I've got good and bad

This old man visits his doctor and after a thorough examination, the doctor tells him, "I have good news and bad news, what would you like to hear first?"
Patient: Well, give me the bad news first.
Doctor: You have cancer, I estimate that you have about two years left.
Patient: That's terrible! In two years, my life will be over! What kind of good news could you probably tell me, after this?
Doctor: You also have Alzheimer's. In about three months you are going to forget everything I told you.
