Why We Kiss

This is a bit late for Valentine’s Day, sorry, but it’s still news worth sharing.

Have you ever wondered why we kiss? Logically, it doesn’t make sense; mouth-to-mouth contact is a great way to spread germs, which would seem more of a danger to the species than the pleasure of the contact. So there must be a good reason to risk catching someone else’s diseases.

Science to the rescue! There are actually many very good reasons to kiss. The best explanation, including a bit of history, can be found by watching the video at “Science Explains Why We Kiss,” https://earthsky.org/human-world/video-the-science-of-kissing?.

Happy belated Valentine’s Day!
