I'd love to make it illegal to lie, prevaricate, obfuscate, exaggerate or mislead in any way.
Can you imagine how our politicians and public bodies would cope with that? And advertisers and manufacturers would have to do a major rethink with hype and fancy terms being banned.
For instance, does the average female shopper actually know why 'Ginkgo Biloba' is a good thing in cosmetics and shampoos? Of course not, it's misleading hype.
And when it comes to cars and fuels, well there's a whole quagmire of advertising tripe!
You could spend a lifetime digging out all the dishonesty.
I can't see a real downside to the truth though :).
