The researchers found that when allowing chocolate to melt on their tongues, subjects experienced longer-lasting spikes in heart rate and significantly more intense boosts in brain activity for all regions of the mind than when kissing a lover, the BBC reported Monday.

"A buzz that, in many cases, lasted four times as long as the most passionate kiss." Lewis said the findings were consistent for both sexes. "These results really surprised and intrigued us," he said. "While we fully expected chocolate -- especially dark chocolate -- to increase heart rates due to the fact it contains some highly stimulating substances, both the length of this increase together with the powerful effects it had on the mind were something none of us had anticipated."
