Another theory on Global Warming.

I have another new theory on global warming, its being caused by fat people.
Yes that's right. If you have ever put your hand on the side of a car wheel at the end of a journey you know its hot. That's friction. It's caused by the bearing spinning at several thousand rpm causing them to heat up. A wheel with greater mass heats up more because it takes more energy to turn it and so there is greater friction.
The earth is a spinning globe in space and we are surrounded with atmosphere, the more mass there is the more friction there is and so the hotter things will get.
And so my theory is that as there are more fat people there is more mass and so more friction equals more heat. Therefore we have global warming.

As a theory its total nonsense but I though I would share it with you anyway.
