Science explains why we kiss
You kiss your romantic partner, your children, and even your pets, but why? Educational YouTuber Joe Hanson of the series It’s Okay to be Smart explains in this video.

Henson goes on to explain that 90 percent of all human cultures kiss. We have records of kissing going back 3,500 years. So, kissing is part of our human heritage. It’s a complex biological act, it cements relationships and it’s good for you.
