I got into music, I was in a band, I was at art school. I was quite trendy, although I'd hate to meet myself. The over-preening, the pretentiousness, the arrogance of youth! I think, 'Oh, that guy was so full of himself.'

My parents didn't take me to the theatre to see Chekhov when I was growing up - we went to see 'Francie and Josie' once every five years.

I don't remember 'Doctor Who' not being part of my life, and it became a part of growing up, along with The Beatles, National Health spectacles, and fog. And it runs deep. It's in my DNA.

My childhood growing up in that part of Glasgow always sounds like some kind of sub-Catherine Cookson novel of earthy working-class immigrant life, which to some extent it was, but it wasn't really as colourful that.

I have charity work that I do. I started my own charity, the Friends of the Prostate, and I'm also working on awareness of the deviated septum. I do this because not many people are interested in it. There's also Save the Funnel-web - they're dying out.

I have experienced a murderer among my friends. Many, many years ago. At close range I have seen the impact of it. I knew the victim, I went to the funeral, I have been to the house, to the specific room where the killing took place, and I was stunned by it. It's such a blow.

Since Bin Laden's death, many Americans have decided that our job in Afghanistan is done. They see a victory in the counterterrorism campaign, and are tired of the corruption, confusion and dysfunction of the nation-building campaign.

I think I've become more aware of aging in the last couple of years because of friends dying of cancer or friends' parents dying and myself - I'm still healthy, but I'm aging, and that's something that I think about more, even though I shouldn't be too concerned.
