Makes you despair for the future of this country!!
Why? The world doesn't work as it did 50 years ago - children who don't know where fish-fingers come from can probably find their way around computers and digital TV recorders almost as well as their parents.
By the time they need the knowledge about cheese and carrots these children will have acquired it. The future of the country doesn't depend on people knowing those things when they're in the first decade of their lives.
