26-hour syndrome

Let me explain. There are days when I want to go to bed at 12 midnight, and I get up at 7 in the morning. The next day, I would still want to hit bed at 12, but I'd get up at 9am. The next night I just keep tossing and turning for a couple of hours if I hit bed at 12. I feel if the day was a couple of hours longer, or if I could happily live a longer cycle - sleep more, wake more - things would work out much better. Isn't it possible that God made random errors in manufacturing human beings, and while many were aligned to the 24-hour cycle, some were not?
