Here is a free idea for any inventors out there.

A TV remote control that detects when you fall asleep and pauses the video/dvd/tv so that you don't miss anything.

Falling asleep during a narrative can be quite traumatic. You wake up with such a sense of confusion and discontinuity.

It could also be hooked up to the ratings system, to give TV stations a better idea of what is actually getting watched, rather than what is slept through.

I give you this idea for free, and ask only that you send me a few free units once they start being manufactured.
