The U.S. Department of Agriculture, in a 2005 review of 50 case studies, has revealed that generally, moderate beer drinker lives longer. Since one or two drinks a day, lowers the rate of heart diseases, strokes and diabetes, the study estimates that this prevents thousands of deaths in a year. These benefits are applicable throughout the world, as an earlier study in Europe believed that if the Europeans stopped drinking, the life expectancy might come down by at least two years.
