a winnar is you!
both of my parents are alcoholics. both have been or are addicted to other drugs as well. if asked, i will tell you that i am an alcoholic or a drug addict waiting to happen. what keeps it from happening? my will. i have chosen not to drink, nor to use recreational drugs. so, the "gene" in me lies dormant. at least where chemical addiction is concerned. choose not to drink, and there, youve conquered alcoholism.
you can find yourself addicted to anything. a sport, sex, a game, a routine, the gym, etc, etc. its just that chemical addictions tend to be quite a bit more illegal and thusly, carry quite a bit more of a social stigma.
