"What can science tell us about the way we are? Three celebrities discover the truth about a characteristic that they feel defines them. In each program, a famous face goes on a journey of discovery to answer the question: why am I the way I am? Their mission: to discover what the latest scientific research can tell them about the defining trait, talent or characteristic that really matters to them. Celebrities include John Barrowman investigating the origins of his homosexuality; Colin Jackson and his athletic ability; and Vanessa-Mae discovering the roots of her musical skills. These are personal, individual and scientific insights into each celebrity's characteristics. Each celebrity takes part in a series of dynamic tests to find out whether their trait is caused by genetic programming, upbringing, lifestyle or environment."--container.
