I like travelling on my own. It means I'm completely free to think about what's around me.

Childhood depression tends to be more common in inner cities, being most frequently related to serious social deprivation, bullying, domestic violence, wartime experience and famine. It is, for example, a serious problem among children who are traumatised refugees.

I think that good parenting should allow children to be children. That naivety and slightly open way of looking at the world is very valuable.

Medicine, which I wouldn't be without, has also been a force for... less good. For example, if you look at our mishandling of the immune system, using antibiotics in children and avoiding infection, we've certainly increased the risk of asthma.

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

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.
