Surely the only way something like that would work would be if you retained memories of the consequence of your choices. If you had no memory of having already made a choice and the consequences thereof, what would stop you from making the same choices you initially did, given that you would be the same person in exactly the same situation with exactly the same memory. So if time was just rewound with no memories, I'm fairly sure I'd make the same decisions again (not withstanding any natural randomness). However, if I got to go back and retain my memories, then yes please, sign me up. Many choices I'd do differently simply because I've now experienced one choice. Plus in those type of films they never seem to remember lottery numbers, or which shares to invest in, or to adopt Bitcoin at an early stage etc. Please Register or Log in to view the hidden image!
