This is written by a psychologist, Barbara Frederickson PhD, who creates lab experiments to understand human emotions, in this case, love, and what it means to us from a physiological point of view.
I think in NB we often feel like we've been burnt by love, and then if we don't have an SO sometimes we feel be deprived of love and sometimes not, we also learn to love ourselves. I am finding this a particularly helpful book in view of all that.
frederickson says that from the point of view of our body, our physiology as measured in lab tests, love is not about romance, it is not about commitment. It is about micro moments of connection with another human being. It could be a friend, a coworker, a lover or a complete stranger. It's when there is a shared moment of positive emotion that resonates. It changes our brain chemistry, it changes the physiology of the heart in a healthy way.
She shares lab experiments that led to participants having greater experiences of love in daily life and how that improved their lives overall.
It's an odd title...Love 2.0...but I guess that it means its time to update our concept of what love is... And that sure seems like what we are doing here in NB.
