Can age restrictions in the workplace be justified?

The issue of forcing workers to retire when they reach a certain age isa difficult one and there is no easy answer. But I think the answer to this question is "NO".I n some fields, age and accumulated knowledge may be an advantage. Researchers, engineers and professors may very well benefit from their many years of experience. It's very difficult to take over their assignment. Without their distinguished skill, we will be at a loss to achieve a challenging goal. It's too short for us to succeed their experience. Furthermore, the merit system has been installed for the last two decades. I believe the system is not a matter of age. As far as people who are willing to work can bear fruit, they should be allowed to continue their career. we might consider raising the age of compulsory retirement so that people who are still working and able to work are not forced to retire.
