All humans think alike if you categorize things broadly enough.

All men think about sex, sure. As they also think about people. All men think about things that happen. All men think about life. Astounding observation.

But what are they thinking about specifically regarding these things; the empire as a whole? The military siege on Carthage? The Latin etymology of certain words? The roman numerals in a puzzle game? The idiom 'Rome wasn't built in a day'?

If you can actually think, it's surprisingly difficult not to think about it in some capacity.
