There aren't a lot of positives about being overweight, but a study by the University of Michigan shows that there could be one reason for the chunky among us to celebrate. U of M studied 300,000 traffic fatalities obtained from the National Highway Traffic Safety Administration between 1998 and 2008, and it has reportedly found that overweight people had a 22 percent lower fatality rate than underweight people. However, the story changes for the worse if you're a man with a Body Mass Index (BMI) of 35 to 50 and you are not wearing a safety belt. The study shows that obese men are 10 percent more likely to die in an accident if they don't buckle up.
