First of all, this makes my mind hurt a little...!

But then come thoughts of destiny, am I/was I destined to be who I am?

Or the old science fiction time travel premise of being the "same person" but in a different time and place.

I also think about these things when I vacation. I ponder what it would be like if I had grown up in this place. Granted, I am typically in a pleasant location. I rarely have these thoughts when in the "bad part of town" :)
