Did that work differently than stretching exercises with rubber bands on fingers? (I haven't seen him doing that finger-touching move in quite some time, and yet I see him do enough hand strengthening exercises, that I am now confident if I ever need a lid off a jar again, I can ask him. His hand strength has surpassed me. I don't know if he thinks he's back to his old strength though. At the rate he's going, I can see him stronger than he was, which again, means he'll have to be careful when tightening lids and pipes.)
Also, he's stuck with dead-pinkies. They work better than they used to. (He can move them a bit by now.) But it's much like having a prosthetic sixth-finger. They're completely numb and feel like a foreign object placed there for no particular reason.
I never realized how much easier it is to eat with utensils held like pencils instead of like trowels. Somehow the food gets to the mouth more often than it lands on the floor, if it's done like we were taught when we were kids. (I always thought that was like sticking your pinky out when drinking tea. Not so much common sense, as it is about impressing others with our refinement. lol)
