The Daily Mail reports that 'yob culture is being fuelled by a failure to promote sport in schools'.
Researchers from Oxford University have concluded that the Government's aim of pupils taking part in at least two hours of physical education each week was inadequate. Competitive sports are particularly important for boys, who regularly under-achieve academically compared to girls, they said. Excelling on the playing field can boost the status of less academic boys and motivates tem in class.
I have definitely found this. You pick a boy for the school football team and his work in class suddenly improves dramatically!
