Happy Valentines Day. This entertaining video from the Public Broadcasting System in the U.S. explaining (maybe) why we kiss is more or less about love. You can decide for yourself just how much is “love” and how much of it is — well — you know. The question ultimately goes unanswered because so much of what we do is about “you know” and the best explanation for that is because it’s how we’re made. Enjoy the day and be nice.
