Grey Matter

I was reading this interesting article regarding brain composition in men and women.

They found that in intelligence tests men use 6.5 times as much grey matter as women, but women use nine times as much white matter.

Grey matter is brain tissue crucial to processing information and plays a vital role in aiding skills such as mathematics, map-reading and intellectual thought.

White matter connects the brain's processing centres and is central to emotional thinking, use of language and the ability to do more than one thing at once.

However, I found this particular finding the most revealing:

Women can speak 20,000 to 25,000 words a day compared to a man's 7000 to 10,000.

Which says a lot. If you're a woman.
