one for the polar bear read, in part: "The polar bear's sense of smell is so sensitive that it can smell a dead whale twenty miles away." To which our rejoinder, between gusts of laughter, was "WHO COULDN'T?"
