We have heard about the possibility of faster airline flights, using airplanes that fly higher above the atmosphere with much faster speeds. In the 1960's, it was predicted that the American worker would have increased leisure time by the year 2000. Just the opposite has occurred. Improvements in technology have enabled workers to be more productive, as expected. We need to be that much more productive in order to maintain the American standard of living.
Wireless telephones are very common now.
I think that you people in 2051 will find it amusing that we used to be tied to a fixed location with our telephone communication systems. There has been a concern that the high-power transmitter in a wireless cell phone would damage our bodies, since we hold the telephone next to our ear, so close to the head. My family has been fortunate to live in a natural forested setting on 20 acres. I like to get much of my exercise by carrying 50-pound logs from the woods to the house, to be used for firewood. I appreciate living in Washington's Clark County, where the jet stream carries the storms during Winter and Spring, where it is so green, and where the open spaces have given us a much higher quality of life than where we previously had lived near San Diego.
