    How fascinating! That was so much fun to watch. I learned a lot and am now an ever greater catch for guys who like smart guys. 😉

    Thorough and fascinating. I think I would kiss the narrator in 2 seconds. Just for the dopamine rush. All very scientific, of course.

    Aight. I admit it. I’m totally enamored of Joe Hanson. Cause intelligence is SOOO sexy. Now if he only has the right pheromones.

    Was there a same-sex couple in there and I just missed it? I did see a couple of fictitious aliens locking lips…

    kissing I don’t need an explanation for; but why is it so pleasurable to pick at and rip off scabs?

    @Tara He addresses that toward the end of the video, stating that most research on the kiss is focuses on college-aged “heterosexual cis-gendered couples.” Personally, I find that inclusion in a video that’s a few minutes long, pretty up-to-date.
