Assume that the future can change based on your actions, so any historical information that you bring along with you from the intervening 25 years may quickly drift out of the new realities history.
Edit: also assume that you can be given a healthy 21-year-old body if you want or take your previous self’s place.
Further, identification will be provided for you if you were not born at that time.
How the fuck do you take your self’s place? You’re either a your current age trying to identify as a baby or you’re a baby which doesn’t have the mental capacity to remember having the historical info.
I have some crazy news for you. Not everyone is 21. Believe it or not, but there are people who are older than that (I’m one of them! Boo!)
I misread OP. I was under the impression that you reset as a 21 yo
It’s simple. Say for instance you were 30 years old in 1999. You would just slot into your 30-year-old self and have an opportunity to make new decisions loaded with information about a highly likely future.
However, if you were a baby in 1999, you probably would not want to take your own life over so you would choose the new body option, and lead a completely new life separate from your old one.
But how is there not a 24 year difference and 2 of you? Makes 0 sense
Have you ever seen the TV show quantum leap?
That’s what I’m talking about. Your personality, the wave state of your brain that makes you “you” would take over your former selfs body.
Once again though, if that doesn’t work for you, you could just have a new body.
If going back to 1999 would put you into you infant or toddler’s self, then the appropriate choice would be to get a new body.
Ah so you basically reset your life. No thanks
