What  a great TED talk! Ms. Fisher definitely knows what she's talking about. The most interesting facet of the talk to me, as it pertained to relationships, was when she described love as a motor mechanism of the brain. It's fascinating to me to think of love as something almost like food, something that we crave, something we want to work for and have. Love makes the world interesting, and as she said, if you're at the attachment stage of a relationship, makes it safe.  Ms. Fisher also said that "A world without love is a deadly place." It's interesting to consider; to me it seems as though without love we would simply operate as machines: Doing our work, producing children, living, dieing. Love is a fascinating thing and it was great to hear it described by such an interesting woman.
