Kissing can boost your immune system

According to a study from the Netherlands Organisation for Applied Scientific Research, a 10-second kiss transfers as many as 80 million bacteria between you and your partner. If the idea makes you want to run to the bathroom to brush your teeth, hold on a moment.

As it turns out, germ exposure can provide a healthy boost to your immune system. "Swapping spit means swapping germs, and that is nature's natural form of vaccination," Dr. Yael Varnado, founder of Get Checked 4 Life (a nonprofit organization that provides access to health services for at-risk communities) told Match.com. "Being exposed to others' germs causes your body to make antibodies against those germs, which can in turn lead to immunity and prevent illness."
