Bonn, Germany - Retirement once meant imminent death in many cases. People stopped working at age 65 and some dropped dead a few months later.

"This was a much greater problem in former times," remarked Uwe Kleinemas, director of the Centre for the Cultures of Ageing at the University of Bonn. Thanks to improved working conditions, people today were no longer so physically exhausted at the end of their working lives.

Kleinemas noted a wholly different problem faced by many older people, however: "They want to continue working but are not permitted to do so." This, too, can be hazardous to health.
