Children of the 21st century are more advanced than previous generations because there are a lot of different techniques in their possession. Today, almost every child has a phone, a computer and knows well how to use them. But for the health and proper development of the child games in the open air are very important, and not constant sitting indoors. Children still love to frolic on the playground, digging in the sandbox and ride on the roller coaster.
