Adam, if you were an alcoholic, and you haven’t had a single drop of alcohol for, let’s say, 5 years…. should you address that you are an alcoholic? Even if you haven’t drank a single drop of alcohol in such a long time, and you no longer think about alcohol?
Once you haven’t stuttered in a long time, and you no longer fear words…. you simply forget about stuttering. It is no longer is among your dominant thoughts. It has become part of your past, but not your present, nor your future. Why worry about it then?
