know your facts!

I read this book called "Genral Irnorance" by John Lyoyd and John Mitchinson. I read things like: a chicken can live without its head for two years. Or did you know Penton Randolph was the first president of U.S.? after death your finger nails and hair grows three days later. And many more things that people do not know. It shows that what we know is not alot. Maybe its because people don't bother to get the whole story, or they misunderstand. Ether way, they are ignorant. Not getting your facts straight is costly. Even the simplest things, you should know what your talking about. In history we see many of people make ignorant mistakes, leading others to misguidance. Prosperity and good things come from knowledge... if we truly know it.
