Scientists have studied the issue and done countless hours of research to come up with the radical conclusion that men and women are different.

It's a brave expert who'll chart a course through these controversial waters.

But that hasn't stopped Michael Gurian, psychologist and author of "What Could He Be Thinking?".

He believes there are about a hundred structural differences that have been identified between the male and female brain.

"Men, because we tend to compartmentalize our communication into a smaller part of the brain, we tend to be better at getting right to the issue," he said.

"The more female brain (will) gather a lot of material, gather a lot of information, feel a lot, hear a lot, sense a lot," he said.

Scientists say males have more activity in mechanical centers of the brain, whereas females show more activity in verbal and emotional centers.

Shocking! This is the biggest revelation since the Scopes Monkey Trial. This is the kind of stuff that would get a Harvard president in hot water. Get this man another grant.
