Illiterate

70,000 being illiterate in Switzerland! While checking the world factbook I saw that Switzerland have people who cannot read and write. But 70,000 of them? Ok, so it could be a rounding error, but still, it means that at least 35,000+ people are not able to enjoy a book or write a letter. Who are these people? I haven't met anybody ever who do not have these skills. Mind you, coming to think of it, many people have a problem expressing themselves. Mainly men though...
