But it's all around us, Katrina.

When you say one down, six million to go, that sense of being surrounded by this, I mean...

I think what kills me is to see women who are in a labour ward and then they show themselves sort of a few months later with a bouncing, beautiful baby.

And they are back to size zero.

I don't know how realistic that is or but it seems poisonous to me.

And what comes across very clearly in the book, Catriona, is that it's also a class thing, that the classes react differently.

I think you say that for your working class friends, injectables and fillers are absolutely normal.

The people you meet in universities

They all end up in the same place, but they just do it differently with their yoga and running and tiny salads.

It's okay.

I say radiating energy.

What's next, Catriona?

Have you got a book on the way?

I cannot tell you how delighted I am about that, because as I say, that was the light that kept shining for me throughout those books.

It's beautiful.

It could be bleak.

And can you just distill that book into one thought before you leave?

Is there one piece of self-help you'd leave the listeners with?

Does this doll look like you?

There's something very touching about that image.
