My wife and I recently applied for CC permits. At the end of the process, you go to a business that does digital finger prints for the state. I had some difficulties, and did not get 10. The operator told me that older people who have handled a lot of paper in their lives tend to erase their finger prints. My wife, a former teacher got exactly no readable prints. I told her she could now become a career criminal. I guess I always thought your finger prints were always with you. Wrong.
