Years ago 40/50's smoking was the norm, my father smoked cigarettes then a pipe for years, some of my young friends had both parents that smoked. My parents died aged 81 and 92. Their children are still here and still Ok and I used to smoke too. Years ago the smoking took place in the home and the workplace before the nanny state started telling people of the doom we all faced if we smoked, drank, ate fatty foods and sugary foods etc. So it isn't quite so bleeding obvious to me. Air pollution is much more of a problem now, there is much more air traffic and road traffic. Smokers are now educated to not smoke in front of their children and smoke in designated areas, it wasn't even considered to be a selfish act 70 years ago. Where is the evidence that it was bad for us then?
