________________. Fifty years ago, only 4 out of every 100 people in the United States were 65 or
older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect
American society in many ways: education, medicine, and business. Quietly, the growing of America has
made it a very different society, in which people have a quite different idea of what kind of behavior is
suitable at various ages.
A person's age no longer tells you anything about his or her social position, marriage or health. There's
no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The_social_clock that kept us on time and told us when to go to school, get a job, or stop working isn't
as strong as it used to be. It doesn't surprise us to hear of a 29yearold university president or a 35yearold grandmother, or a 70yearold man who has become a father for the first time. Public ideas are changing.
Many people say, "I am much younger than my mother or my father was at my age." No one says, "
Act your age" any more. We've stopped looking with surprise at older people who act in youthful ways.
