In the developed world, average life expectancy is increasing. What problems will this cause for individuals and society? Suggest some measures that could be taken to reduce the impact of ageing populations.
-----------------
People who are living in developed countries tend to have longer average life expectancy. This causes various advantages for individuals and society, and I believe that there are several solutions to mitigate its negative impact.

The rise in average life expectancy in the industrialized nations definitely has numerous adverse influences. Firstly, instead of employing young and energetic staff, companies and corporations have to hire elderly people as main source of human resources. As a result, the level of job performance of such firms in particular and the national productivity in general can be reduced substantially. Secondly, individual and social expenses will increase because of taking care of the ageing population. Younger generations might spend more time, money and efforts looking after elderly people, whose proportion of the national population are growing. Also, governments partially have the responsibility of paying more for insurance premium of retired people.

There are various approaches to reduce these negative consequences. Local societies could allow elderly people to work by creating voluntary unpaid job for them. This not only helps to save local budget on hiring workforce but also makes old people to live more independently and positively. In addition, governments can encourage them to take part in exercise programs. It will prevent them from facing serious health problems which results in increasing health care fee.

In conclusion, rising average expectancy will definitely do harm to individuals and society of developed world, but I think this situation can be handled dramatically in various ways.
