A prostitute visited a colleague in the hospital just before she was about to have a heart transplant.



Concerned about her friends welfare, the prostitute went up to the surgeon and said, Doctor, Im worried about my friend. What if her body rejects the organ?



The doctor replied, Well, shes 34 years old and is in extremely good health, apart from her heart. How long has she been in the business?



The patients friend replied, Shes been working since she was 18 years old, but whats that got to do with anything?



Well, said the doctor, if shes been working for 16 years and hasnt rejected an organ, I dont think shes about to start now!
