You don't have a work brain and a home brain. You have a single brain, one you carry with you wherever you go. Whatever affects you in one place is fully capable of affecting you at the other.

A third or more of the brain is devoted to visual processing, not true of any other sense. We have color vision and it is truly binocular. This sophistication is not true of other senses, such as smell, where many genes are actually mutated and no longer work.

Whether at work, home or school, everybody carries their brain around them, and if the organ suffers from a disorder, we carry the disorder around with us too.

Even though we don't know squat about how the brain works, the little we do know suggests that if you wanted to design a learning environment that was directly opposed to what the brain was naturally good at doing, you would design the education system we currently have, not only in America, but all over the world!

The brain appears to have been designed to solve problems related to surviving in an outdoor setting, in unstable meteorological conditions, and to do so in near constant motion.

The ability to double our biomass - not by waiting several million years and growing to be the size of an elephant - but waiting a few hundred thousand years for neurons to sprout into our brains - ones capable of having us create emotional relationships with other members of our species. We thereby double our biomass not by getting bigger, but by creating an ally.
