This week we talk to the Sandro Galea, Dean of the school of public health at Boston University.

His book, called Well: What We Need to Talk About When We Talk About Health (£18.99, OUP) takes a deep look at the differences between health and medicine, and looks at how everything from the environment, taxation, education and even luck plays a part in the overall health of a nation.

Speaking before the coronavirus pandemic, he explains the surprising factors that influence public health, which countries are doing it well, and why he felt he had to write this book.
