Gravely ill, a man was examined by a doctor while his wife stood by.
After the examination the physician motioned for her to meet him in the hallway.
“Your husband is very sick, “the doctor said. “but, you can do three things to ensure his survival:
First, fix him to eat three healthy meals a day. Next, give him a stress-free environment and don’t complain about anything. Finally, have sex and oral sex with him every day. “
The doctor left and the woman returned to her husband’s room.
“What did the doctor say?” he asked.
“I’m sorry, m’dear, “she said, “but he said you’re not going to make it. “
