Nowadays, generations are wildly different from previous generations. And it seems to be accelerating. There's like 3 discernible generations between zoomers nows, and boomers are pretty much all the same.Before the modern era, basically right before the Italian Renassiance. There was no difference amongst generations. If you were 20, you wore the same clothes as your great grandfather, or even older centuries of ancestors ago. Language changed gradually over centuries, and there wasn't generational slang. For the longest time, language was the only major change over the centuries. Rituals and customs took centuries to change, but changed relatively fast. Everything else changed very little.If you were a peasant in England around the year 1300, you wouldn't be much different from a peasant in the same region in the year 300, a thousand years earlier. The only difference would be language, and a few other things.
