Drinking on St. Patrick's Day got so out of hand in Ireland at one point that all bars were ordered closed on March 17, but that was repealed in the 1970s. Today, some revelers raise a pint of stout and wish their companions, "Slainté!" – the Irish word, pronounced SLAN-cha, for "health." Guinness beer, as it turns out, may be good for your health. At a conference of the American Heart Association in 2003, researchers from the University of Wisconsin reported that the frothy stout may be as effective as daily aspirin in reducing blood clots that cause heart attacks.
