It used to be cool, the image of Dean Martin, Cary Grant... smoking! However in the last several years it's become taboo - at least in the states.
The truth is, we've all either seen it, done it or been given it - the evil "stink-eye". More infamous with the crying baby in a restaurant - now the common smoker catches it all too frequently.
I think there is going to be a backlash, the rebels and 'cool' kids will bring it back in vogue. So the next time you see a smoker, don't give the stink-eye, wink or nod with acceptance like your hip to their game - you're in the 'in' crowd.
oh, by the way I'm not a smoker but I support them. We all want to look cool.
