Someone creates a machine that can (through the power of whatever scientific or magical mumbo-jumbo you want to imagine) put you into the mind of anyone in history to experience anything they experienced. You will see what they saw, feel what they felt, think what they thought, and live what they lived. Then you’ll be back in your own reality.
You’ve only got one. It can last up to 24 hours.
What event, if any, do you choose to experience?
(Let’s ignore the real ethical implications of doing a ridealong in an unwitting brain for right now, please.)
