Blame your parents?
Alcoholism is a disease. If I had a gene for it I hope I wouldn't indulge.
My father died of heart disease. I remember him eating salami and eggs after midnight, eating foods with processed oils, having desert every day. I don't recall him exercising. I'm almost as old as he was when he suffered his 3rd heart attack and I am 80 pounds lighter than he was.
I too may succumb to heart disease but will not blame that for my lifestyle choices.
