“The Zombie Walk happens when I get so engrossed in my thoughts that Iâ€™ll begin pacing around the house in a semi-conscious, meditative state. Iâ€™ll walk to a window and stare outside for a while, then Iâ€™ll wander in circles around the living room, then Iâ€™ll pace into the library and stare at the bookshelves, then Iâ€™ll walk back and forth through the kitchen. This goes on without any real awareness of what Iâ€™m doing. My mind is totally focused on the problem, oblivious to the fact that Iâ€™m wearing a groove into the floor. To amused observers it appears like Iâ€™ve become a Zombie. “
In my house we call this “code mode”.
