I don't much like being a public figure, because so often how people appear is not how they really are, and I think one of the issues about our society is that we make judgments about people on the basis of very flimsy evidence.

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

People think I appear on television to promote my image. That's not fair. I hate filming. I turned down 'Strictly Come Dancing.' But television is a wonderful opportunity to promote scientific ideas. 'Super Doctors' is a very thoughtful piece.

I do not know of any credible evidence that suggests Dr Zavos can clone a human being. This seems to be yet another one of his claims to get repeated publicity.

I was born with my moustache and, no, I've never been tempted to shave it off. I don't spend a lot of time worrying about my face and, like Gilbert and Sullivan's Katisha, my best feature is my left shoulder-blade.

It is important that legislation keeps pace with scientific progress.

I love the French detective series 'Spiral.' It's quite brutal to watch, but I'm already hooked.
