Exercise Fatigue makes cowards of us all. Early in the disease process, I had to crawl up a flight of stairs and rest twice to reach the second floor. The most difficult thing in the world was to push one foot ahead of the other. Unless you literally cannot stand up, walk. If you can only walk a hundred feet, start putting one foot ahead of the other.
Tomorrow walk a hundred and ten feet.
Keep right on going. If necessary, sit on a trampoline and bounce each day until you regain enough energy to stand. Then walk . May the road rise to meet you. May the wind always be at your back.
