I am not familiar with the statistics regarding Scotsmen and alcoholism. I have come to the realization that alcoholism does not discriminate. It can affect men, women, young, old, athletes, manual labor workers, investment bankers, actors, managers, entertainers, grandmothers, etc., etc., etc. The list could go on forever.
Only the person drinking can say whether or not alcohol has affected them in a negative way. It doesn't matter how much one drinks or how often. The only thing that matters is if the person who is drinking believes they have a problem. It comes down to self-diagnosis, plain and simple.
If someone feels they need to "cope" with alcohol, that may indicate a problem. Every individual is different.
Thanks for the question.
