However pragmatic you are, it is very demanding being a new parent.

I don't like seeing myself on television and I don't enjoy filming. What I actually enjoy is thinking about how I am going to express something or how we are going to make the visual metaphor.

Nearly all inventions are not recognised for their positive side either when they're made. So, for example, scientists didn't go out to design a CD machine: they designed a laser. But we got all sorts of things from a laser which we never remotely imagined, and we're still finding things for a laser to do.

Parents should talk to their children, even when they are babies and can't talk back.

My own field, the prevention of genetic disorders in babies, has been possible only because of humane work on animals.

You can now modify the genes of large animals, and the largest animal we are concerned with is the human.

We live longer and healthier lives than ever before. Animal research has improved the treatment of infections, helped with immunisation, improved cancer treatment and had a big impact on managing heart disease, brain disorders, arthritis and transplantation.
