"How It's Made" ... TV to slumber by...

I love "How It's Made". It's so soothing... it is truly TV to nap by. Don't get me wrong. When I can stay awake, I'm fascinated by how things are made. But the combination of the soothing narration, the light repetitive music, and the predictable motion of the machinery and conveyors puts me right to sleep, every time. Two snoozing, purring cats only compound the drowsy effect.
