Obesity is contagious, according to new research published in the New Englad Journal of Medicine. In an analysis involving 12 thousand people, the study found out that when a person gains weight, his close friends also tend to pack more lard around the waist - people are more likyly to become obese by 57% when a friend becomes one.This does not mean that people should start avoiding fat friends, as the same holds true for weight loss too, and, as the lead researcher had emphasized, having friends are good for one's well being too.
