A health magazine presented results of a recent study that analyzed data collected by the U.S. Census Bureau in 2000. Results reveal that both men and women in the United States, heart disease remains the number one killer, victimizing 500,000 people annually. Age, obesity, and inactivity all contribute to heart disease, and all three factors vary considerably from one location to the next. The highest mortality rates (deaths per 100,000 people) were in New York, Florida, Oklahoma, and Arkansas, where...
