For example, Joe Biden was literally born when the battle of Stalingrad of World War 2 was occurring. Biden's literally old enough to have lived in the same era as the generation that lived during the American Civil War were dying out.

Anyone that was born in the 70s, for a brief time, lived on the same earth at the same time as the last living emancipated American slaves still drew their breath.

"Ancient history" is closer to us who are alive than we can truly perceive and comprehend. The past's heavy hands rest on our shoulders, burdening the present with the acts performed hitherto each passing minute.

A quote:

'Men make their own history, but they do not make it as they please; they do not make it under self-selected circumstances, but under circumstances existing already, given and transmitted from the past. The tradition of all dead generations weighs like a nightmare on the brains of the living.'
