The Human Genome is like the Book of Life, revealing the secret of what makes us human. It contains the complete story of human evolution. It holds the key to our future, offering us the intriguing possibility of interfering with fate. Two out of three of us will die for reasons connected with the genes we carry. They affect everything we do, from the amount of alcohol we can drink to how fast we can run. Our life is a lottery and our genes are a legacy we inherit from the past. If we can learn to switch them on and off, we can eradicate disease and even re-design our bodies. In a sense, we're becoming the ultimate controller gene' — the first species to direct the course of its own evolution.
