A 70 year-old woman went to the doctor for a check up. The doctor told her she needed more cardiovascular activity and recommended that she engage in sexual activity three times a week.
A bit embarrassed, she said to the doctor, "Please tell my husband."
The doctor went out into the waiting room and told the husband that his wife needed sex three times a week.
The 75 year-old husband asked, "Which days?"
The doctor answered, "Monday, Wednesday, and Friday, would be ideal."
The husband said, I can bring her Monday and Wednesday, but on Fridays, she'll have to take the bus."
