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

Science has authority not because of white coats or titles, but because of precision and transparency: you explain your theory, set out your evidence, and reference the studies that support your case.

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.

You are a placebo responder. Your body plays tricks on your mind. You cannot be trusted.
