On the serious side, that statment was based on research done with both adult and infant males. The interesting is thing is that it suggests that, prior to any kind of cultural influence or socialization, males tend to be more interested in objects, and females more interested in people. Males don't take the time to study and understand facial expressions. I realize I'm generalizing but.... I'll leave that alone for now but it has seriously interesting ramifications.

Before they made me they broke the mold!
