When I was a teenager I got drunk regularly every weekend, I smoked a pack or two a day. I didn't like it but since all my buddies did it I kept doing it. My father was furious and I am sure he would hurt me seriously if he could get his hands on me while my mother cried and begged me to shape up. When I graduated from the trade school (at about 18) I just quit drinking and smoking cold turkey and never started again. I bought a racing street bicycle, lost about 20 pound in a month, got a job with telecom, found new friends etc and became adult. Then I joined army for two years and became a man I suppose. Fast forward 42 years, two wives, 4 children, 3 houses, 1 hobby farm and 5 dogs I still don't drink when riding any motor vehicles no matter how slow they are. Do I drink alcohol? Yes. When I got drunk last time? Long time ago that I don't remember.
So I also vote YES for the young man mentioned in previous posts. He will come around.
