0:02 Okay. According to a new study from the
0:04 University of Cambridge, uh it's the
0:08 brain stays in its adolescent phase,
0:10 excuse me, up until we're approximately
0:15 32 and after that it rewires into
0:17 adulthood. So Lisa, you are a
0:19 neuroscientist. Talk about what is your
0:20 reaction to this?
0:22 >> Um so this is a new study. It's one
0:25 study. So I always tell folks when you
0:26 come across scientific information,
0:30 what's the source? Is it a chiropractor?
0:30 Um, [laughter]
0:32 no. Is it an influencer? No. But this is
0:35 a legit study and it's one, so it needs
0:37 to be repeated. But, um, yeah, it's, you
0:40 know, we've had this this, um, the data
0:42 has shown historically that we think it
0:44 was like 25 when the brain fully
0:46 developed and now it's extended out to
0:48 32 is what we think it is. And so, what
0:50 does that mean? And it means that the
0:51 most newly evolved part of your brain,
0:53 especially your prefrontal cortex,
0:54 that's the part of your brain that's
0:57 responsible for decision making, problem
1:00 solving, controlling impulses, isn't
1:02 fully at its best, we think, until
1:03 you're about 32.
1:04 >> That explains all the shopping sprees at
1:07 28. I get it.
1:08 >> Shopping spree.
1:10 >> Yes. Impulse control. I had problems.
1:12 Uh, but is there a point where any of
1:14 you felt like, yes, this tracks with my
1:17 life? Like 32. Yeah, that's when I hit it.
1:17 it.
1:18 >> I feel like I came in stages. The first
1:20 one was when I felt like I was
1:21 financially independent from my parents
1:23 which was probably in my early 20s. The
1:25 second was I had an awareness around 25
1:27 as well. I'm going to die one day like
1:29 and I that was like a real wakeup
1:31 moment. And then the third was right
1:32 after giving birth and I remember Jason
1:34 and I were looking at each other and we
1:36 were told you can go and we were just
1:38 like you're going to let us go out of
1:40 this place.
1:41 We had the same feeling.
1:44 >> Yeah. Yeah. I had questioning that. It's
1:46 like what? Nobody's coming with us. It
1:48 was amazing that there wasn't somebody
1:50 who's like, "You need to pass a test
1:52 before you leave this hospital." Like, I
1:54 honestly believe that we have we have
1:56 zero credentials to be doing this. For
1:58 me, it wasn't just having a child that
2:00 made me feel like an adult. I will say
2:02 it was having a child and becoming a
2:05 working mom at the same time. There was
2:07 something that shifted where I went, I'm
2:10 supposed to do all of this. I was like,
2:12 this is adulting and how the heck did my
2:14 mom do this? That was number one. The
2:16 second thing that I did, uh, and this is
2:18 not a humble brag, when I got to a point
2:20 in my career that I thought I could give
2:22 back, I wanted to be able to give back.
2:25 And in 20121, I created a scholarship at
2:28 my university, my alma mater. And I
2:29 never thought I would ever be able to do
2:31 that. And why I wanted to do that was
2:33 because I was able to go to university
2:35 because of someone else's generosity.
2:37 And I always said if I could give back,
2:39 so I have the Melissa Greo Entrance
2:40 Scholarship for Black and Indigenous
2:42 Excellence at York University.
2:43 >> Really? SO CHECK IT OUT.
2:46 >> WELL, I think I think if you are the
2:48 oldest daughter in a family, the answer
2:50 to this question is when you felt like
2:52 as an adult was when your sibling was
2:54 born because in my household it was soon
2:56 as my sister was born, there's a
2:57 nine-year age gap. As soon as she was
3:00 born, I was turned into a co-parent, not
3:02 a sibling. I was expected to help. I was
3:03 doing my own laundry.
3:04 >> Age difference.
3:05 >> Uh nine years. That's what I say. A nine
3:07 year age difference, right? So by the
3:08 time I'm 10, I'm helping with
3:10 everything. warming bottles. I'm
3:12 washing. I'm doing laundry. I'm getting
3:13 the food ready. At one point, I was
3:15 actually taking my my sister to school
3:17 and dropping her off before I went to
3:18 school. And that was in junior high.
3:21 Wow. And there was very little um room
3:23 for error. I felt like growing up there
3:24 wasn't like a lot of wiggle room. I
3:25 don't ever my parents saying to me, "Oh,
3:26 she's just a teenager. Let her make
3:28 mistakes." It was like, "No, no, you
3:29 have to help. You have to help. You have
3:30 to help your sister. You got to help me
3:32 do this." So, I feel like there's a
3:34 group of us who are like, "Oh, 32 must
3:35 be nice."
3:36 >> All right.
3:39 >> For me, it was around 12. Yeah. Right. Yeah.
