Twelve is quite a prolific number. The revered clock has twelve hours displayed on its face, there are twelve months in a year, and twelve people sit on a jury. Every twelve minutes, there is a television commercial, a car is stolen, and another name is added to the national organ transplant list. But these pale in comparison to another event researchers say occurs every twelve minutes in the United States—a person dies, primarily because they lack health insurance and cannot get the medical care they need.
