Dr Karl

And we're not too sure exactly why it helps, but it does for some people, but not everybody, help.

Sorry, got a better answer?

That can help.

So we've just actually been mapping the human brain.

There was a study that came out last year

where they looked at the MRI scans of people of various ages and they found that you start off being relatively inefficient from nought to nine with your brain, but you're making all sorts of connections all over the place and then you gradually shift over to being more efficient but less widespread.

And then as you go through life, you then start at later stages going to something like an airport hub.

So if you want to go from, say, I don't know, Toowoomba to Broken Hill, you have to go...

into either Brisbane or Sydney.

And so you've got to use the hubs.

And in your early days, you can make connections all over the place.

But in the later days, you tend to have to go through hubs.

So we're gradually learning about the brain.

Watch this space.

I'm sorry, Xander.

You've asked one of the big ones to start off the show with, Dr. Xander.

How can you do that to us, but we still love you anyway?

Yeah.

Thank you for that.
