Sleep Tight!

It looks like an old switchboard, but I didn't get any unusual calls.

All those wires are hooked up to sensors that measure twitching and breathing and eye movements and countless other things that one does or does not do while sleeping. I'm sparing you the addition of the air tube and the face mask, at which point the patient looks and sounds like Darth Vader. The point is to get a good night's sleep. The follow-up questionnaire asks if you would recommend this facility to friends and family. Yes or no?
