Tim Harford investigates some of the numbers in the news. This week:

Is it true that someone needs to earn £71,000 before they receive more money than a family on benefits?

Did Canadian prime minister Mark Carney get the GDP of Canada and the Nordic countries wrong?

Are 1990s pop icons Right Said Fred right about what they said about church attacks?

Is a sauna really ten times as hot as Wales in the winter?

And Tim hits the science lab treadmill to find out if he can run a four-hour marathon.
