     Have you ever thought about what determines the way we are when we grow up?Remember the

TV program Seven Up?It started following the lives of a group of children in 1973.We first meet them

as wideeyed sevenyearolds and catch up with them at sevenyear intervals:nervous 14yearolds, serious

21yearolds and then grownups.

     Some of the stories are inspiring, others sad, but what is interesting in almost all the cases is the way

in which the children’s early hopes and dreams are shown in their future lives.For example, at seven, Tony

is a lively child who says he wants to become a sportsman or a taxi driver.When he grows up, he goes on

to do both.How about Niki?She says, “I would like to find out about the moon.” And she goes on to

become a space scientist.As a child, softspoken Bruce says he wants to help “poor children” and ends up

teaching in India.

      But if the lives of all the children had followed this pattern, the program would be far less interesting

than it actually was.It was the children whose childhood did not prepare them for what was to come that

made the program so interesting.Where did their ideas come from about what they wanted to do when

they grew up?Are children influenced by what their parents do, by what they see on television or by

what their teachers say?How great is the effect of a single important event?Many film directors,

including Steven Spielberg, say that an early visit to the cinema was the turning point in their lives.Dr

Margaret McAllister, who has done a lot of research in this area, thinks that the major factors are parents, friends and their wider society.
