So THAT'S How It Works

Researchers have exciting news on why we sleep and how necessary a good night's sleep is to our health.
Like a janitor sweeping the halls after the lights go out, major changes occur in the brain during sleep to flush out waste and ward off disease, researchers said Thursday.

The research in the journal Science offers new answers to explain why people spend a third of their lives asleep and may help in treating dementia and other neurological disorders.

In lab experiments on mice, researchers observed how cellular waste was flushed out via the brain's blood vessels into the body's circulatory system and eventually the liver.

[...]The process is sped along during sleep because the brain's cells shrink by about 60 percent, allowing the fluid to move faster and more freely through the brain.

The whole operation takes place in what researchers call the glymphatic system, which appears to be nearly 10 times more active during sleep than while awake.
So, to sum it all up, my brain needs to take a good healthy dump at night; it pretty much works like my ass.
Somehow I always knew that.

Aye, but there is a LOT of cover to be found there. Should the little woman think you are being stubborn, wrongheaded, or a jerk, just tell her your mind isn't "regular". Most of my women have known, though, and kindly suggest I sleep. Sometimes wishing it was with the fishes, but take advice with a grain of salt?

Of course, this does make me wonder. What if the liver isn't working properly? I can see that actually leading to a form of insomnia, because the brain can't empty, there is no place for it to go. It might even, sort of, back up. This makes some sense to me, in my condition, where organs have brownouts from too weak of a blood flow or something. A low functioning liver might even make sleep nearly useless for it's intended purposes. It can all spiral downward quickly, and each problem cascades. Still, I'm not dead yet, so I'll keep working on it.
