Around half of economically active South Koreans in their 30s to 50s believe they must work and earn money past age 65.

That's according to a new report by the Samsung Life Insurance Retirement Research Center.

Out of a thousand Koreans in their 30s to 50s surveyed, more than half of respondents believed the maximum age of earning to be older than 65.  Some believed they would have to work past 70.

At the same time, more than 60 percent believed the maximum age of employment at a company to be 64 or below.

Nearly half of the surveyed said that elderly workers have a positive impact on society compared to just eleven percent who viewed them negatively.

Respondents cited the positive effects of working into the elder years include improved quality of life, reduced poverty and better health. They named as adverse effects of elderly employment lower social productivity and heightened youth unemployment.
