And so I think it's really important for, again, our parents and our adolescents, our listeners in general, to understand that if you're not eating enough... and also being at this age of adolescence, your brain is not flexible, right? For you to be able to not think in these concrete, you're only thinking in this concrete way, or just, can you go into it a little bit more?

Absolutely.

I want to just, You asked a lot of things in that one question, but I want to highlight what you said, which is about the undernourished brain just not being able to function at capacity.

I mean, so every adolescent, correct, the brain is not fully formed.

We say until 25, but I mean, really, that's just when the frontal prefrontal cortex sort of solidifies and is able to move toward higher level thinking in the more abstract sense.

But you know, experience counts for everything.

The older you get, the more you learn, the more connections, literally you are making neuronal connections in your brain that are growing your brain and increasing your ability to think and reason.

Just for nutrition data and collecting and understanding, what does it mean for a ferritin on this level? What does it mean of the T3? Why do I have to look at the B12? So share with us that.
