I am 62 next birthday. In my lifetime I have seen smoking go from being thought glamorous to now being seen as stupid.
When I first started smoking at the age of about 14-15, nearly everybody I knew smoked...parents, Parish Priests, Teachers, Doctors, and sportsmen.
A slightly older contemporary at my Comp. in Swansea was Merve the Swerve ( Mervyn Davies for the non-cognoscenti ! ) His photo was everywhere along the corridors at school, and he was a big hero, him being probably the greatest No. 8 that Wales ever produced. But he was a life-long smoker and died of lung cancer in 2012. I quit smoking in my mid-20's...if I hadn't I wouldn't be here now, of that I have no doubt whatsoever.
Until recently, every Pub and cafe in Wales stunk of smoke and all the tables had overflowing ashtrays on them. Just going to the Pub for an hour meant that you had clothes reeking of cigarette smoke for the rest of the day.
That situation has now changed out of all recognition and legislation has played its part in the change. I welcome this new move and would hope to see it reproduced in other parts of the UK as well.
