My eight year old son and I were talking last night. He said that he wished you could go back in time and live out a period of your life again. So you could go back and live your birthday over again. But you would have to pay.
So you could pay via a travel agent type person to go back, and the price would go up by day. Only the mega rich could afford to live out their twenties from start to finish again for example.
I said 'but what would happen to the them in the present day?' and he said they wouldn't be active there, they would be asleep. I said that I thought that their relatives would miss them, they would miss Grandma if she was constantly asleep due to being back in 1964 again.
Then we wondered whether people actually would do this? Would they go back? Would they choose to go back to a certain day, week etc? How much would you be prepared to pay
