Far out in the uncharted backwaters of the unfashionable end of the 
Western Spiral arm of the Galaxy lies a small unregarded yellow sun. 
Orbitting this at a distance of roughly ninety-eight million miles is an 
utterly insignificant little blue-green planet whose ape-descended life forms 
are so amazingly primitive that they still think that digital watches are a pretty neat 
idea.
This planet has, or rather had, a problem, which was this: most of the people living 
on it were unhappy for pretty much of the time. Many solutions were suggested for this 
problem, but most were largely concerned with the movements of small green pieces of paper, 
which is odd because on the whole it wasn't the the small pieces of green paper that 
were unhappy.
