Living in the country is what people from the city often dream about. However, in reality, It has both advantages and disadvantages.

There are certainly many advantages to live in the country. First of all, you can enjoy peace and quiet. Moreover, people tend to be friendlier. A further advantage is that there is less traffic, so it is safer for young children.

However, there are certain drawbacks to live outside the city. Firstly, because there are

fewer people, you are likely to have few friends. In addition, entertainment is difficult to find, particularly in the evening. Furthermore, there are fewer shops and services which means that it is hard to find work. In conclusion, it can be seen that the country is more suitable for some old people than others. On the whole, it is often the best for those who are retired or who have young children. In contrast, young people want to get careers which are better provided in the city.
