Not long ago, all the knowledge of a person receives from the books. Books to read at any age. What now? Books to read less and less, especially the younger generation. Why? And because no reason. All the knowledge you can now search for a variety of electronic encyclopedias and on the Internet. This is faster and more convenient. While you read a book, and will choose the right information on the Internet, you can view multiple sites and get more information. But is it good? Not really, I guess. People stop to read the scientific books, the classics this leads to a decrease in the level of knowledge. It remains more free time and can play on the same computer, chat, t. E. Spoil the final vision and posture. Instead of walking and sports.
