We grow our food using all manner of nasty chemicals, then we pasteurise, pressure cook, refine, process, irradiate, de-fat, de-nature, de-caffeinate it and substitute natural fats for altered ones not found in nature and then, when we get a bit crook, the doc tells us the ciggies cause it.
And the really stupid part is, we believe them cos they are the self appointed, self referenced gurus on the subject. Does that sound familiar?
