The life in this country 50 years ago.
On the one hand a 50 year period for the country is not very long but on the other hand great changes have been rapidly taking place in this country since the 70s. What are these changes? First of all I'd like to mention the development of new technologies in modern society, for example wireless connection, appearance of the mobile phones. For people from that time it was fantastic but for all of us its quite an ordinary thing today. Then we can't stand mentioning  the Internet that is a necessary thing almost everywhere nowadays and it's difficult to imagine how people lived, worked and studied without computers at that time.To my mind the life in this country now became more complicated than it was 50 years ago, but more challenging and interesting.
