"Over the past few decades, 160 million women have vanished from East and South Asia — or, to be more accurate, they were never born at all. Throughout the region, the practice of sex selection — prenatal sex screening followed by selective termination of pregnancies — has yielded a generation packed with boys. From a normal level of 105 boys to 100 girls, the ratio has shifted to 120, 150, and, in some cases, nearly 200 boys born for every 100 girls. In some countries, like South Korea, ratios spiked and are now returning to normal. But sex selection is on the rise in Eastern Europe, Southeast Asia, and the Middle East."

Why aren't men and women becoming more alike? A husband and a stay-at-home wife in a patriarchal Botswanan clan seem to be more alike than a working couple in Denmark or France. The more Venus and Mars have equal rights and similar jobs, the more their personalities seem to diverge. International Sexuality Description Project findings.

The Ladder Theory... a theory of adult male/female interaction. While some may find this a bit offensive, it is quite interesting. It includes rating systems, attraction breakdowns, scenarios, consequences, and manifestations.
