CPR—or cardiopulmonary resuscitation—is a life-saving procedure that forces oxygen-rich blood through a body in which the heart has stopped. A person is not “dead” until his or her brain has died, which happens after about six minutes once the heart has stopped pumping blood through the brain. When a qualified person does CPR, he or she presses on the patient’s chest, squeezing the stopped heart between the breast bone and the spine, which forces blood through the body. Between each series of pumps, the rescuer breathes into the victim’s mouth, sending fresh oxygen into his lungs and into the blood. Many people are alive today because of CPR. *************** After someone's heart has stopped, _____.

In the late 1980s, concern about the deadly effects of illegal drugs became a top national issue.

These drugs do have a terrible effect on individuals and society, but the facts about them are somewhat different from their popular image. Each year, about two thousand people due from heroin overdoses, and about three thousand die from cocaine-related causes. At the same time, 50, 000 people die every year because of alcohol—including thousands of innocent victims of drunk drivers. Additionally, a third of a million people die every year from cancer due to smoking cigarettes.
