HOLMES: Well, a new study saying life expectancy in the U.S. is lagging behind most industrialized nations. Here now, our senior medical correspondent Elizabeth Cohen.</s>ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: T.J., researchers at the University of Washington took a look at life expectancies in countries around the world. And they wanted to see where the people have the shortest and longest life expectancies. And you know what? It's kind of surprising. What they found is that the U.S. ranks number 38. That means 37 other countries have life expectancies longer than folks here in the United States. So, let's take a look and make some comparisons. For example, the Virgin Islands, Martinique and Costa Rica have life expectancies longer than people in this country. Now, people in certain parts of the United States live shorter lives than in other parts of the United States. Let's focus in on some counties in Mississippi. In these counties in Mississippi, people have shorter life expectancies than in Honduras, Peru, the Philippines, or Brazil. Now, when you look at those other countries, you probably think to yourself, wow, I thought we had better health care here in the United States than in some of those places. And while that might true, here's the issue -- take a look at this map. This is obesity is highest in the United States, it's also where people have the shortest life span. So, obesity and also access to health care are two big reasons why life expectancies are shorter in those particular areas -- T.J.</s>HOLMES: All right. I will be back with you at the top of the hour with more live news. Right now, time for the good doctor.
