Early Riser or Night Owl? It makes a difference
This new study shows that how we sleep often reflects how we function intellectually and socially. Researchers claim that early risers tend to “reach conclusions through logic and analysis. Night owls are more imaginative and open to unconventional ideas, preferring the unknown and favoring intuitive leaps on their way to reaching conclusions.
Morning people are more likely to be self-controlled and exhibit “upstanding” conduct; they respect authority, are more formal, and take greater pains to make a good impression. (Earlier research also suggests that they are less likely to hold radical political opinions.) Evening people, by contrast, are “independent” and “nonconforming,” and more reluctant to listen to authority—which suggests that teachers may have several reasons to prefer those students who wake up in time for class.

My husband and I do not match this study AT ALL. Either we are the exception or he didn’t study enough! :)
I wonder if you could simply chalk it up to young and idealistic vs old(er) and conforming.
having crested 30, I can say I’m as guilty of being a night owl today as I was 15 years ago. and they’re not too far off.
