It is clear that there are a lot of opinions about the appropriate retirement age and many countries have different standards about it. However, I firmly believe that 60 is the most appropriate age.
Prior to saying giving (지금은 연설을 하는 과정이 아닙니다.) my opinion, some people claim that the retirement age should be prolonged to by 70. This is because the Because a life expectancy has been is extended and they have to work longer in order to make ends meet to earn the money. Furthermore, there are lots of advantages that come from working when we work with old people. For instance, we people can easily solve some problems easily by receiving advice from them. They experienced various kinds of problems and already know how to solve it and prevent it. We can learn the know-how from them.
Meanwhile, they may reduce the opportunities for young people to get the job since they hold job consistently and companies are not able to hire more employees. Moreover, the salary they receive of them is much higher than one that of a newcomer. In my country, some study said that making old people who have worked for a long time and receive a high wage work less helps a company to hire newcomers. And it can solve the unemployment crisis.

The life expectancy has been extended, but it doesn’t (줄임말을 사용해서는 안 됩니다.) mean that people have to work longer. If we resign from a company early, we (여기는 일인칭이 사용되지 않도록 수정해주세요.) can try to another area which we have not experienced. For example, the friend of my father's retired when he was 55 and it was a much earlier age than others. Most friends of his concerned that he lost his job. Nevertheless, he has enjoyed his new hobby, which is researching cuisines and recording them in his cookbook.
For these reasons, I think it is appropriate for people to retire when they are 60. In my opinion, it is the proper time for them to finish their duty to take care of their children. And it is enough for them to try something new.
