阅读理解    One of the most debated issues about alcohol consumption has been the consistent finding that those who don't drink tend to die sooner than those who do.The standard Alcoholics Anonymous explanation for this finding is this：many of those who give up alcohol are actually former hard­core drunks who had already brought health problems associated with drinking.    But a new paper suggests that abstaining(戒除)from alcohol does tend to increase one's risk of dying，even when you leave former problem drinkers out.The most shocking part—abstainers'(禁酒者)mortality rates(死亡率)are higher than those of heavy drinkers.    Moderate(适度的)drinking，which is defined as one to three drinks per day，is associated with the lowest mortality rates.Moderate alcohol use is thought to improve heart health，circulation and sociability，which can be important because people who are cut off don't have as many family members and friends who can notice and help treat health problems.    But why would abstaining from alcohol lead to a shorter life？It's true that those who abstain from alcohol tend to be from lower socioeconomic classes，since drinking can be expensive.And people of lower socioeconomic status have more life stressors(压力因素)．    Though heavy drinking is associated with higher risk for many diseases，heavy drinkers are less likely to die than don't drink. One important reason is that alcohol strengthens social interactions，and social interactions are vital for maintaining mental and physical health.Nondrinkers show greater signs of depression.    The authors of the new paper are careful to note that even if drinking is associated with a longer life，it can be dangerous：it can affect your memory severely and it can lead to falls and other troubles that can affect your life.There's also the dependency issue：if you become addicted to alcohol，you may spend a long time trying to get off the bottle. （1） What can we know from the Alcoholics Anonymous explanation and the new paper?
