Fans, fees and followers: How celebrities from four different walks of life stack up against one another in speaking fees and much more. 

• See that gerbil peering at you? That's not just a cute animal, that's a member of MI5. Gerbils were trained to fight terrorists in the 1970s. Seriously. And that's only one of 10 wonderful examples of how animals have served in the military.

Many women have wondered how they fit into the green jobs revolution. The answer, according to our business blogger, is white-collar jobs.
