A tax I can support - Fat-gas tax

"The Economic Impact of Obesity on Automobile Fuel Consumption"

This is James Glassman's idea, though I can't find the original source without paying at High Beam.
Scrivener.net:

...the Fat-Gas Tax is a variable rate gasoline tax determined by Body Mass Index on an individual basis. You pay for your gasoline purchase by debit or credit card and the tax is added automatically.

Imagine a simple, single tax that can help avert global warming, de-fund Arab terrorists, save scarce natural resources, reduce pollution AND remedy the government's approaching funding crisis for Medicare (by heading off the coming diabetes epidemic, etc.) ... save private individuals billions of dollars of medical costs from avoided heart attacks and strokes and blood pressure medication prescriptions ... make the general population lean and good looking ... and improve your sex life too! That's the Fat-Gas Tax.
