For many its the Roman empire or the Greeks. Similarly ancient Egypt. Or the British empire. Maybe the Japanese, Chinese and Norse as the next 3.
I have deliberately not mentioned time periods there.
These are the most commonly beloved. What are your favourites and why?
How does that matter here? Not obsessing over the past doesn’t mean that you don’t know and don’t study it.
No, “not obsessing” doesn’t mean that, true. But “here and now is the only thing that matters” kinda strongly implies it.
Not really sure if obsessing is the right word from OP but maybe more most interested in?
