You get a snake that is not a tree climbing snake.

Tree climbing snakes have got their house really close to the head.

You get a ground snake.

And then you put a bit of water around it and then you wrap it in some clay and you leave it out in the sun.

It hibernates and you've got this long skinny thing that looks like a wooden pole.

And you walk in and you say, hey, give me what I want or else I'll make this rod turn into a snake.

And you throw it on the ground, it turns into a snake.

And he says, okay, you can take all your mace and piss off.

Well, we have... OK, so all three of us in this room are past our teens and so our brains take 20% of our blood supply.

But if... So straight away, even for adults, you've definitely got to have the brain higher, you've got to have the heart higher to be able to give enough blood to the brain to keep it going.

But in a person who's 8 to 12...

it's 30 or 40 percent in a four-year-old it's 50 so they've definitely got to have their heart closer to their brain and even when a kid aged four is sitting there doing nothing 50 of all their glucose is running their brain and they're doing weird things like how do i turn the phone off when mummy and daddy's not looking but i mustn't forget how to brush my teeth and go to the toilet

Oh, you're talking about left, right, not up, down.

Is that right?

Have I got it wrong?

Yes.

Oh, okay.

It doesn't matter left, right.

It's just a vertical height that counts.

I totally missed that.
