well, though I cannot prove the following, it does seem plausible from my study of human history, so factor this in: most people, even today in an age in which mechanized transport is widely available, spend their entire lives within thirty miles of where they were born.
Not me. I average over 4000 miles between where I was born and where I live. (I say average, because I am always traveling LOL!) I once had 3 simultaneous apartments (with three rental cars parked at airport long term parking) in three different cities, one on each coast, I was flying so much.
