CAMERON Diaz wrote 'The Body Book' because she is a "science nerd" and fascinated by how things work.
The 41-year-old actress has recently been working on 'The Body Book' and says she was inspired to write the tome because of her fascination with how things work.
She said: "I'm a science nerd. I like to know why things work the way they do. I thought that the body was probably the most important thing to understand how it works since we all have one, and we don't really know that much about it."
The 'Bad Teacher' star also urged women to take better care of their private parts and treat their genitals like "beautiful flowers".
Speaking on 'Chelsea Lately', she said: "We think the vagina is on the outside. I say grab a mirror and play along. Get in there.
"Learn about it. You're supposed to treat it like the beautiful flower that is, the delicate flower that it is. And you're supposed to nurture it in all the ways that it needs nurturing. Watering it. Fertilising it. It needs nourishment. It's hungry."
And Cameron also called women not to permanently remove their pubic hair.
Explaining why she included an excerpt about pubic hair preservation, she said: "Because it's a science book, and since we used to be covered in hair, and now we're not except for a few places, I figure there's a purpose for that hair.
"So I put some of the purposes for it and I also suggest that no mater how you enjoy grooming it throughout your life - whether it's shave it all off, wax it all off, putt a bulls eye, birthday cake, I don't care - just, girls, think about not taking it all off forever. Permanency means forever. It doesn't come back. You might change your mind in a few years."
