When I was in high school they bought a portable B&W video recorder
that was about the size of a carry-on bag, with a shoulder strap. It
cost about the price of a cheap car at the time. As a Film and TV Arts
student, I was allowed to take it home and play with it. The schools
had a ton of money back then. Unlimited 8mm film and processing.
Beatiful fully equipped auto, wood, electrical and machine shops
including EDM machines. You can imagine what kind of mischief a boy
that age could get into with a novel device such as a portable VCR.

Mine's okay. ;-) In moderation, that sort of stuff's not so bad.
McDonalds, potato chips and donuts are probably a lot worse for you.
