Jacqueline007: I am not feeling so good, I can barely breathe. Do you think there is something wrong with my lungs?
Doctor: We will do an X-ray, but I am sure your lungs are just fine. You exercise and you don't smoke.
Jacqueline007: Could it be my heart then? Or maybe my liver?
Doctor: You are a healthy young woman. It is just in your head.
Jacqueline007: Are you saying that there is something wrong with my brain? Or my nerves?
Doctor: You have such an imagination!
