It has been said that the surest things in life are death and taxes.
Nothing is as permanent nor constant as change.
Everyone is affected by change. This century has experienced more and faster-acting changes than the world has ever known. The baby boom generation has never been without cars, airplanes, radio, television nor Coca Cola. When I was a child, I made recordings by shouting into the big end of a Victrola horn. My first clinical speech recordings were done by bruising an aluminum disk with a diamond point needle.
