What industries and things will disappear when our generation dies off? This occurred to me when we were in a store recently buying greeting cards. None of our children or grandchildren send greeting cards anymore. It is kind of like writing a letter with paper and a stamp...young people just don't seem to do it. The U.S. Postal Service struggles as no one uses first class mail much, which used to be their exclusive bread and butter. Perhaps both the Postal Service and the Greeting Card industry will go away.
