10/9: enough sleep!

It's hard for me to gauge the effects of being sleep-deprived when I'm actually sleep-deprived. I mean, I can tell that I'm tired and groggy and slow--but I can best register the consequences of sleep deprivation by contrast, when I'm not directly experiencing them. Last night I must have gotten enough good sleep, so today I was able to read with a clear mind and finish all sorts of tasks in a timely and sane way. (And I didn't need to resort to caffeine.)
