My sleep schedule seems to have normalized somewhat: for the last 14 nights or so, I've gone to bed between 9 and 10 and gotten up between 6 and 7. Eight to nine hours of sleep every night, and I'm tired every day. Ahhh, the wonders of a good sleep schedule. Speaking of that, I heard today from a brain expert (via the TV) that in 1900, the average american got nine hours of sleep per night. Today, the average is less than seven hours. Later, the expert said that brain function is significantly impaired when a person gets less than seven hours of sleep. Oddly, our expert didn't make the connection and realize that the average american HAS SIGNIFICANTLY IMPAIRED BRAIN FUNCTION. That explains a lot.
