I have some that are time related:
The pyramids were as old to Cleopatra, as Cleopatra is to us.
There are still children of US Civil War soldiers alive today. There were widows of Civil War vets alive until 2003!
The grandchildren of US President John Tyler (in office 1841) are still alive!
One of my colleagues was born in the USSR and has loads of stories about how shit it was. It feels like it was ages ago but it was his literal childhood.
Someone born at the very end of the 1800s would have been a teenager in WW1, reaching middle age in WW2, been retiring in the swinging sixties, then watching the digital revolution in their old age. Amazing!
