The New York Times recently published a great article about running. I have always said I do my best thinking while running. The article talks about other endurance sport activities—biking and swimming—which also work for me but not as well. Why? I speculate that the brain needs to compute a number of other factors while biking and swimming that deal with personal safety and have the potential to cloud thinking. Anyways, focus on an issue and run! Run until you solve it. Forest Gump did.
