Some people believe that it is a good idea to continue to work at their old age, if possible. To what extent do you agree or disagree

Some people think it a good idea to stay in their jobs when they grow old. Personally, I strongly disagree with them on this matter. I will elaborate my arguments as follows. The primary reason that the elderly should retire is that they are physically fragile. Their immunity is certain to deteriorate with age, so that they are more vulnerable to illness. For them, the likelihood is extraordinarily high of falling ill under the stress in the workplace. When struck by disease, they also have difficulties in recovering readily, and thus, the conditions can be chronic. Considering the potential risk of healthy problems, it is unwise for them to continue working. Furthermore, even though a few people maintain robust health at their old age, they should withdraw from their occupation too - because it is a painful struggle for them to keep up with the times. In the age of technological innovation, many job sectors have undergone disruptive change, forcing professionals in these fields to learn from scratch and explore the unknown. This is just the serious weak point of the elderly, who tend to be conservative and not open to novelties. They usually stick to existing tools or solutions, reluctant to exercise their creativity. For this reason, the best option for them is to simply bow out of the employment market. To recapitulate, infirmity due to age proves a major hurdle to the career development of older people. The era of technological revolution also poses formidable challenges to them. Therefore, they should withdraw from their occupation at a ripe old age, despite their eagerness to continue their professional pursuit.
