the science behind kissing

So after the GP paper

the first thing Claire said to me was

"Why do people kiss?"

So Claire shicheng and I spent a good part of our break discovering the science behind kissing

1) Apparently, kissing releases Dopamine, a chemical in your brain that gives you a rush and makes you feel like the queen of the world

2) Kissing is a reflection of breast feeding (because of lips sensations i guess) so we associate it with love, attachment and warmth (and nourishment? all you need is love)

Other stuff i found out later was:

3) Kissing lets you smell your other person better which can help you know how great or not great they are

4) Eskimos kiss with their noses (i used to do this with my mum, when i was a kid and she put me to bed. Or sometimes there'd be the butterfly kiss which meant fluttering your eyelashes against someones cheek like a butterfly's wing)

5) It burns calories!

6) it feels good (that was my initial answer, and i guess you can't argue with it haha)
