text: To conclude, using a cell phone while operating a vehicle is illegal for a reason. When someone chooses to text and drive (or call and drive), they are putting a families life at risk, as well as themselves. Even if no one is hurt or dies, there is still the car accident they have to deal with. Cost and insurance will be a nightmare for them. In general, avoid looking at text or answering phone calls while driving. It only takes a split second for an accident to occur.          It would be awsome to identify human emotions,and knowing what students feel in class can be really useful.
