I did qualify my remarks by saying some as I did not intend to imply all or even most non smokers are holier than thou.
Believe me I have suffered the effects of smoking. Even before I was born I was a passive smoker as my mother smoked throughout her pregnancy and I was consequently a very small baby. I grew up in a smoke filled house and had to put up with various smoke filled workplaces, restaurants, cinemas, theatres, buses, trains and even aeroplanes.
I don't expect I enjoy the smell and health hazards any more than you do.
You are one up on me in the virtue stakes in that I tried a cigarette when I was about 14 and you have never smoked.
