Though I suspect I'm not as strict as the parent comment this is why I avoid alcohol. Father's side extremely alcoholic including several deaths (both liver failure/pancreatic, and alcohol related deaths).

I've never had more than 1 drink in a day and usually only drink once per month out to eat when someone else is driving.

Alcoholism is scary for most of us that have seen it up close.

Both my mother and father have always been pretty dry. My father has maybe 2-3 beers a month, and my mother one mixed drink every 2 months. I've not had any bad experiences at a close personal level with alcoholism.
