Oral processing.

OK.

This is something, I went to this university in the Netherlands where there's not a whole lot of people who go into the field of oral processing.

You have to go to an institute in the Netherlands.

So what it's all about in there is bolus formation.

Bolus.

Bolus formation.

First of all, you're taking your food apart.

You're grinding it up, taking it apart.

The tongue.

The wonderful tongue.

The cheeks.
