Just how good was the government’s ‘ring of protection’ around care homes during the first wave - and the second? We speak to Steven Johnson about his book ‘Extra Life: A Short History of Living Longer.’

Steven Johnson, author of Extra Life, tells the fascinating history of life expectancy, and the extraordinary achievements of the last century, in which it has practically doubled.It’s a story that has data at its heart, from the ground-breaking invention of the category itself in 17th century London to the pioneering social health surveys of W.E.B. Du Bois in 1890s Philadelphia. Tim Harford spoke to Steven about the numbers beneath possibly the most important number of all.

Popular Netflix documentary Seaspiracy has sparked a lot of debate recently, including some controversy over some of the claims the documentary makes and the numbers behind them.

Wales has given one vaccination dose against Covid 19 to a larger proportion of their population than any other country except a couple of super tiny ones.
