Well, not so fast.
Researchers from the University of Leeds found that kissing may have started as a technique to spread germs, and thereby boost your body’s immunity to illness.
Specifically, a germ called cytomegalovirus lives in saliva and is passed from man to woman during a kiss. While cytomegalovirus is normally harmless, if a woman catches it while pregnant it can kill the unborn baby or cause birth defects.
Kissing the same person for about six months appears to offer the best protection against this bug, researchers say.
