Life would be tragic if it weren't funny.

I wouldn't be here today if it were not for the NHS. I have received a large amount of high-quality treatment without which I would not have survived.

The downside of my celebrity is that I cannot go anywhere in the world without being recognized. It is not enough for me to wear dark sunglasses and a wig. The wheelchair gives me away.

If I had to choose a superhero to be, I would pick Superman. He's everything that I'm not.

All my adult life people have been helping me.

…only in the few universes that are like ours would intelligent beings develop and ask the question: “Why is the universe the way we see it?” The answer is then simple: If it had been any different, we would not be here!
