Yeah, I was thinking why everyone's choosing to go back to fairly recent times!
I'd go way back to like, ancient civilisations like Greeks, Egyptians, etc. Though I'd rather not have my head chopped off or something stupid. But I find stuff like that pretty interesting! Ooh, or Elizabethan England with like Shakespeare stuff. Ooh or even more recently, Victorian times! I wouldn't fancy the whole women not having many rights thing, or the poverty-stricken life, but if it was only for a short amount of time I would so go back JUST to see what it was like! Probably would be completely surreal.
OR I'd be a Native American Indian (yes, like Pocahontas) for a bit just to see what THAT was like! Could do without the fighting and stuff. But yeah, there's plenty I think would be cool...
