text: The reason I say we should use this technology is because in the text it says "in fact we humans perform this same impressive "calcuation" every day. For instance,you can probably tell how a friend is feeling simply by the look on her face. Of course,most of us would have trouble actually describing each facial trait that conveys happy,worried,etc". What all that means is when someone is having a bad day and you wanna help them but they say they are fine but you know that she/he is not ok but how can you tell? With the technology that we have we can be able to tell all of that.
