I don't drink alcohol. In my younger days I was a smoker. Because of that, my medical records show me as a smoker, as it does for anyone who admits to ever having smoked, even if they haven't had a cig for 50 years. If you have ever smoked, you're classed as smoker.
I don't have any health/medical problems because I won't be ill. It's not allowed. It never crosses my mind that I have any problems, healthwise. Because it aint allowed, see?
