Austria, the birthplace of Freud, is also home to a Museum of Contraception and Abortion. According to one of the museum's displays: "After having sex, the man is to stay in bed while the woman should get up and run in a circle around the room three times and complete 10 deep knee bends after each lap. It apparently does not matter if the woman runs clockwise or counterclockwise, but running swiftly in a circle and breaking to do knee bends was, as late as 1928, prescribed as a form of birth control." Just like making sure you're on top, because when a woman's on top she can't get pregnant. That's just science. [The Smart Set]
