I constantly walk with my head down. I do occasionally glance up to see the environment I am walking into, but most of the time my head is down. Sometimes, when I am walking for a long time, I start to zone out and day-dream with my head down. One day when I was walking home from the library, my thoughts were virtually engulfed in whatever I was day-dreaming about that I walked a few blocks past and perpendicular to my block!
