News has a way of distancing us from events, even as it informs us about them. News articles almost always present both the event and the responses at the same time - how is President Barack Obama or Congress responding to the events? I think this reflects a deep need we have to feel that things are under control and that events are subject to our influence.

There was a period of a few months, however, when I had a dreadful physical pain. I had just started writing a particular section of the novel and was initially worried that it would affect my work. I was woken by awful nightmares; I saw several doctors, tests were performed, nothing came of them, and the medics were mystified.It was two days after I finished writing the section that the penny dropped. The pain had suddenly disappeared and so too had the nightmares. I'd got things muddled. The pain and the nightmares were both psychosomatic.

A poison can hardly be called safe if for some reason specific to me it's ineffective against, say, my body. But the power of story on the human mind is such that anecdote is often more persuasive than numbers. That's why news stories often concretize the impact of a change in government policy by following the story of one person.

I had a tough childhood, yes. I was born in rural Bangladesh to parents who had had no education beyond high school. We moved to the UK where I grew up in poverty, in some of the worst conditions in a developed economy, before moving to the projects - heaven - and I went to unremarkable schools before going to university. My father was a bus conductor first and then a waiter, and my mother a seamstress.

The technology broadens an individual's social field massively and at the same time makes it much, much easier and cheaper to consume gossip. We have the same appetite for gossip, but now its acquisition is even easier than grabbing sugary and fatty foods off a supermarket shelf. And look where that got us. When you watch people in public desperately punching away at their machines, it's hard not to think of addictions.

I am sympathetic to the kind of faith that does not evangelize or raise banners but is the faith drawn on by a lone human being as a means of support or as an organizing principle or even as mere practice. It is faith that is born of humility and an understanding of one's own frailty. I can recognize it because I have met many people who exhibit this kind of faith.

Until I reached my late teens, there was not enough money for luxuries - a holiday, a car, or a computer. I learned how to program a computer, in fact, by reading a book. I used to write down programs in a notebook and a few years later when we were able to buy a computer, I typed in my programs to see if they worked. They did. I was lucky.
