Aging Queen

There lives a man in Bradford who ages as the Queen does on coins
For long periods his face remains the same
But once every few years he suddenly becomes remarkably older
When this happens
People have heart attacks
If he has kept the same face for fifteen years people become warey and attempt to prepare themselves for the transformation that is forecast
His wife employs police sketchers to try and give her an artists impression of what to expect and refuses to use her finest china.
