I only have a minute left.
We know that psychological disengagement opens the door to physical disengagement. Ageism has negative consequences to which very little attention is paid. A worker who disengages psychologically then disengages specifically by preparing for a retirement that is not voluntary, but is a reaction to a form of exclusion based on age. That means that workers who are not able to transfer their skills and who leave their familiar surroundings feeling dissatisfied become part of a whole group of discontented retirees. People in that situation will certainly not come back to the workplace, nor will they stay there.
I apologize for my long statement.
