People spend a huge part of their lives at work. Suddenly, in the later years, they are no longer able to do that work. Because their job was their focus for so long, many fail to build other types of hobbies or activities. The job is all they know.
It is important to provide bridges for individuals so they are able to communicate, in the present, their jobs of the past. Providing for this exchange can lead to other social interactions or, at the very least, a positive connection to the therapist who is willing and interested in listening.
