5 Scientifically-Proven Ways Kissing Makes You Healthier

A recent study reported in the journal Medical Hypotheses says kissing may increase a woman's immunity from Cytomegalovirus.

Otherwise, the bug is relatively harmless in adults. Kissing has long been thought to be a way to pass along bugs and thus strengthen the body's defenses. [Photo via @evevalentino]
