No need to go back in history. Visit a psychiatric hospital, see those poor souls on first generation antipsychotics still in use. They walk around like zombies, slowly, with a parkinsonian gait. Staring vacantly or grimacing, some have their mouths constantly open and drooling (look up tardive dyskinesia). But hey, as long as they are docile, right?
