PS Apparently some students of science are prone to a more comprehensive view of "love" though - Love in the Brain

Clara begins, of course, with the standard scientific focus on stinky t-shirts and brain chemicals, but at least she concludes with

"Although it is your partner's brain that enables them to act or say those things that trigger your brain to respond with those chemicals of attraction and attachment, everyone's brain is individual and makes up an individual "you" and that unique and special experience that we call love. Although this does not rule out other areas that many believe play a role in love, such as the soul, it shows that the brain does play a vital, if not ultimate role in all aspects of love and that this role is extremely complex and unique."

Sheesh -- I wonder if they flunked her for daring to entertain a concept like "soul"!
