Brain drain is also known as “The human capital flight”. It can be simply defined as the mass emigration of technically skilled people from one country to another country. Brain-drain can have many reasons, for example-political instability of a nation, lack of opportunities, health risks, personal conflicts etc. Brain-drain can also be named as “human capital flight” because it resembles the case of capital flight, in which mass migration of financial capital is involved. For the balance of power and for the staggered development of the world, it is very important to stop the phenomena of brain-drain.
This will help a particular country to use all local skilled citizens for development and proliferation. But to hold these skilled workers at their native places, it is also important to provide them enough work opportunities and living facilities. For this purpose, developed nations should help developing countries with necessary money and resources. So that each and every human of this planet can have good standard of living and each and every nation can introduce itself as a developed nation. ****
Brain drain (or human capital flight), is the large-scale emigration of a large group of individuals with technical skills or knowledge. The reasons usually include two aspects which respectively come from countries and individuals. In terms of countries, the reasons may be social environment (in source countries: lack of opportunities, political instability or oppression, economic depression, health risks, etc. ; in host countries: rich opportunities, political stability and freedom, developed economy, better living conditions, etc. ).
In terms of individual reasons, there are family influence (overseas relatives), and personal preference: preference for exploring, ambition for an improved career, etc. Although the term originally referred to technology workers leaving a nation, the meaning has broadened into: “the departure of educated or professional people from one country, economic sector, or field for another, usually for better pay or living conditions”.  Brain drain is usually regarded as an economic cost, since emigrants usually take with them the fraction of value of their training sponsored by the government or other organizations.
It is a parallel of capital flight, which refers to the same movement of financial capital. Brain drain is often associated with de-skilling of emigrants in their country of destination, while their country of emigration experiences the draining of skilled individuals. The term brain drain was coined by the Royal Society to describe the emigration of “scientists and technologists” to North America from post-war Europe.  Another source indicates that this term was first used in the United Kingdom to describe the influx of Indian scientist and engineers.
 The converse phenomenon is “brain gain”, which occurs when there is a large-scale immigration of technically qualified persons. There are also relevant phrases called “brain circulation” and “brain waste”. Brain drain is common among developing nations, such as the former colonies of Africa, the island nations of the Caribbean, and particularly in centralized economies such as former East Germany and the Soviet Union, where marketable skills were not financially rewarded #theme :technologiE

Yet,it’s blatantly conspicuous that the deleterious effects of technology out wrigh its benefits.

•• Advantages and disadvantages of living in the country and in the city. There is a tendency in the modern society to abandon the country and to migrate to the city. More and more people, especially young and well educated, decide to live in large metropolises rather than in small towns or villages. The main factor that influences their decision is unemployment problem which is very acute in the country. The city offers many opportunities to young people. First of all, they can attend there the best universities and use the best learning resources which will allow them to develop their knowledge and skills.
Good educational background increases their chances to find employment in good companies which will offer them lucrative posts. People who are ambitious and want to be successful and pursue their careers find in the city many possibilities to realize their potential and to gain the best professional experience. Besides, large modern metropolises provide their inhabitants with limitless sources of entertainment. Young people can socialize in cafes, pubs, clubs or discos or take part in various cultural events, like for example concerts, art exhibitions or spectacles in the theatre.
Moreover, they can enjoy shopping in large shopping centres or department stores. All these charms and attractions of the city are appealing to young people, however when they start their own families they usually start missing peacefulness and tranquillity of country life. As they become older, people are tired with the hectic and stressful city life and often decide to move outside the city. However, country life, although more quiet and peaceful, has also disadvantages. ***Where shall we live? Some may choose to live in big cities, while other like the natural and quiet surroundings in the countryside.
As far as I am concerned, I would like to live in a big city because living in a big city has more advantages than living in the countryside. To begin with, the city is the symbol of human civilization and there are a many facilities for living, recreation and health care. Therefore, living there is more convenient than living in the countryside. Living in such a big city has a lot of advantages. There is a big offer how to spend free time. There are always plenty of social activities, sports events, concerts and other ways of entertainment.
There are more recreational places in big cities, such as opera houses, movie theatres, clubs, and swimming pools. You will have many kinds of entertainment in big cities, and meet many people. In countryside, however, the life may be dull and quite, and you may only have a few neighbors. In a big city, people can take the chances to study and work best. There are many good University choosing in a big city. There you can express your ability to study what you like. Moreover, when you graduate, you also find it easier to find chances to get a good job with good salary, that is quite difficult in small citiesor countrysides. On the other hand, there are some disadvantages of living in a big city. Cities are very crowded. Everywhere there are crowds: on the pavements and in the buses. What is more, the traffic is heavy and city’s car parks are always very full. Sometimes it is very difficult to get from a given place to another. It may take hours! And it follows to that, that the air in the city is more polluted, than in the countryside. People in the city are like ants. They are always in hurry, busy and out of time.
