Years ago, a space cloud crossed the Earth, affecting the women of the world, making them bigger and stronger. Thanks to that space cloud, the female gene became stronger, causing a decline in the birth of babies. More women are born than men. Today, women are six feet tall and very muscular. Women's immune systems also improved, making them less prone to all kinds of diseases. The cloud even affected men, reducing their size, making them, if anything, 5'6", and making their bodies feminine.
