If you think it is unlucky that the nurse card is not tied to illness, it may be because you have tied health to the nurse card, and not being sick means that you don't need to use the nurse card. However, insurance essentially exists to deal with accidents and risks, not just to pay attention to diseases and medical care. Therefore, from the insurance point of view, not getting sick does not mean that the nursing card is useless or unlucky. On the contrary, it means that you are healthy and have no health risks.
Most importantly, everyone will interpret images and symbols differently, so your feelings may be related to personal beliefs, values or culture. If you feel uncomfortable or unlucky about the care card, you can contact Pacific Insurance to find out whether there are other health benefits plans that can meet your needs or find other insurance products that meet your values.
