TED 2006
Helen Fisher 1: Why we love, why we cheat  (script)
Summary
After reading this article, I noticed that this article had announced 10 years ago. Thus, l'm just living there when is in the biggest social trend that the speaker said. It means that in the article, she said two most profound social trends in the coming century: women working is going to be the workforce and the aging of world population is advancing. And then, it's going to have an impact on our important brain systems: lust, romantic love and deep attachment to a partner. It shows that women have their sexual expression more and it seems to be seen that they desert an important generative function.  She said that it means that it's returning to an ancient. Furthermore, using antidepressants tampers with those brain systems.
I don't think that it's progressing in a good direction, she didn't tell us this, though. However, she said that a world without love is a deadly place.
Why we love, because millions of years ago, the circuits of evolved the sex drive, romantic love and attachment to a long term partner, are deeply embedded.
