Good thinking, crisc! Maybe I was shooting too young...
My 6yo loves How It's Made, Dirty Jobs, and Myth Busters, too. Plus Survivorman and Man Vs. Wild, and anything on the Science Channel, Animal Planet, History Channel or the Military Channel (the latter with Dad only, just to be sure it's not too graphic).
He'd watch TV all day if I let him. Even though anything he watches is at least marginally educational, I prefer no more than an hour or so per day of media time for him. (A bit more on the weekend, but not all day or anything.) So I REALLY have to limit it for him!
He also likes Star Trek in all its incarnations, especially TNG and Voyager, and that's fun to watch as a family.
