Unless you’re white it wouldn’t be great going too far back in time.
And we have no idea how dystopian the future might be so you don’t want to get locked up and have to work in some Amazon prison warehouse.

Or Ghost. Where Patrick Swayze is a sexy ghost who gives it to Demi Moore while Whoopie Goldberg watches.
I think, It’s been a while since I’ve seen it.
