Wer aufhört zu lernen, hört auf zu leben

I agree that smokers seem to take it personally when someone's anti-smoking. I'm not against the person's choice to smoke as such, simply the fact that it affects other people just as much when they smoke. They've outlawed smoking inside buildings here too, and it's amazing. :D Bad thing is that you get hit by it as you leave and enter, but better than smoking indoors.
