"Riddle me THIS. Riddle me THAT."

...--The Riddler, 'Batman Forever' So, my Physical Therapist stretched my FINGERS on my left HAND.  THIS limb-manipulation SOMEHOW improved my WALKING--WITH my walker.  (At the end of my session my Physical Therapist said that THAT was my BEST WALKING!) Ergo, HOW could/did "relaxing" my fingers IMPROVE my walking--with my FINGERS? ... My Physical Therapist concluded--and I concurred--that stretching and relaxing my fingers will STOP my diverting my attention AWAY from my "walking" and ONTO my sweaty, sliding hands.   So NOW, I must stretch my fingers DAILY.    In conclusion,  YAY, SCIENCE/PHYSICS!
