Do you ever during summer daydreaming think about the passage of time over the generations?
As a small lad I had two living grandfathers who were both born in the early 1880s. And when I think about my youngest grandchildren who have been born in 2009 and 2010 I realize they could easily (or not so easily) live until 2100. To know and see and talk with people whose lives span 220 years is mind boggling. The grandfathers predated automobiles and electricity (at least on the farms). Who knows what the grandchildren will witness in 50 or 60 years?
There obviously have been many changes. Technology, inventions, American ingenuity, etc. have wrought standard of living improvements over the meager living conditions faced by all but the wealthy in my grandfathers' days. Laws and changing expectations have gone a long way toward reducing xenophobia, prejudice and discrimination, particularly among races. Yet hatred, bad behavior and sin have in no way disappeared.
Aspects of living are much easier and more comfortable. Yet the challenges of life are unchanged. Who knows what the future holds?
