When it comes to occupational diseases, I think there are two meanings, one refers to the formation of corresponding occupational habits due to the long-term engagement in an occupation, which extends to other aspects of life, and becomes a characteristic of others who can recognize their occupation at a glance; one refers to the root of the disease that falls when engaging in a certain occupation. Both of these are actually very common in life, here are a few examples:
One, the teacher. The teacher's greatest vocation is to teach, because the training of students for a long time, when talking to others, but also consciously or unconsciously show the education of the gods, so long engaged in the education industry in the face of their own belief that the wrong thing consciously or unconsciously like to say said said. This has led to many people, once they see them will say, you must be a teacher! Visible this occupational disease has been deep into the bone marrow, affecting all aspects of life.
In addition to the professional habit of educating people, teachers are also really prone to many occupational diseases. For example, frozen shoulder. Many teachers because of long-term standing podium, writing slate, need to hold up the arm for a long time, have fallen into the problem of frozen shoulder. In order to spread the knowledge, they selflessly teach, so we must respect teachers.
Second, the police. When it comes to the police, what comes to mind? Anyway, the first thing that comes to my mind is the image of catching thieves and bravely fighting criminals. Therefore, the occupational disease of the police is cynicism, even if one day off the police uniform, but also away from the nosy police soul, this occupational disease has long been y imprinted in their soul.
So, there are some old retired police officers, even if they are close to old, when they see someone doing wrong, they still can't help but go up to stop, which is the best manifestation of the occupational disease.
