Mr. Jones, a 60-year old man has a heart attack while making love to his wife. Panicked, she calls 911. Paramedics arrive and take Mr. Jones to a hospital, where Dr. Goldman performs an emergency procedure to unblock Mr. Jones’ arteries.

Mr. Jones returns home from the hospital and, after a few days, attempts to resume the lovemaking.

Mrs. Jones refuses — “I don’t want you to have another heart attack. So, no sex until I see a note from your doctor that it’s ok for you to have sex with your heart condition.”

Mr. Jones goes and asks Dr. Goldman for such a note. The doctor obliges, writing:

“Dear Mrs. Jones,

This letter is to confirm that my patient, Mr. Jones, is cleared to resume sexual activity.

Furthermore, please be advised that the new medication that he is taking to keep his heart in tip top shape, may also have the positive side effect of enhancing his sexual performance to the level of a man half his age, so I expect that you will be very pleased!

Sincerely,
Dr. Goldman”

“Hope this works for you, Mr. Jones,” says the doctor handing over the letter.

“It is perfect! Thank you, Doc!…Though on a second thought, if you could do me a favor and make a small change — instead of ‘Dear Mrs. Jones’ just address it to ‘To Whom It May Concern.’”
