Research is funny...

I found this interesting, even though anyone who's gone to college could tell you this:

Study: Sleepy Brain Prone to Sudden Shutdowns

Another term that I've heard used for this is "microsleep." Basically, your body is so tired that your brain makes you sleep for milliseconds at a time when you're in the middle of trying to function normally. Ever been working on something and suddenly jerked your head up as though you were just waking up? That's your body telling you that if you don't sleep soon, it will make you, like it or not, no matter where you are or what you're doing.
