Kisses!! Medically sound

People who kiss more often have similar bacteria culture in their mouth. When we kiss, rouhly 80 million bacteria transfer between us and our partner, introducing new and sometimes beneficial bacteria into our ecosystem. These findings are part of a recent research that suggests there maybe a biological advantage to swapping spit.
    Twenty one couples filled out a questionnaire asking them how often they kissed. Then the researchers had each subject consume a probiotic yogurt which contained hearty sources of so-called"good bacteria". After, the couples shared an intimate 10 seconds kiss; the researchers swabbed their cheeks to check bacteria levels. The couples who reported they kissed more ofter ended up having more similar microbiota than less-frequent kissers
     "Bacteria help regulate a lot of body processes," said Dr.Alison Morris, an associate professor of medicine at the University of Pittsburgh Medical Center.
