So the emotion centers are changing first.

Younger teens are very emotional.

They don't have a lot of self-control or restraint.

And so they know that that's really the sweet spot.

Early teens is a really good time to hook kids.

And even though the minimum age is supposed to be 13, they widely disregard that.

They have all kinds of plans, we know, to try to get into kids' play dates when they're much younger than 13.

So...

This was a very deliberate effort driven by, well, in a sense, the tech companies were in a collective action too, because if Meta doesn't grab all the 10-year-olds, then TikTok will.

So there's a race to the bottom, and the victims are the kids.

So, you know, no, Chuck, I'm not going to blame the kids.

Myelination.

Okay, so an amazing thing about the human brain is that it reaches 90% of full size by the time a kid is six.

Okay, so you got these big brained creatures and then the rest of development is not growing.

Your brain isn't really growing after that.

What's actually happening is you got all these neurons packed in way more than you're gonna have as an adult.

And then you have experienced lots and lots of experience.

You try things and you do it over and over and over again.

And the neurons that you use to do that thing

We say neurons that fire together, wire together.
