How Did You Know You Had a Genetic Predisposition to Alcoholism?

When i went to harvard, they wouldn't let us let our research subjects leave until their blood alcohol level was at point o two. And then we had to include half women. We couldn't study women, because if your mother was alcoholic, you might have fedal alcohol cindrome. And basically what happened is, every single research psychologist stopped studying the response to alcohol because it became impossible. It's just alcoholism, right? It's like the fifth leading cause of death or some damned thing. I don't like that o. That's clearly pushes yor button, no doubt about it. Well, but i can see the origina in the in the ethics community.
