Thus, anyone using posture to assess personality, character, or psychology must first rule out possible underlying medical conditions which may be affecting a person's posture. Moreover, there is data claiming that one maintains his or her posture worse if he or she listens to the sentences which describe actions of others. For example, if your task is to maintain your posture rigorously in a state you do it worse when you listen to sentences like these: "I get up, put on my slippers, go to the bathroom".[23]
