This is a great article regarding 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 with biking and swimming that deal with personal safety – so that has the potential to cloud thinking. Anyways, focus on an issue, and run! Run until you solve it. Forest Gump did.
