Ha, a proof that by watching YouTube videos you learn something.
This was covered by one of my favorite series on YouTube. Here is the particular video: https://www.youtube.com/watch?v=fD-R35DSSZY
I don't think his recent work video was good at all, namely that he falls into the same trap of idolizing days of yore while thinking about the current day realistically, a form of recency bias known as rosy retrospection. In short, serfs' (and other pre-Industrial peoples') "free time" was not free at all, it was spent doing other sorts of manual labor that wasn't their primary work but nevertheless needed to be done, similar to the chores we have today but much more strenuous. I'll add these comments on reddit that serve as much more of a realistic view of work back then [0] [1] [2].
I haven't found any channels quite like his one. That being said I do find toldinstone to be quite good regarding ancient history. Outside Youtube, https://acoup.blog/ is a great history blog.
