Yes, very good question. I haven't gotten that one either. But I really, it's an opportunity for me to talk a little bit about it. Patients who take antipsychotic medications, and I can tell you, as someone who prescribes them tend to gain weight very quickly, and it is often very difficult for them to lose it no matter what they do over time, and yet they have to take their antipsychotic medication. As I sort of think about patients with schizophrenia, sort of routinely say, the worst thing a patient with schizophrenia can do is not take their medication. And second worst thing they can do is take their medication, because these medications really do cause serious, serious metabolic problems. And yet, for the purposes, which are very good at reducing psychosis, they're quite effective. So we're doing the study. I know no one's ever done, sometimes either of these two studies, which is, can you reduce the weight gain caused by antipsychotic medication at all, and insert the news, the early study are people who you can really track to the very beginning when they began their antipsychotic medication, it's within the last six months. Can you actually take away that weight gain, or take a look at the other group of which the numbers in the United States are, are really ample of patients who have taken antipsychotic medication for a long time and have substantial weight gain, but are little, potentially a little less specific to the antipsychotic medication, because they live their life in America and American diet, and so on, and so forth. So I don't know what the results of these studies are going to be, obviously, I have a hypothesis that our medicine will be beneficial for both of those groups. But as Bill mentioned before, much data that come and it's going to be very, very interesting, both for us, and for the field to see if we can really do something about this problem, whether it's a short term problem or a long term problem. It's a big problem. And I really look forward to seeing that turning over the cards in these blinded studies.
