Call it the Red Wine Syndrome. Take something that's known to be wildly destructive when taken in excess: something that can wreck your liver, destroy your family, create bloody mayhem on the highway and turn you into a pathetic, falling-down wretch. Then have some scientists announce that, taken in moderation , this thing can . . . prevent cancer!

If you're a drinker who's sick and tired of being scolded, you're going to be pretty excited about this news.
