Nanocosmetics Used Since Ancient Egypt
Roland Piquepaille writes "French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide (PbS) nanocrystals with a diameter of only 5 nanometers. At a moment where many people wonder if the use of nanoparticles is safe, it's good to know that nanotechnology has been widely used for a very long time."
...all three civilizations are extinct. In fact, every single civilization with a hair style that drew comments has become extinct! It's not the nanoparticles, it's the alien creatures that infect people's hair and eats their brains out from the scalp down!

You are obviously unaware that "The Internet" is purely an American device, which the USA generously allows other "civilised" countries to use.
As such, it is clear that Wikipedia is way out of line listing uses for products/resources for "uncivilised" regions of the Earth. I suggest everyone start posting on WP to fix these errors - after all, how can you have an "encyclopedia" if it caters to people who arn't the leaders of "Freedom" or "Democracy". I also notice they have references to barbaric religions like "Buddhism", "Islam" and even contains contents that fails to condemn "homosexuality", "Catholicism" and "Evolution".
Please, please, think of the children! Do we really want them to grow up being informed about The Rest of the World?
