See? Kissing is Science!

Just a little bit of science from Dr. B on WWJTD, talking about research related to why we go about tasting one another. This is some interesting stuff, discussing how kissing is a human way of gauging suitably based on chemical signals, which largely replaces scent-based systems many other animals use.

No, this knowledge doesn’t make kissing any less interesting to me. It makes me want to test and see if I’m more aware of the chemical exchange now.
