Not the nails, said he, the corns.

And if this continues the toe cell would die.

Finger, finger, finger, finger, finger, finger, finger, finger.

Finger, finger, finger, finger, finger, finger, finger, finger. OK.

So white ball and finger, finger, finger, finger, finger, finger, finger, finger.

Finger, finger, finger, finger, finger, finger, finger, finger. Green.

Pink, finger, finger, finger, finger, finger, finger, finger.

And this toe cell is just trying to make a living.

And it might kind of end up getting all the way around our toe cell.

Now, one more time, and finger, finger, finger, finger, finger, finger, finger, finger. Open.

So white ball and finger, finger, finger, finger, finger, finger, finger, finger. Pink.

Now, one more time, and finger, finger, finger, finger, finger, finger, finger, finger.

Finger, finger, finger, pink or finger.

Finger, finger, finger, finger. Yellow.

So our toe cell is getting swamped, literally getting kind of covered by its own waste.

So, what a toe cell needs, and what every cell needs, and that could be a finger cell or a skin cell, or really any cell that's living, needs flow.

Finger

Toe

long, I would say within minutes, our toe cell is thinking, Well this is not a very happy way to live! this is actually really very sad, this is awful.

Belt.

And I got a twitchy finger, so get.

I don't have the strength to lift a finger.

Seat belt.

Seat belt!

The seatbelt?

I have a pain in my little toe.

Put on your seat belt.

Drop your cartridge belt.

Drop your gun belt.

Take off your gun belt.

No girdle?

Let's say a little toe cell.

If you stub your toe, that's a one A argh.

So always wear your seat belt.

The heart of the bicarbonate belt.

It's the belt of my cap. It's loose.

A fibre belt.

Each finger can be snapped from the bar separately.

You understand now?

So the yellow bar represents car seats, the orange bar lap and shoulder, and the red bar lap only seatbelts.

I mean remember, the heart is made up of thousands and thousands, actually tens of thousands of cells and those cells, just like our toe cell that we drew, they also need oxygen, nutrients, and have waste.

And this goes all the way to the Kuiper belt all of these over here, so all the way out to the Kuiper belt.

Fasten your seat belt, please.

It's like a geological conveyer belt

ROBOT Fasten your seat belts, gentlemen.
