There will be many homes in Britain that still have the last edition of the Home Guide to Nuclear War, issued by the government as Protect and Survive. Maybe in a telephone drawer somewhere, along with the radiator bleed key and a 1976 warranty card for the doorbell.

And as members of the family die and the bodies must be dealt with, Yell will not be the best source of home service providers.
It's about time we scared the youngsters.
