Not only does the earth could not stand this exploitation ,but also individuals are exposed to severe competition with discouraging result that some employees experienced sudden death in their work ,which has not been a news for urbanites who fight for a life in cities.

A mature job market is the one where different levels of candidates could find their matching .Besides, a society where the proportion of the elders is beyond certain limit would be exposed with financial challenges .

How to manage this trend of elderly society has been a practical issue for some developed countries and one solution is by social medical insurance and other insurances .
