I will answer very quickly.
Some research has been done on accommodations that must be made to take into account the changes in physical condition, the quality of attention, cognition and mental health as people get older. There is a lot of information missing. That is why a few months ago, we launched—and this is just a coincidence—a study, intended to lead to a strategic initiative, on the conditions that would encourage workers to stay on the job despite the job requirements that do have an effect on health.
There is a lot of information that we still do not have. We have to acquire more knowledge in this area.
