Tired now, really left this post too late to write. Just saw the excellent science fiction film, 'Looper'. Basic outline: -
In 2072, when the mob wants to get rid of someone, the target is sent 30
years into the past, where a hired gun awaits. Someone like Joe, who
one day learns the mob wants to 'close the loop' by transporting back
Joe's future self.
So it made me think would I want to meet my future or past self ? Me, I would rather see my past self and give myself a few tips of what to do and what not to do. As my husband said, he wouldn't want to, because if one changed something in the past it could effect your future.
However if I just wanted to travel back time, I would choose medieval or Victorian London to travel back to. Would you want to meet your past or future self or just travel to a different time period?
