Dogman the subject is emotive and your presentation of it is down right apalling.
As the widow of a man who paid the ultimate price for his failings i know from many months of posting on these boards, that the one thing you should do before writing,is to consider the affects your callous remarks may have on others who are not as saintly as you.
The subject is a great discussion point but not a chance for a reformed smoker to get on his soap box and condemn others who may be trying but havent succeeded.

You might just as well ask why a woman who's husband beats her black and blue stays with him rather than runs for the hills.Human failings are not something the layman should criticise leave that to the experts who at least have some degree of sensitivity.
