I met two decades ago a former prisoner of war in Siberia. He was old and sick, in a hospital, problems at the liver. He told to doctors that, during 11 years of his imprisonment time he used to drink several liters of vodka daily, sometimes more than 3-4, because it was very cold in winter, temperatures up to - 50 Celsius degrees. He was the weakest drunk contester, the Russians drink 4-5 liters daily, in winter time. So, 12 bottles per year in capita is no big deal, compared to old times. Heh, heh...
