text: If this technology is in every class, then student's would just guess based on that technology to see if someone is happy or sad. Student's should use paintings or pictures to tell that person emotions. I think that the only time to use that technology is to look at the face muscles and not just telling if someone is happy or sad. If someone that I know is sad would I use that technology? Absolutely not, I'll just look at their and see if they're sad or not. So my opinion on this is don't use it for people's emotions, use it to just look at the face muscles and describe what they are. All right, to some of you people this might not sound too interesting but just hear me out. If you want a really excellent job, be a cowboy in the Seagoing Cowboy program. In fact, take it from me a cowboy who rides waves.
