Actually once Shrinks grow older they learn more about the world around them. Like Max said above the Shrinks eventually out grow thier programing and develope a personality, awareness, and I.Q of thier own. Once this happens they begin to think of what the world is like out side and want to go do thier own thing, thus a care for themselves begins. As the years go on they realize that thier chances of accomplishing thier dreams/goals is almost zero and thus slowly become more and more depressed, etc.
