text: These are all things that could cost us more than required. So next time you have to make a decision, get multiple opinions and dont just settle on good. Remember it isnt bad to ask people what they think of something so you dont mess up big time. There is always a cheaper or better option that could save you money, or make you a happier person.I think using the Facial action coding system in students in a classroom is not good and the same thime bad. The students shouldt be using that they dont know what can go wrong.
