Taking a stroll can do wonders for creative thinking. Just look at the great Aristotle, who sauntered about as he lectured his followers or Charles Dickens, who routinely walked for 30 miles a day. Nowadays we sit more than we sleep and it effects our health as well as our minds. According to researchers at Stanford, what we should really be doing instead of sitting is walking. The researchers found that people perform better on creative divergent thinking tests during and immediately after walking and that the act of walking itself, rather than the sights encountered on a saunter, was key to improving creativity. So if you need to get your mind running, step out the door and take a walk.
