As if the idea of catching bird flu isn’t bad enough, now it looks like you might be able to catch being fat. A study done at the University of Wisconsin found that certain viruses may cause obesity, meaning obesity can be contagious. A group of chickens were given human adenoviruses. Those who got certain viruses had much more body fat compared with the control group, even though they didn’t eat any more. While the researchers don’t know if this will hold true for humans, just to be safe you might want to watch what you eat, get plenty of exercise, wash your hands after touching a fat person, and don’t kiss any chickens. Hey, you can’t be too careful, you know.
