This is a story about a fickle little hormone that plays a large role in our lives.
The name of the hormone is oxytocin, and until recently it was mostly dismissed by scientists. They knew it played a role in inducing labor and facilitating breast-feeding, but otherwise didn’t give it much attention.

Isabelle, you see, says “I love you” to everyone: to parents at her school, to people from the neighborhood, to the salesman at Circuit City.
“Oh, all the time,” Jessica says. “To Isabelle, there are no strangers — only friends she’s not yet met.”…
