I don't know if this is true but I read that people studied who was more intelligent, Boys or Girls. It ended up that boys have less brain than girls below the age of 16, same as girls from 16 to 21, and 10% more brain than girls after 21 years old. So after all boys end more intelligent than girls in the end. But there was another thing. Boys are good on solving complicated things and study more Math, Physics or Engineering. Girls have more logic than boys and are better in the daily life.
