When we watch a seventy-year-old hand move, we feel, “Yes, that hand has lived.” All the bodies it has touched, all the weights it has lifted, all the heads it has cradled are present in its movement. It is resonant with experience; the fingers curve with a sense of having been there. Whereas in a child’s hand there’s a sense of just arriving. The child’s movement is pristine and innocent and delightful, but a truly supple adult movement is awesome, because all life is included in it.
