How about a revolution in convenience sleep?

Sleep - what a beautiful word. Say it. I bet you feel like a sleep now. 

There are few words as suggestive. If you say burger to me, I will want a burger. But then when I have had a burger, I’m ok for burgers for another while, say an hour or so. But if even I woke up from a Rip Van Winkle-esque sleep my first thought - after I wondered where all the robots came from - would be that I wouldn’t mind rolling over again for a bit of a sle-epilogue.

Our attitude to sleep changes over time. As a child, the need for sleep was primarily the enemy of being able to stay up late to watch Cheers, the finale of the original lizard series V and World Cups in time-zone unfriendly places.
