There are too many fat people. Australia, the UK and ('duh') the USA are facing an obesity epidemic. The fatties are taking over. Apparently the world is full of them, and we're not careful they shall slow down the planet's rotation. The earth will wobble on its axis like an overweight child jumping on a pogo-stick before unbalancing itself and spinning wildly out of control. The only question is...where are these fat people? I see some of them on the roads, pancaked by trucks which don't weight much more than them. Occasionally a jellified human mass will pass in front of me in the cinema. However, surely we ought to see more of these whale-men/women on the streets, judging by the proportion reported as 'overweight'? Surely they can't all be hiding in their hollowed out armchairs, gulping frothy beer from oversized cans in basements with temperatures optimised for adipocyte growth? Where are they? The streets should be lined with human beings wider than the back of a wide-goods vehicle, broader than the brim of a large buckets of congealed lard waiting to splash over the unwary bystanders unfortunate enough to brush past them. Where are they? Some people are unable to lose weight - leptin deficiency. They happen to number in the dozens (out of approximately 6 billion human beings). Thank goodness for the conservation of mass - I'd just started to wonder where all the burgers went.
By the way: BMI 19-25 is ideal, in case you're wondering about the title.
