"Helen Fisher studies the brain in love"

I think this is a very interesting talk. Yes, everything is brain chemistry-very difficult to explain, and sometimes no need to explain. Helen said "Almost nobody gets out of love alive". I think without love, life can be very miserable. I appreciate my mother's love very much. Although sometimes she still gets very upset about me, and loses her temper too, I know that my mother will never give up on me. Every year I see her, I think she is getting older than before because I always have so much trouble to make her worry. I'm afraid that I will have nothing to pay her back. She said if her death can add some happiness to me, she would like to die. Although it's not romantic love, I think the brain chemistry is similar. Then I start to wonder what makes us do such crazy things for someone that we love. I think I had very few experiences like that as I hadn't been in a good condition to like or love someone. However, in the talk, it says "Romantic love is an obssession." I think when we are in love, it's very difficult to explain why we crave to be with the one we love. We sometimes think that we want the one we love to be happy only because we think we love him or her, but in fact I think it's also because we will feel happy too if he or she is happy. Maybe biology somehow plays an important roll too.
