>> thomas edison did terrible in school, got beaten in school, and we would say he had an amazing mind. >> larry: how do we separate them, let's say on obesity. >> the mind-body dualism goes too far back. millions and millions of years went into our brain development and we develop in such a way to maybe live maybe to the age of 20 that will increase our probability of surviving, things 20 that will increase our probability of surviving, things that we crave and are deeply rewarded in our brain system. i don't want to get too heady on your guys. the brain has many different systems there's a rash system, an emotional system and the system gets very -- and that can trigger an addictive process. >> does the stomach tell me i'm hungry or the brain? >> it's your brain that tells you you're hungry. but we think of the stomach as our second brain because your intestinal tract actually produces more chemicals that work on the brain than the brain does itself. so your body is really one system. i think of your brain as the supercomputer that is running everything, but it's all kper connected.
