An elderly man was having what he felt to be poor health for a few weeks, and so finally went to his doctor. His doctor asked him to come back in a week for tests, and so the man did. A week after the tests, the doctor called the man to inform him his test results were in, and asked him to come to his office to discuss the results.
"I've got some bad news," said the doctor when the man arrived, "I'm sorry to tell you this, but you have Alzheimer's and cancer."
The man sat stunned for a moment, and then replied, "Well, thank goodness I don't have cancer".
