If you could teleport anywhere in history

I think i would pick the High Middle Ages in the 12th century and just walk around and observe people to see how similar and how different people lived back than. And also see how different people lived in the high middle ages in different European countries.


I mean if i could transport anywhere in history and i could be invisible and observe. i would visit and observe as much as possible. from 3.7 billion years ago until the day i was born in 1983. I would not pick any point in my life time because that is just boring.
