Sleep is Over-Rated

It's a three-coffee day. Which makes me wonder why we need to sleep at all. 

It's the 21st Century. By now, you'd think we'd have embedded nanobots, bio-electrically-charged stem cells, and sleep-in-a-can for those days when technology just doesn't cut it. 

I mean, seriously.  Why sleep?  Haven't we outgrown that shit yet?
