I just watched this video on a plane, going nearly 600mph at 33K ft above northern Canada. The pace of technological evolution I have experienced in my lifetime is absolutely miraculous.
And what always amazed me was that she grew up with people (mainly farm workers) who had never been more than 5 miles from where they were born. I go further than that to visit the supermarket!
This isn't as remarkable as it sounds when I say this was in 1960, and the neighbour was 80 something, and his uncle had been born in 1798, and had lived well into his 90s. But is still seems such a large span to be able to reach back.
