“Studies have found that the same areas in the brain that light up in imaging scans when we break a leg are activated when we split up with our mate. As part of a reaction to a breakup, our brain experiences the departure of an attachment figure in a similar way to that in which it registers physical pain.”

“Oxytocin, a hormone and neuropeptide ... plays a major role in attachment processes and serves several purposes: It causes women to go into labor, strengthens attachment, and ... [increases] trust and cooperation. We get a boost of oxytocin in our brain during orgasm and even when we cuddle -- which is why it's been tagged the "cuddle hormone." How is oxytocin related to conflict reduction? Sometimes we spend less quality time with our partner -- especially when other demands on us are pressing. However, neuroscience findings suggest that we should change our priorities. By forgoing closeness with our partners, we are also missing our oxytocin boost -- making us less agreeable to the world around us and more vulnerable to conflict.”

“The trick is not to get hooked on the highs and lows and mistake an activated attachment system for passion or love. Don't let emotional unavailability turn you on.”

“experiences are only meaningful when shared with others”

“There are many charming, intelligent people out there who can make you happy, but there are also many who are not right for you. The only way to make sure that you meet potential soul mates is to go out with a lot of people. It's a simple law of probability -- the more you meet, the greater the chances you'll find the one who is a good match for you.”

“...mismatched attachment styles can lead to a great deal of unhappiness in marriage, even for people who love each other greatly. If you are in such a relationship, don't feel guilty for feeling incomplete or unsatisfied. After all, your most basic needs often go unmet, and love alone isn't enough to make the relationship work.”

“Whether plain or gorgeous, we've learned to appreciate [secure-type people] for what they really are -- the "supermates" of evolution -- and we hope that you will too.”
