In some countries the average worker is obliged to retire at the age of 50, while in others people can work until they are 65 or 70. Until what age do you think people should be encouraged to remain in paid employment? Give reasons for your answer.

The situation concerning the retirement age is very different in different parts of the world. Some people at the age of 65 or 70 are still in working process, they are taking care of their families, countries and business companies. The situation with the other people is different. They are fit and have good health but, in accordance with the national law regulations they have to retire much earlier. I will discuss the dilemma concerning with the idea of high-level employees leaving at the age of 50, while it is true that the energy level gets decrease at old age and ideas get less innovative impact in tasks, sometimes the experienced ones even at age of 50 or 60 can tackle the precarious situations which young mind cannot tackle.
I do support the latter opinion that is practiced in most of countries where experienced ones remain in job even at 65 age. We can take example Bill Gates whose energy and brilliant insights are still inspiring many adults. It is now the experience he has accumulated as an older man which keeps him on top. I think combining the vigor and innovation of younger workers with the experience of older workers would seem to be the winning hand in the world of business.
There might be assertion to give opportunities to the younger generation, but if everyone retires at 50, there will be a smaller pool of experience at the company. Besides, when I will be of 50 I do not fancy the idea of being put out to pasture. I think I will still be full of energy and enthusiasm with a desire to work, so I hope my workplace will view me as a treasure house of valuable experience to pass along to the next generation.
