who would i be?

If i can choose to be another person, i don't know if i choose a specificly one. I would rather to choose a different time to live, to see how was the life there. For example i would like to be an native living before the arriving of Columbus. That would be greate because i would learn a completely new way to see everything. Maybe all that we are taught in school it's fake, maybe the world was something that we can't imagine right now because we are blind. Thats why i would like to see it with my own eyes. I don't think i like to stay forever there, because i think it would freak me out. But i would like to try to learn as much as possible in 24 hours.
