This important breaking science news was reported by the BBC:

When it comes to tongues, melting chocolate is better than a passionate kiss, scientists have found.
Couples in their 20s had their heart rates and brains monitored whilst they first melted chocolate in their mouths and then kissed. Chocolate caused a more intense and longer lasting “buzz” than kissing, and doubled volunteers’ heart rates.

The research was carried out by Dr David Lewis, formerly of the University of Sussex.

Dr Lewis said: “There is no doubt that chocolate beats kissing hands down when it comes to providing a long-lasting body and brain buzz. “A buzz that, in many cases, lasted four times as long as the most passionate kiss.”
