Just been reading about Richard Briers actor from 'The Good Life' battling with a chronic lung disease emphysema after smoking '500,000 cigarettes'. I'm pretty sure that the actress who played Vera Duckworth in corrie is battling with emphysema as well due to be a heavy smoker.
Going back in time there were not the warnings that there is now about smoking. Though my own late father if he hadn't have smoked so heavily and my mother in law who never even saw her grandchildren. They would have had many years to enjoy them if only they had not smoked or packed them in a damn sight sooner than they did because by that time the damage was done for both of them.
I watched the TV movie Best of Men (About Stoke Mandeville Hospital during WWII and the start of the Paralympics) the other week and when the injured soldiers were in hospital the German doctor came in with all his new ways and ideas.
Yet they were all still smoking on the wards and even the doc was handing out ciggies
