Russell Foster is a circadian neuroscientist: He studies the sleep cycles of the brain. And he asks: What do we know about sleep? Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages — and hints at some bold new uses of sleep as a predictor of mental health.

Indeed, while sleep is not God, it is truly a gift from God for our well-being.

Why do we sleep? To allow our bodies to repair damage without having to endure our continuing to inflict even more damage during that repair process. As for “Why do we DREAM?” It’s probably to re-reverse all the already cause and effect reversed liberal fantasy bullshit we’re force-fed every day!

I know liberal BS immediately puts me to sleep.
