“When you run for 30 minutes, for example, your perceived time slows down. In a busy day, a whole afternoon can go by in a flash. You need a way to control your psychological time, especially to distance yourself from normal distractions and preoccupations.

When we engage in an even longer exercise like jogging, our brain gets to take a rest from its default mode or inward-focused state—known as a self-referencing in neuroscience—and be more attuned to the outer environment. By shifting in and out of these two states of mind—reference to ourselves versus our environment—we get a new frame reference to our lives that empowers us to look at things in a different light.”
