"My hand's working good. I can grab a jar now, and I can hold it, and I can take the lid off."
He did absolutely nothing in this video to prove he has improved at all except lift his arm about chest height. Which I don't think is any different than a few months ago. Some things I noticed:
1. He places the jar with his good hand into his bad hand which is resting against his gut for support.
2. His bad hand stays in the exact same position for this whole shot. It doesn't grasp the jar at all.
3. The jar was already open. You can tell by the sound and how effortlessly it "opens". Also notice how gingerly he screws it back on.
4. Watch how much the bowl moves while he is mixing up the slop. You can hear him grunt ever so softly from all the exertion.
5. Notice how he is already "holding" the bowl in his hand at the beginning of the clip and it ends before he removes it from the bowl.
6. Before the taste test, he uses his good hand exclusively to open the container. Understandable, but he doesn't even try to get the other one involved.
He has no useful movement in that hand. Worse, he seems to have given up on working on its functionality, despite what he says. He has to manipulate his meaty paperweight with his good hand off camera. It can hold a jar in the same sense a shelf can hold a jar.
Also LOL at the shot glass on the vinegar. That shot of apple cider vinegar a day meme isn't going to save you now, Jack.
