The English language is quite literally the result of efforts by Norman soldiers to pick up Saxon/English barmaids.
All joking aside, I have found my recent brush-ups on world history to be as fascinating as they were when young and truly enjoy hearing and reading as much as possible about long ago and far away. As bad as the good old days were, they sometimes provide an escape from the bad old current days and may shed light on how we got from there to here.
