Yeah I know about this. The brain doesn't have a lymphatic system, so uses the blood vessels that feed it as a cleaning system too - but, that affects waking experience - not sleeping experience. If we could do all the maintenance work while awake, why bother sleeping - except for dreams.
She is having fun with it - but she can't use it AT ALL properly :D
If we could do all the maintenance work awake then we would have evolved to not need sleep right.
In the meantime the other thing it's useful for is downtime as I know a lot of perople who would have cortisol levels somewhere in the stratosphere (they're already somewhat through the roof) if they didn't need sleep, not to mention that society would be even more of a nightmare because with not needing to sleep there would be the full expectation that we should be grateful for the ability to work a solid 18hr day for a living and we are worthless and lazy and deserve to be destitute and for bad things to happen to us if we would rather not XD
You don't work an 18 hour day?
No, I only work 11-12 hour days and only because I'm trying to sleep more (or at least lie in bed starting repair work on myself while waiting to fall asleep).
Getting lazy.... :D
