Yeah, you've stopped eating ham sandwiches and sleeping next to your Miss Piggy stuffed animal (who doesn't?) out of fear of catching the swine's flu, but you're not the one who should be worried: the high-density, high-volume swine farms in the U.S. could get hit hard if somebody coughs on their pigs. Wait - pigs can catch swine flu too? Yeah, right Lisa. They must be some wonderful, magical animal.
