There are more than seven billion people on the planet.
They have, on average, over 100 billion nerve cells in their brains and 5 litres of blood pumping through their bodies. Their skeletons are made up of 206 bones and their hearts beat approximately 72 times per minute. They are connected to each other in more ways than they can possibly imagine.
Philip is one of them. Sue is another. This is their story.
It is the story of one year and two lives and what it means to live in them.
It is a story about love and courage, risk and betrayal. It is a story that will make you look at the world with new eyes.
