Well, I also chew sugarless gum a lot, and brush my teeth 3 times a day. So hopefully that minimizes it. I dunno, there was always the massive amounts of coffee, so...they're already under attack. It would suck to get extra years, but with awful teeth.
I am interested in what anyone who's used e-cigs thinks.(I also dimly remember an Al Jaffee invention remarkably like them, but don't have that MAD anymore...)
