And the rises and falls of civilization story is there were more people who lived in the Roman Empire because it was more advanced. It could support a larger population. And then the population declined. The city of Rome maybe had a million people at its peak. And then by, I don't know, 650 AD, maybe it's down to 10,000 people or less. You have this complete collapse in population.
