Neurologist David Lewis hooked college students up with electrodes and heart monitors and fed them dark chocolate, measuring how stimulating the chocolate was to the brains and hearts of the subjects.
Then the same measurements were taken during passionate kisses.
The results? Both heart rates and brain waves showed more excitement and longer-lasting excitement from chocolate than from kissing. Heart rates more than doubled in some chocolate-eating volunteers, and both heart rate and increased brain activity went back down more quickly after the kiss than after the chocolate.
While many question the accuracy of the study, chocolate does contain phenylethylamine, a compound the body makes on its own when people are in love, as well as theobromine, a stimulating substance rivaling caffeine.
Apparently, love rocks, but chocolate rocks harder.
