IELTS Writing about aging *plz point out my mistakes and tell me what needs to be improved:-) Due to improvements in technology and increase in personal wealth, people`s life expectancy has extended. Despite the fact that older people can contribute extradinarily to society, the demograghic change may lead to some problems. One aging-relevant problem is that the soaring medical care costs may impose a heavy burden on taxpayers. It is widely known that most medical needs and expenditures appear in twillight years.Governments, therefore, are expected to spend more money on seniors` caring, which leads to the thorny situation where working people are required to pay higher tax and other essential public services funded by governments as well like education may face the financial shortage. The slow working pace would be another problem as the number of senior employees increases. It is normal that the ability to absorb information and tackle working issues declines as people getting older. In addition, the elderly tend to reject newly-developed technologies and would be reluctant to use office software. If they postpone retirement, their attendance at working place may result in poor efficiency and profitability of companies and even the whole society. On the other hand, the experience and wisdom of seniors can be considered valuable social property. They have accumulated a great deal of knowledge and skills, which can be passed on to the younger generation. For example, some senior managers can teach young employees about how to manage a company, and how to provide better client service. So young people are likely to make good use of these precious experence to develop their careers, which will eventually benefit the whole society. In conclusion, the considerable elongation of lifespan has put strain on health care system and imposed negative influence on the labour productivity. While seniors` wisdom does count in some circumstances, the economic consequences of an aging society remain unsolved.
