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.
So, going back or forward in time like Ebenezer Scrooge in A Christmas Carol would probably be ideal.
Yeah and scaring the shit out of grandpa doesn’t alter the timeline, as you know.
