I like alcohol when I social. And the odd cigar when I'm intoxicated. Since coming to the Middle East, my alcohol levels have gone down drastically however, and by default smoking as well.
I do both. I guess if I ever am forced to give up one of them for some or other reason (it better be a good one), I'll have to give up the other one as well.
Neither. I'm a bit of a health nut. I don't mind the occasional celebration or party but drinking distracts me and I'm too busy to afford too many distractions.
