When I talk to my students now they can't believe that there used to be smoking on buses, on planes, in the cinema, in restaurants.....
I think I probably wouldn't have started if I was young now, as most of my early cigarettes were smoked in the pub. If I'd had had to go and stand outside I suspect I would not have bothered.
Maryz it was the same in an office I worked in. I used to go and have smoke breaks with the smokers even when I'd given up, I couldn't see how it was fair otherwise.
