on topic: me. I stayed up all night working on something I needed to finish like today. Got to bed at 8 am. Set the alarm to noon, cause I still had stuff to do (didn't finish the thing). But APPARENTLY my body was tired or something, because I turned the alarm off at noon and slept for another FOUR hours, essentially killing the "office hours" part of the day, when people with normal jobs are available. I'm so in the flesh about this.
