If you were given the chance to have your mind, memories and knowledge be put into the mind of a younger self, how far could you go back without the chance of your brain being undeveloped to the point of wiping your memories?
I was watching Loki series and in the show Loki gains the ability to go back in time by placing his consciousness at a young point in his personal timeline. This made me wonder how far someone could go back with safely. Obviously someone couldn’t go back to the point of being a infant because the undeveloped brain would basically auto-wipe anything. Baby brains isn’t exactly a load bearing structure.
