As a historian, I love to point out to people how in many instances the good old days were not so good after all. Not that they appreciate my educational efforts, but that’s a different story. A case in point from the recent past, and admittedly not a dramatic one, are play grounds. When I was a kid, play grounds were equipped with a swing, a slide, and maybe a sandbox. Now look at this cool thing! Oh, to be a child again!
