text: In the text it states that the facial expressions for each emotion each universal observes Dr. Huang ,so that means he can se every thing you are feeling .THE Text states that to an expert , faces dont lie ; these muscle clues are sometimes used to spot when a smiling politician or celebirty isn't being truthful . This are other reason why i dont perfer technology reading people faces .But i also have a good thought on technology reading people faces . One reason is that when a kid get in trouble at school and lie about something he did the teacher can get the computer and tell if he is lieing . It also tates in the story the it can tell if you are being truthful .
