Ancient lovers believed a kiss would literally unite their souls, since the spirit was said to be carried in the breath.

Now we might not believe that anymore but we’re no less enamored with the kiss these days. You just need to see the reams of movie kissing sequences on YouTube to get a taste of our obsession with a good smooch. So in the name of research I’m going to Georgetown today to talk about the highs and lows of a proper snog.

Special thanks to all of my interviewees and Café La Ruche in Georgetown.
