Beware of documentaries...

I have found that I am highly susceptible to documentaries. I can't seem to stop watching one once I start. As a case and point yesterday I decided to watch some tv while eating my lunch. I really meant to just watch it for a few minuetes while eating, but got sucked in. I ended up learning more than I ever expected about the storm water and sewaged systems in the US. Apparentely our infirstructure is really old and lots of people are having problems maintaining the sewage systems so that they don't contanimate our ground water supply. It was facinating, but this always happens to me. At least I learn something!
