Finnish scientists have concluded that the ratio of the width to the height of the face makes it possible to predict how many children a person will have. According to John Loehr and his colleagues in the journal Biology Letters , for their study they have been based on the analysis of the shape of several hundred male faces of soldiers who participated in World War II , in addition to collecting some personal data from the combatants. This is how they discovered that men with broad faces tend to have more offspring than those with narrower faces. In addition, the data analyzed indicates that the sharper a face is (taller than it is wide), the greater the range that a soldier usually reaches .
The study did not detect important relationships between survival rate, aggressiveness, and face measurements.
