A recent survey shows that children in Britain aren't as fit as their parents and grandparents.
the problem starts a school. Teachers nowadays have to give a lot of time to subject like Maths, English, Geography, Chemistry and so pupils do less pe and Games, Also, most pupils don't walk or cycle to school. Some go on the bus, but more and more parents take their children to school and back by car.
When they get home, they sit down and watch TV or play computer games in their bedroom.
This problem about young people isn't just a British problem. Surveys in other countries show that it's happening all over the world. Children eat too much junk food, the don't read books, and they don't take enough exercises, because they've got all these wonderful things - televisions, video - recorders, DVD-s, computers
