     Until late in the 20th century, most Americans spent time with people of generations. Now mid-aged

Americans may not keep in touch with old people until they are old themselves. That's because we group

people by age. We put our three-year-olds together in day-care center, our 13-year-olds in school and sports

activities, and our 80-year-olds in senior-citizen homes. Why?

      We live away from the old for many reasons: young people sometimes avoid the old to get rid of fears

for aging and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it's

so hard that we stay away from the people who need us most.

      Fortunately, some of us have found our way to the old. And we have discovered that they often save the

young. 

      A reporter moved her family onto a block filled with old people. At first her children were disappointed.

But the reporter baked banana bread for the neighbors and had her children deliver it and visit them. Soon the

children had many new friends, with whom they shared food, stories and projects. "My children have never

been less lonely," the reporter said. The young, in turn, save the old. Once I was in a rest home when a visitor

showed up with a baby. She was immediately surrounded. People who hadn't gotten out of bed in a week

suddenly were ringing for a wheelchair. Even those who had seemed asleep wake up to watch the child.

Babies have an astonishing power to comfort and cure. 

      Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my

husband put it, "my grandparents gave me a deep sense that things would turn out right in the end."

      Grandchildren speak of attention they don't get from worried parents. "My parents were always telling

me to hurry up, and my grandparents told me to slow down," one friend said. A teacher told me she can tell

which pupils have relationships with grandparents: they are quieter, calmer, more trusting.
