"When you have serious chemistry, your body produces elevated levels of the neurotransmitter norepinephrine,” says Helen Fisher, Ph.D., research professor of anthropology at Rutgers University. “This, in turn, can make you jittery, uncoordinated, and a little accident-prone. And if you’re embarrassed by your klutziness, that’s a good sign, too! Because if you don’t care what your date thinks of you, you probably don’t think much of your date."
