问题 What has recent research found about drinking?
  
Researchers have discovered a link between drinking and thinking. A moderate amount of alcohol may help us keep our mental abilities as we age. Brain scans show alcohol abuse kills brain cells. But little is known about the effects of life-long drinking. So moderate drinkers may want to toast new findings from researchers at Duke, and Indiana Universities. Dr. Joe Christian of Indiana Universities says men who have one or two drinks each day retain slightly stronger comprehension skills than the non-drinker or the heavy drinker. The doctor and his colleagues gave mental tests to nearly 4000 male twins between the ages of 66 and 76. The moderate drinkers had slightly better reasoning ability than their brothers who drink more or less. Other studies have found that alcohol in moderation can help the heart. But alcohol abuse can cause bone loss and other health problems. This study was presented at an alcoholism meeting in San Antonio.
