I guess I didn't understand what the "string" you described was for, Gil. Thought it for manipulating a dummy bird. Didn't think you had reduced yourself to that level anyway. And the scenario you mention about mobility/disability is certainly legit, though I do believe there comes a time in one's life when a man has to admit there are some things he just cannot do anymore...
