Both in Britain and America, huge publicity has been given to stem cells, particularly embryonic stem cells, and the potential they offer. Of course, the study of stem cells is one of the most exciting areas in biology, but I think it is unlikely that embryonic stem cells are likely to be useful in healthcare for a long time.

I don't believe in regretting - one should try to move on. My mum was good at that. She was deeply in love with my father, and he died when I was nine. She remarried, and her second husband died, too. I saw the grieving process she went through. My mother had this way of moving on. It was a fine trait.

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

My father died when I was nine, but I came from a stable family environment, which I think does contribute to being well-behaved.

When I grew up, we didn't have a TV, and I think more families today have ambitions of getting out of their environment, such as sending their children to university.

We must not fail to recognise that television can be a hugely positive influence in children's lives, one of the greatest educators in contemporary society and an increasing influence on all the children followed in 'Child of Our Time.'

It is important that legislation keeps pace with scientific progress.
