Sleep - what is it for

Sleeping, from a practical point of view, is a waste of time.

I mean seriously - you're lying still in the dark for, what, seven hours doing absolutely nothing? Not moving, not exercising, not even watching a movie. Sounds very similar to someone slacking off in the canteen during work hours, at least he's getting his daily dose of caffeine.

I guess sleep is natures way of giving you an excuse to not work. "Boss, sorry, I can't work on those 297 reports you sent me because I'm tired and need to sleep". Lame excuse right? Anytime you have too much to do, you invoke sleep - and some people even have the cheek to actually doze off. Talk about lack of pride.

Ok. So humans need energy - and we get it from food, water and sleep. Why can't we substitute less sleep with more food, or water, or chocolate? After years and years of evolution, are you saying our systems are not flexible or advanced enough? I've never seen a cheetah having dark rings around its eyes after a long night of hunting. But then again, cheetahs rarely hang out in the canteen drinking coffee.

It's a real pity. Just when the kids fall asleep and you have some time to yourself, the tiredness bug hits you and then you yourself need to shut those eyes too. Honestly, it doesn't make sense having everyone sleep at the same time - someone should be out there watching a movie or working on those damn reports.

Need to stop, I'm starting to yawn now.
