During the Falklands war British pilots reported that penguins toppled over backward while gazing at the planes. British navy pilots were then banned from flying low over penguin colonies. It led to a UK government study of the "penguin-toppling effect". For just over 2 weeks a couple of helicopters were flown from varying directions and heights over the penguins.

The result? It's official: penguins DO NOT topple over backwards while gazing at aeroplanes. Phew, glad we cleared that up. They just fall sideways for no apparent reason. (and wassup with the "This video may contain content that is inappropriate for some users, as flagged by YouTube's user community" warning?!) Or sometimes...

Now onto more important things - Your mouth produces 1 litre (1.8 pints) of saliva a day.

A person remains conscious for eight seconds after being decapitated. Well... that's just horrible, isn't it?

One day - learning all of this will make be master of Trivial Pursuit.
