"As you can imagine, the study's discoveries are bountiful, but the most significant finding of all is that 'Alcoholism is a disorder of great destructive power.'

Together with cigarette smoking, alcoholism proves to be the #1 greatest cause of morbidity and death. And above a certain level, intelligence doesn't prevent the damage."
