...Now, when you think about penguins,first take a deep calming breath, and then think "cuddly". Take another breath,and think "cute". Go back to "cuddly" for a while (and go on breathing), then think "contented". So when you think "penguin", you should be imagining a slighly overweight penguin(*), sitting down after having gorged itself,and having just burped. It's sitting there with a beatific smile -the world is a good place to be when you have just eaten a few gallons of raw fish and you can feel another "burp" coming.
