To maintain a degree of humility I often go to this site to read about day-to-day life in Cuba. It will open your eyes. In the early 70's I got to "see the world" and what I saw was eye-opening then and today it hasn't changed that much for some nations...some have even slipped backward.
I heard once that scientists believed there could be about 20 planets with "intelligent life." I am beginning to think Earth wasn't one of them.
