We also have more time to spend with family and friends, and enjoy doing our favorite things. Furthermore, we devote more time to our careers, and therefore having more possibilities to succeed. For talented people, they can produce more influential works. For example, if Mozart is living in today, he might compose more great songs.

  Society benefits from increased life expectancy too. When people have more leisure time, depression and stress are reduced, people's health is improved, hence people feel more satisfied with their societies. Moreover, having people work for a longer time will increase productivity and total GDP.

  But living longer is a double-edged sword. There also are negative effects.

As the number of years spent in retirement increasing, financial problems has emerged. Retirees have a greater risk of outliving their savings, and need to have more money than before to support their retired life. Pensions which supported by governments, companies and other organizations have to rise.

  However, it is not only money that is costing more. When people live longer they eat more food, drink more water, use more sustainable energy etc.. The consumption of society is growing and increasing.
