text: Lastly, if you should take your friends or peers advises. If you do you should use these steps. First you should ask and note what they said as their opinion see which one was more used (if they chose that you should wear or use this one better than the other one), than if they chose this one over this one you would chose that one. If you don't, you go with whatever you like.The Facial Action Coding System (FACS) could be useful for people that are not around you enough that you have no idea what they are feeling but in most cases most people can tell when their friend is feeling down or not."In fact, we humans perform this same impressive "calculation" every day. For instance, you can problably 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, ect. Yet Dr. Huang observes that artists such as da Vinci studied human anatomy to help them paint facial muscles precisely enough to convey specific emotions. His new computer software stores similar anatomical information as electronic code." This shows that most people do not know the specific traits that describe the emotion but most people also know that when their friend or family memeber makes a certain facial expresion that they are either happy, sad, mad, or even annoyed.
