text: The most important thing about his machine is that there has been people that committed suicede and if the machine can detect what you feel i think that it can detect those people or kids and that way thier parents or teachers could know and stop it from happening and that machine can save a life or two. The machine can be also be used for police officers that need to slove a case or thing that someone is lying so they will just have to put the machine in thier face and ask questions and that will beb a win for th epolice officers. The article also said that the drawing of Mona Lisa was not only smilling she was also, ''9 percent disgusted, 6 percent fearful, 83 percent happy and 2 percent angry''. So if that machine told them all those percents in just a smile that the painting did that is amazing.
