Weird day yesterday. The security guard at work decided I have a girlfriend because I rushed to my car instead of hanging around to chat. Of course, he says not to have children because they ruin everything.
Next, a woman I only really know from conversations on Tumblr suggested a couple Helen Fisher books. I told her about Loneliness where Cacioppo says social isolation causes pain in similar parts of the brain as physical pain. Fisher talks about love occupying the same parts of the brain that cocaine manipulates.
If the below video does not work, then try Helen Fisher: The brain in love.
