Not only is smoking cigarettes a disgusting smelly habit, it’s also extremely bad for your health. It has been proven to cause cancer, lung disease, and heart disease, and to weaken your immune system. Smoking makes it a lot harder to breathe, which means it’s more difficult to play sports and get the exercise you need to stay healthy. It is also harmful for those hanging around a smoker, because they breathe the smoky air. Even though most people are aware of how bad smoking is for them, more than 1,000 people die each day from its effects!

10. FIND THE SUPPORTING DETAILS
There is some evidence that colors affect you physiologically*. For example, when subjects are exposed to red light respiratory** movements increase; exposure to blue decreases respiratory movements. Similarly, eye blinks increase in frequency when eyes are exposed to red light and decrease when exposed to blue. This seems consistent with intuitive*** feelings about blue being more soothing and red being more arousing. After changing a school’s walls from orange and white to blue, the blood pressure of the students decreased while their academic performance improved. (DeVito, qtd. in McWhorter 136)
*The way in which a living organism or body part functions.
**The breathing process.
