text: If fellow citizens around the world limit the use of cars, then our environment will be less poluted as well as, less stressful. "It's a good opportunity to take away stress and lower air pollution," (Selsky, 24). Even young people are limiting the usage of cars. "A study last year found that driving by young people decreased 23 percent between 2001 and 2009..." (Rosenthal, 41). Take the initiative, and decrease polution and stress by limiting the use of cars.                                                                                 I believe that this technology is very usueful. This technologhy would be so amazing to have around, it would help students and teachers out so much. it can tell when you are bored, happy, sad, scared, worried, and can even tell when you do not like an ad. It could really help out in classrooms and other places.
