chocolate is 'better than kissing'

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, and now of the Mind Lab.
Experts, concerned at growing levels of obesity throughout the developed world, warn that chocolate should only be consumed in moderation.
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."
The volunteers, all aged in their 20s, had electrodes attached to their scalps and wore heart monitors during the two tests.
The researchers compared their resting heart rates with those during the chocolate and kissing tests.

The study also found that as the chocolate started melting, all regions of the brain received a boost far more intense and longer lasting than the excitement seen with kissing.

Psychologist Sue Wright said: "Chocolate contains phenylethylamine which can raise levels of endorphins, the pleasure-giving substances, in the brain.
"It also contains caffeine which has a stimulatory effect on the brain.
"This would explain why chocolate can give people a buzz, and why people can become addicted to it."
