Let's say, there is really some kind of magic and you have the opportunity to either get back into your body when you were a kid or you could take over the life of a brain-dead kid and live in this year.
What would you choose?
Do-over sounds great, you could game the system, could get super rich etc. But could you live with knowing the future? All the deaths? all the terror attacks? Who would you try to save? (except family, loved ones and close friends, that is a very good reason to do a do-over, I had one death in my family that I could maybe save, it was a cousin of mine who accidentally strangled himself to death while trying to scare his brothers. But even then, that was some 20 years ago and I don't know the correct date when that happened, I would have to ask beforehand.) And even then, with you changing the timeline, there could be deaths that weren't there the first time.
But Moneymaking is easy, even if you don't know anything about the stock-market, or play it safe with the known companies. You just have to remember to buy some bitcoin in 2010 and you will be a billionaire in 2017.
I am more in tune with "taking over" the life of someone young in this current age, even if it is a shit time at the moment. I want to see the world evolve, I want to know humanity in 50, in 100 years, I want to maybe see the mankind colonizing the stars. Also, I wait for the next book of Game of Thrones for 7 years already ;)
My dream scenario would be that I was myself as a preteen again but all of my family, friends, school buddies and neighbors would also be their appropriate age like they were in the 90's. So, living your youth in 2017 with the bodies of the 90's (and I still have my memories, ha!)
