I was reading Time Magazine's articles about brain function, and how to improve it. It was fascinating and thought provoking, and I moved nearer and nearer the window for better light. I was improving my own brain power, but I was interrupted by a spasm of uncontrollable coughing.
I had moved right into the flow of forced air from the airconditioner. I had a flash of intuition: move away from the airstream.
Coughing stopped. See how reading improves your mind?
