Either way, your genes and evolution may play a major role, US researchers reported on Monday.
While it may come as no surprise that genes may help explain why some people have many friends and others have few, the researchers said, their findings go just a little farther than that.
"Some of the things we find are frankly bizarre," said Nicholas Christakis of Harvard University in Massachusetts, who helped conduct the study.
