To start with that I can't imagine my life without a computer. Everybody knows that using computers and the internet develops important skills in young people.On the one hand, teens can visit different countries and cities online. They meet new people and communicate with their peers from different countries. Besides, they learn a lot about the life of people from other countries. Of course, young people find a lot of useful information in the Internet. 
On the other hand, technology has created less free time rather than more. Teenagers spend much time chatting and living in virtual world. They have no time for real communication with their peers. 
In addition, I would like to say that leisure activities have become too expensive. Nowadays, only a few parents can let their children have fun in the real world. Tickets to the theater and cinema are  too expensive, and almost every youth disco is high paid.
In conclusion, I believe that children need more play time in order to develop into healthy adults. They should spend much more time in the fresh air. Adolescents should keen on sport:  swimming, athletics and others. Computer games are not useful for their health.
