On the topic of gender preference, I remember looking at a gender ratio world map and couldn't help but notice countries where male babies are the preference tend to have more males
notice china's one child policy resulted in more male babies... Clearly not natural, God knows what was happening to the female babies.
Note, most countries in the world have more women than men because women have a higher life expectancy.
Although we all laugh that my aunt was determined to have a girl, I wonder how it made the rest of the boys in the family feel..
