Kevin, thanks for reminding me ... anyone old enough to remeber when they used to have signs on buses saying "no spitting"? Hard to imagine a time when people didn't think that it was disgusting and horrible to (skip to the next sentence if you're sensitive!) spit phlegm on the floor of a crowded bus. But it was so once, and eventually folks were disuaded from this dirty habit and TB declined. In ten years time, we'll wonder how we could have put up with public smoking, even if we're (private) smokers. Meanwhile, say not the struggle naught availeth.
