Numerous studies have shown that once we become attached to someone, the two of us form one physiological unit. Our partner regulates our blood pressure, our heart rate, our breathing, and the levels of hormones in our blood. We are not longer separate entities. The emphasis on differentiation that is held by most of today's popular psychology approaches to adult relationships does not hold water from a biological perspective. Dependency is a fact; it is not a choice or a preference. -Amir Levine M.D., and Rachel S.F. Heller, M.A. "Attached: The New Science or Adult Attachment and How It Can Help You Find-And Keep-Love."
