One of the few New Year's resolutions I was able to keep. I quit 8 years back after some 40 years of smoking.
I do not understand the hype of this making people sick crap though. It doesn't bother me one iota to be in a room where others smoke. Never did even when I was cold turkying it. I just made up my mind that it was time to quit and did so. To me it isn't that much different then to be next to a campfire or a fireplace with a fire going.
