 And the first question on our list here is, what is the impact? Or can you say more about the noise? Can you say more about the role of intestinal flora? That took me by surprise. And I realized it was in our paper that we submitted and that some people will have read. So for those who didn't, the evidence is that the bacteria in your gut when you're developing actually changes the way your brain develops. This was a study done by one of our former colleagues who's now at the Carroll Institute in Sweden, Rucheles Heinz Diaz. And the idea here is that they could manipulate in their lab animals the different bacteria that were in the gut. And they could show changes in the development of striatum and prefrontal cortex. This is new stuff. This was just published recently. It's provocative because it tells you how insidious some of these early developmental effects can be that you are what you eat or you are what things inside you eat. And we really know a lot about diet. We know that diet makes a difference to brain development. I think that we don't know a whole lot yet about the nature of these bugs in your intestine and how they change brain development, apparently they do. And so you begin to see that it's a whole brain controls everything. And in some, the brain's controlling the whole body. But there's this idea that the brain evolved from the gut, which seems pretty disgusting. But in a sense, the gut has all of the same controls on it that the brain has on it. And so it's not surprising that the two are going to interact. So that's the first question. Sorry, I can't tell you more about it because it's just all so new. Robin? So the next question was about same sex marriages and the effects of these various roles and how that would affect brain development. And clearly, when I mentioned that moms tend to be this way and dads tend to be that way, that's the average. And of course, there are people who are on either end of that distribution. So again, providing your children with the most diverse kinds of parenting is ideal. But there are organizations like Big Brother and Big Sisters who if you don't feel you have a strong male role model, you could encourage your children to join these groups. There's also grandfathers, uncles, and close neighbors, early childhood educators, as I mentioned, that could be that strong male attachment figure. Clearly, this has not been well studied. But when we look in Daegu's, and I showed you what happened if the father's taken out of the cage, if you replace father with another female, the effects are the same as for just mother alone. So it doesn't reverse the status of the brain back to having paternal and maternal effects. It really does require something about a male attachment figure for these brains to develop in an appropriate way. But that's not to say there aren't some females who embrace more of the male modeling of parental behavior and that there aren't some males who embrace more the female modeling of parental behavior. I, for example, my husband is more the safety net. He's always worried about whether the kids are going to get hurt in these kinds of activities. And I appreciate his concern. But to a point, I think, holy, you got to let him try it. So clearly, it's not just one way or the other, but that diverse kind of experience that's going to be of the most advantage to kids. The next question is the 40 minutes of exercise. Does it have to be all at once, or can it be done in smaller chunks? The research I read didn't actually address that, but it does look from other research that I've read that it doesn't have to be consecutive, that it can be cumulative throughout the day. So I have a feeling that that would probably translate into no, you don't have to take them out for a 40 minute period and let them run around the schoolyard. You can actually do it in smaller chunks. And there is work by John Rady who has shown that if you bring exercise equipment into a classroom where kids have behavioral problems, ADHD, and things associated with low attentiveness in the classroom, you give them exercise opportunities like treadmill or bicycle, and they do better on exams after a 20 minute bout of exercise than if they haven't had that opportunity. And again, it's probably related to improving their working memory and that sort of thing. Okay, do you want to do the next one? Do you want to take one more? Is there one more there? Oh, the references for strong father attachment. That slide that I put together actually comes from many sources. Much of it is Kyle Pruitt's work on father and how important fathering is as far as baby brain development goes. Another piece of it comes from a series of papers I've just read and I'm blanking on the author's names, but I can make that available and you could post those references.
