Mind-body connection

"How can your brain trick your body when your brain is part of your body?"
- Thumper

Thumper asked this question the day after we had been to the supermarket and BallFiend had walked past tubs of peanut butter on the shelf. He started coughing and said he thought he was having an allergic reaction (he is actually allergic to peanuts). I explained how our brains can think that something is happening in our bodies and that can cause the feeling that it is happening. Obviously Thumper was listening carefully at the time.
