It's funny how sometimes vanity can keep us going!
I remember when I quit smoking it was because I was listening to an old lady talk, who had clearly smoked her whole life, and thinking to myself,"OMG, I *never*want my voice to sound like that!" The thought of my lungs turning black wasn't really causing me much concern but having wrinkles around my lips and getting a deep, raspy voice....well, that did it! LOL
