So, when many years later I really was near death as a result of a haemorrhage after a miscarriage, and heard a doctor saying “She’s very near collapse – call the lab and tell him to run” and understood that the “him” was the person fetching the blood they were going to pump into me, I was not in the least alarmed as I dimly wondered if I had the strength left to think some suitable Last Thought, concluded that I hadn’t, and said to myself the words: “Oh well, if I die I die.” I was sure, then, that nothingness was just that.

Today is a pretty important day. It was August 15th, 2007, when I was told I likely had "three to six months of good health left." Today is six months from that day. Just to prove I'm still alive, here I am, holding today's New York Times! I rode my bike today; the cumulative effects of the chemotherapy are hurting my stamina some, but I bet I can still run a quarter mile faster than most Americans. The doctors weren't wrong; they always said that if the palliative chemo worked, I'd buy more time, but that it was a long shot. And the doctors have done a brilliant job of tweaking my regimen to help my odds. How much longer this will work is hard to know, but I'm going to keep having fun every day I have left, no matter how many or how few of them I get.

It is a very rare affliction. A GP would expect to meet it once in a career and this form of brain cancer is unpredictable and dangerous. Usually, this tumour might give you only a two-year span since its discovery. I have had two operations and one course of radiotherapy and now three chemotherapies (one currently starting). My death is, in a sense, imminent. I say to myself: I am dying. Something in my head is hurrying to kill me.

I only ever wanted to be an actor or a rock star. I was suspended from school in the sixth form and allowed back only when I promised to join the army. But I lied.

Not doing Top Of The Pops when The Young Ones’ single went to number one.

I practise stoicism. Not the stiff-upper-lip, modern stuff, but the ancient Greek philosophy. You have to accept what you can’t change. I try to face forwards all the time. When that doesn’t work, I think about buying a machine gun.

My granddaughter is only one, but she gives the best hugs. That’s when I’m happiest at the moment.

I worked in the largest pork pie factory in Europe. I had a plastic mushroom-shaped thing and had to tamp down the meat into the pie base. It was a conveyor belt of pies from nine to five. The worst thing was the crackly AM radio, which was played loudly through the tinny tannoy system. I still can’t listen to I’m Not In Love by 10cc without thinking of raw minced pork.

Jazz, Delicious Hot, Disgusting Cold by the Bonzo Dog Doo-Dah Band. Whenever Rik and I got stuck writing a script, we would put this on and the world would immediately seem to be a more stupidly brilliant place again.
