There is one thing that everyone on earth has in common. We all live, eat and breathe within the human body. For two years I’ve been exploring this unique dwelling 1 place. I want to show you what I've seen.

To come with me, you'll have to cross the globe from Australia through Africa to America. You'll have to journey into space and into a place as mysterious but much closer to home. We've developed new techniques to help you get there, new cameras to show you the way. (ah) And we'll look at familiar things with a fresh eye. You'll journey with me on the road that your body takes, through dangers, through miracles and through time. We will see the human body in all its forms, from our beginning to all our ends.

I am a doctor and a scientist. I've spent my working life looking at the human body. Now I am going to see it in a new light. Come with me.

This is Charlotte. She was born just a few hours ago. Like most of us at birth, there's really nothing to her. A bit of fat, a little sugar, a bit of protein, actually She is 75 percent water! She is really just a collection of chemicals. And yet she is the most complicated thing on earth. And during her lifetime, she'll achieve the most amazing things.

She will eat for nearly three and a half years, consuming 7,300 eggs, and 160 kilograms of chocolate .she will produce 40,000 liters of urine and spend over 6 months on the loo. She will dribble 2 145 liters of saliva 3 before her first birthday.
