Why are people referring to alcoholism as a disease not a lifestyle choice?

Addiction= disease. Some people refer to alcoholism as death on the installment plan.
Alcoholics r Ill. There r genetic & chemical differences--one alcoholic told me if he went 2 a bar that advertised "all u can drink 4 $5.00" he'dsay give me $10.00 worth! 60% of alcoholics have an alcoholic parent.
