Hey VAR, I was having this discussion the other day. Even in 85 when I joined they encouraged it.
I remember at recruit training (boot camp), the only thing civilian in your room you were allowed to have was an ashtray and that had to be spotless and hidden.
When I joined I did not smoke. My instructor used to come by every night and ask for a cigarette. When I told him I did not smoke, he shook his head and went across the hallway and chatted to the other blokes while he had a smoke.
Being young and dumb I took up smoking. A week later he asked for a smoke and when I gave him one he said 'Good Man'.
The things we do.
I am only 45 and had a lung capacity test just yesterday and only achieved 91 %. Now I am on some more shit to hopefully improve this.
