What is it about walking, in particular, that makes it so amenable to thinking and writing? The answer begins with changes to our chemistry. When we go for a walk, the heart pumps faster, circulating more blood and oxygen not just to the muscles but to all the organs—including the brain. Many experiments have shown that after or during exercise, even very mild exertion, people perform better on tests of memory and attention. Walking on a regular basis also promotes new connections between brain cells, staves off the usual withering of brain tissue that comes with age, increases the volume of the hippocampus (a brain region crucial for memory), and elevates levels of molecules that both stimulate the growth of new neurons and transmit messages between them.
Any work that requires a problem solved or a touch of creativity is more often than not solved when I am on my feet. At one job, I used to slyly punch the clock, or in this case give a thumb print, and then go for a long one hour run where I would solve (or attempt to) the problems of the day. I tried to involve colleagues in this habit, under the guise of coming up with new product ideas, but for some reason running 10k first thing in the morning was not attractive to many. At another company, since were in the R&D department we had the luxury of a late start to our work day (9AM). This meant that I had a few hours to be mired in all kinds of problems, and the lunch hour to repeatedly walk around the block trying to solve them.
Sitting at a desk typing at a computer for an extended length of time is like death to me. It’s a place for production, more than anything else.
