That's insightful.

True, the Hands basically, are clamps. They're smart. They get all of the other components to do the work.

I suppose that it is so natural for human beings to manipulate that it is hard work not to do anything with them. Being so important for us human, I guess a large fraction of the brain is devoded to "hand feel and conciousness" compared to say the right forearm, so it would be both important to monitor they don't interfere and easier to monitor than say the wrists per se.
