      I was interested to read a newspaper article about a new concept in old people's homes

in France. The idea is simple,but revolutionary-combining a residential home for the elderly

with a nursery school in the same building. The children and the residents eat lunch together

and share activities. In the afternoons,the residents enjoy reading or telling stories to the

children,and if a child is feeling sad or tired,there is always a kind lap to sit on and a cuddle.

There are trips out and birthday parties,too.

      The advantages are enormous for everyone concerned. The children are happy because

they get a lot more individual attention,and respond well because someone has time for

them. They see illness and death and learn to accept them. The residents are happy because

they feel useful and needed. They are more active and more interested in life when the

children are around and they take more interest in their appearance,too.

     Nowadays there is less and less contact between the old and the young. There are many

reasons for this,including the breakdown of the extended family,working parents with no

time to care for ageing relations,families that have moved away,and smaller flats with no

room for grandparents. But the result is the same-increasing numbers of children without

grandparents and old people who have no contact with children. And more old people

who are lonely and feel useless,along with more and more families with young children

who desperately need more support. It's a major problem in many societies.

     That's why intergenerational_programmes,designed to bring the old and the young

together,are growing in popularity all over the world. There are examples of successful

attempts all over the world. Using young people to teach IT skills to older people is one

obvious example. Using old people as volunteer assistants in schools is another,perhaps

reading with children who need extra attention.
