 I, at one point, was developing in one of my areas, clinical trials, maybe 10, 12 years ago, a nasal spray of a long-acting oxytocin. So oxytocin is the hormone that's responsible for bonding. You know, it is raised up. So my concept was, the hypothesis I was working under was, okay, we will give the children this. They will get about two hours of very high levels of oxytocin in their brain.
