“Yes. I’m a doctor, an epidemiologist, and lots of my professional colleagues flip back and forth between industry and medical roles. I know them; they are not bad people. But it is possible for good people in bad systems to do things that inflict enormous harm.”

Children can be disgusting, and often they can develop extraordinary talents, but I’m yet to meet any child who can stimulate his carotid arteries inside his ribcage.

Amazing things happen when you pull individual pieces of information together into larger linked datasets: meaning emerges, as you produce facts from figures.

I hope that you will be asked to participate in a trial at some stage in your disease

The placebo effect is one of the most fascinating things in the whole of medicine. It’s not just about taking a pill, and your performance and your pain getting better. It’s about our beliefs and expectations. It’s about the cultural meaning of a treatment.

I spend a lot of time talking to people who disagree with me – I would go so far as to say that it’s my favourite leisure activity.

Data is the fabric of the modern world: just like we walk down pavements, so we trace routes through data, and build knowledge and products out of it.

These corporations run our culture, and they riddle it with bullshit.

If I was writing a lifestyle book it would have the same advice on every page, and you’d know it all already.

I’ve detected myself using a new rule of thumb: if you don’t link to primary sources, I just don’t trust you.

The plural of anecdotes is not data

Eat lots of fruit and vegetables, and live your whole life in every way as well as you can: exercise regularly as part of your daily routine, avoid obesity, don’t drink too much, don’t smoke, and don’t get distracted from the real, basic, simple causes of ill health.

But as we will see, even these things are hard to do on your own, and in reality require wholesale social and political changes.

There is this peculiar blind spot in the culture of academic medicine around whether withholding trial results is research misconduct. People who work in any industry can reinforce each others’ ideas about what is okay.

I agree, the world would be a better place if doctors were less enthusiastic about adopting very new drugs.

One of the things I always found interesting is the same tricks are used to distort medicine in all of those domains.

I think you’ll find it’s a bit more complicated than that.

In the next few years I’d love to play a female version of Doctor Who. I know exactly how I would play her – she would be crafty in a clever kind of way.

I truly feel the best doctors are ones who are criticized by nurses, patients and family. They do not make excuses and learn from their mistakes.

A doctor once told me that with crying you aren’t sure what its derivation is. If someone comes at you with a knife, you don’t cry: you scream, you try to run. When it’s over and you’re OK, that’s when you cry.

I actually wanted to be a doctor. But doing all those horrid rat dissections made me faint. I studied science till the 12th standard and later took up commerce. I was planning to do chartered accountancy, but fate had something else in store for me.

There’s huge satisfaction in that, but I’ve got to credit all the doctors and trainers in Cleveland.

I told my wife I’m afraid to go back to the doctor because I’m afraid they’re going to look at you and say: ‘ma’am, just sell him for parts. It’s like that old car that as soon as you fix one thing, something else goes out on it.

You can’t be a doctor if you don’t know the entire parts of the body.

We would all be better off if our doctors took us aside, sat down next to us, and gave us this compassionate, yet universally true, warning,
