Description
Kissing also comes with the added benefit of exchanging commensal pathogens, according to Professor D’Aquisto.
“These bugs constitute our microbiota: our unique mixture of ‘friendly bacteria’ that define us as unique immunological individual.
“Once again, the enriching of one’s own microbiota through kissing might serve the purpose of sharing, testing and increasing the ability of the kisser to face the threat of harmful bugs and hence favour the propagation of the species.”
And that is why we love kissing with tongues even though it’s gross.
