My mother tells me the story of her cousin or uncle or some such relation who was an alcoholic and often appeared at the back doorstep with beer can in hand. My mother says that she once touched her tongue to the can and experienced the bitter, horrible taste of beer, which further established her resolve not to drink alcohol in the future. So that is why we don't drink alcohol, because you are a drunk with a buzz and alcoholic system, not really a rational person with anything intelligent to say.
