(NEW YORK) -- A new study of countries around the world suggests retirement could lead to reduced cognitive performance, or poor memory. Its a 20-year study by the Rand Center for the Study of Aging and the University of Michigan and involved people in the United States and several European countries, where people tend to retire younger than they do in the U.S.
Americans, who often work well into their 60s, tended to perform better on memory tests than their counterparts from countries like Italy and Spain. Richard Suzman of the National Institute on Aging says people who spend thousands of hours in the workplace benefit from the mental stimulation. It's unclear whether it's the actual work, the social interaction or other factors that might be behind a better memory.
