But did you know your body undergoes a series of irreversible physical changes when your baby is born?Dr Anna Machin - an evolutionary anthropologist at Oxford University - has spent 10 years working with new dads to gain a unique scientific insight into what it is to be a father in the modern world. Her new book 'The Life Of Dad', the result of that decade of research, shows how it's not just new mums who undergo physiological changes. Dads are also built to be parents.Dr Machin joins Steve and Rich to reveal why their bodies have recently gone through their biggest change since puberty!
