Like anyone who likes to immerse himself in a good book, I believe that reading can engage both the mind and the body.
To test my theory, I developed a device, which I call the the Reading Response Recorder. The RRR quantifies the degree to which a book engrosses me by measuring my galvanic skin response, heartbeat, and blood pressure while I'm reading.
For more visceral reader responses, there is also a line fed through my sinuses, down my esophagus, and into my stomach. By monitoring its bile levels, the RRR can detect if an author’s prose is causing my gorge to rise.
Pictured below, we see the RRR issuing its first bile alert! (I set the book down. Then I felt better.)
