I'd be down to do it all over again if i could keep the knowledge i currently have on the world. While it's not everything it's a hell of a good start. But at the same time it's a very scary thought since once you change one thing the rest goes which could just start a viscious cycle of problems possibly making things worse then you ever could of imagined...lol
Besides, it would probably be hella frustrating being trapped in a babies body not being able to do shit with all that knowledge lol.
