Why We Kiss (NPR)


Why do humans kiss? Do we risk contracting a virus hidden in our partner’s mouth simply for love or do we kiss to achieve some other goal? While findings by psychology graduate student at the University of Oxford, Rafael Wlodarski, support two of the existing hypothesis; we kiss to assess potential mates and we kiss to maintain attachment to the mate we’ve found, he also says that even though kissing may result in arousal it isn’t the driving reason why people in romantic relationships kiss each other. NPR explains the findings.
