"There are two sides to every coin."

... GOOD    In my Physical Therapy, I'm "walking"--WITH leaning-help from my walker--FARTHER/"GREATER DISTANCES". BAD   ... However,  longer time walking = greater chance of my left/INJURED leg "acting up". ... Ergo, I walked--OUTSIDE--down the street--on the sidewalk--pretty FAR, until my left, INJURED leg became EXHAUSTED.  Then, I sat down in my chair.  After a brief rest, I turned my MOTORIIZED wheelchair around,stood up, PARTIALLY leaned on my walker and WALKED ~halfway-back. So, my TOTAL-WALKING distance was ~230 feet.
