Pedometer and video editing

Have just invested in a pedometer in order to encourage me to get away from the computer. 10,000 steps are recommended a day, that sounds like an awful lot of walking. Still, I need it. For the past couple of weeks I have been tied to the computer, editing my work from the Royston Road Project. Have got to reduce nearly 8 hours of footage to a maximum of 20 minutes. Help! need to do some walking to mull over ideas.
