The New Kid on the Block, Rem Sleep

Human beings seem to be the only species that deliberately deprive themselves of sleep for no apparent reason. Mother nature has never had to face the challenge of a lack of sleep, because no other species does it. We imploed so quickly when we don't get enough sleep, because there is no safety mechanism. And then you the new kid on the block, rem sleep, if you get the chance, because they sleep appropriately, then you get your rem sleep. But i do want to come back to this point about humans being a deliberate sleep depriving species.
