and at the other end of the age group
A very old woman went to the doctor for check-up. The doctor told her that she needed more activity and recommended sex three times a week.
She said to the doctor: "Please can you tell my husband." The doctor goes out in the waiting room and tells the husband that his wife needs to have sex three times a week. The 80 year old husband replies: "Which days?" The doctor says, "How about Monday, Wednesday and Friday?" The husband says, "I can bring her Monday and Wednesday, but on Fridays she'll have to take the bus."
