I discovered this year I can run, on really soft dirt surfaces. I last about 3 minutes on concrete.
.3km that's probably more per day then the average car dependent commuter.
Think about it,walk to your car, then drive. Walk to your office, sit all day. Then walk to your car your car, then drive. Then when you get home walk to the couch, walk to the fridge, walk back to the couch, walk to the bedroom, sleep. then repeat for the next day.
