Ana muses on history.
Not mine, though. That I'll save for the psychiatrist's couch.
I'm thinking history in stories.
Timetravel stories must also abide by what we know of history if the character goes back in time. A travel into the future story is more unencumbered, but veers quickly into paranormal genre.
But in a sense, every character lives in a history. The history of their town or city. Setting involves history. Does he live in a modern section of town, but was born in a crumbling slum. Does her father owe gambling debts that she is forced to pay off to protect her younger brother? Her father's history comes into play.
I guess I am using the word 'history' in a liberal sense. But it's more than backstory. It's the vibrant setting we strive to create, and the dynamic interpersonal worlds our characters inhabit.
Every day, yesterday is history.
