world become old

  Last week I saw a news from a website said that people will retire till 65 years old in China and Americans will be retire at 70. And the reason of make people retire more and more late is that the government can not pay the social insurance's money for the increasing population, some experts even said people shouldn't have 30 years social insurance.They said as people improve the medical technology, people can live longer so they should work longer of course.
  Then I came up with a absurd idea: I graduate from the university when I'm about 25, My father is still working in a company will a group of old men as the same age with him as well as other people.There children will drive them to work, then come back home and do the housework, look at the stock and have some tea as well, cook in the afternoon and go pick up their parents. It's a terrible idea. Is that necessary for the old to work until 65? As we know that the graduated students were hard to find a job for them, if the old people still working, it will be more harder for young people to have a job.
  Old people had already worked for half of their lives, young people is just on time for them to work. Give the old some places and let the young people show themselves. That should be the right role for people.
