Experimental Archeology was something I discovered a couple of years ago thanks to Youtube. The first ones I found were Secrets of the Castle hosted by Timeline - World History Documentaries, and Victorian Farms hosted by Fred Fernackerpan. Suffice to say, I binged for days on these and the other series by these hosts. They were full of new information and wonderful details about the day to day life of people from those eras. And those details are absolutely vital for my building believable settings.
Since then I have come across more and more examples of this mindset, all focused on different time periods and topics. Fair warning, a large number of my future blog posts will involve me geeking out about some of my favorites.
