Love is in the air in the lead up to Valentines Day and while we're all for hearts and flowers, there's nothing fun about the down side of the L word. If you've ever had your heart broken, you'll know that it is zero craic and a situation most of us try and avoid if at all possible (of course Ben and Jerrys and Bridget Jones are always on hand in times of need). Neuro-ethicist Brian D Earp is co-author of a study published in the Cambridge Quarterly of Healthcare Ethics. This piece argues the point that"pharmaceuticals or other emerging technologies could be used to enhance (or diminish) feelings of lust, attraction, and attachment in adult romantic partnerships. ‘Such interventions could conceivably be used to promote individual (and couple) well-being". Neuro-ethicist Brian believes that a "cure" for love could be of benefit in some cases. "You can imagine a situation in which a person's experience of love is so profoundly harmful, yet so irresistible, that it undermines their ability to think rationally for themselves. "Some people in dangerous relationships know they need to get out, and even want to, but are unable to break their emotional attachment".
