This hilarious study somehow reminded me of an old feminist joke my wife likes to tell:
A man is feeling ill and goes to his doctor. The doctor asks to see his wife. “Your husband is very, very sick,” the doctor tells her, “and he’s going to die, unless he has a clean house, hot dinners and sex every night.” The wife goes back to her husband and he asks her what the doctor said. “He says you’re very, very sick,” she tells him, “and you’re going to die.”
