Walking is part of my daily work routine. Usually around 2~3pm I go out for a ~45 minute walk. I use this time to think about work related problems, solving them in my head as I go. Sometimes a walk can be much longer, if I'm stuck at a particularly difficult problem. I consider the walk routine as work, so I also charge my customers for this time. They are OK with that though, since they understand that thinking about their problems is what they pay me for. Unfortunately I can't walk from home to my office, it's too far, so I ride my bicycle. The bike ride (circa 20 minutes) is perfect for clearing my head after the work day, and switch from work-mode to relax-mode.
