I thought this was interesting. They didn't mention it in the video, but I thought that closing words were a nice illustration of how cuddling causes people's brain to release more oxytocin, sometimes known as "the cuddle hormone." Oxytocin causes people to bond and generally leads to people feeling safer and more comfortable. Ever felt that when cuddling? That's oxytocin. Spoiler: I also liked how when the woman felt safer she was able to open up more. Perhaps, she was even able to open up to some truth more? Barbara Fredrickson, a distinguished researcher of bonding and human being, has a great book on all of these issues, called Love 2.0. She mentions that when people open up, all sorts of wonderful things become possible. Reading her work is one of the reasons why I post that "feeding the wolves" cartoon so often. If we feed the "positive wolves," good things tend to happen. Perhaps this is why people's grandparents and teachers may have talked about the importance of a positive attitude. She also has a book called positivity, but I haven't read it. Anyway, to paraphrase a song, "human beings aint nothing but mammals" (NSFW), and, in particular, we are mammals made for social connection.
