If a potential mate has managed to pass all these tests, there's still one more: the infamous first kiss, a rich and complex exchange of tactile and chemical cues, such as the smell of one's breath, and the taste of their mouth.
Ako je potencialni partner i uspio proći sve ove testove, preostaje mu još jedan ozloglašeni prvi poljubac, bogata i kompleksa izmjena taktilnih i kemijskih signala, kao što su miris nečijeg daha i okus njegovih usta.
