Duration: 9 min 2 s
Description: This is the last chapter, so I am not teaching you anything new. I am handing you the one thread that runs through all thirty of them: three words that explain why you do what you do when you do it. And five claims I set out to explain that did not survive being checked, including one I had repeated myself.

The receipts behind Chapter 30

The book makes the argument. This supplement shows the evidence, claim by claim: the study, who was in it, the number and where it sits in the paper, what it does not show — and the questions to bring to your own physician. It is written to be shared with your doctor.
