oldman and Rousin Z

my subject reminds of me one painting and one animation related to the elderly.

vicent van gogh "oldman" - passiveness - "being cared"
Katsuhiro Otomo's "Rousin Z" - active - "care"
(what is the "Rousin Z"?http://www.rottentomatoes.com/m/roujin_z/about.php -)

i was trying to make a concept diagram.
i got back to get a definition of a diagram.

diagram
....Generically, a diagram is a graphic shorthand. though it is an ideogram, it is not necessarily an abstraction. It is a representation of something in that it is not the thing itself. In this sense, it cannot help but be embodied. it can never ve free of value or meaning, even when it attempts to express relationships of formation and their processes. At the same time, a diagram is neither a structure nor an abstraction of structure. While it explains relationships in an architectural object, it is not isomorphic with it. .........
