From CBS, ABC, CNN and the New York Post to the British tabloids, everybody delivered the sad news: Blondes are dying out. It was attributed to a WHO study but the organisation had done no such study. It was such a good story that nobody had bothered to check, while picking it up from somebody else. WHO traced the story to a German wire service, which in turn was based on a two-year-old article in the German women¿s magazine Allegra, which cited a WHO anthropologist. But there was no record of such a man working for the WHO. CNN said later it regretted the error.
