You have woken up in someone else’s body, someone currently living or dead, real or fictional… and you have to live ONE day in their shoes. You know what they know… but have your soul and your conscience…. and your knowledge. But you can only change one thing and tell them one thing about the future.
Who are you, what day is it? And what do you do?
But what will the consequences be? Think carefully
I would be John F Kennedy, on November 21st 1963.
