I never knew that Florence Nightingale was born in Italy. I found this out quite recently, but on mentioning it to my wife, she seemed surprised that I did not know, it was common knowledge, she said.
I wonder if others have found out something they didn't know, which others thought was common knowledge?
Found out something last night that I didn't know - reading the tv mag in the chinese take away I found out that John in Emmerdale (RIP) is married to that Welsh bird with the annoying voice from Gavin & Stacey.
