British mathematics professor and broadcaster Hannah Fry has spent many years trying to explain the world through numbers. But when she was diagnosed with cervical cancer she embarked on a new mission – to discover whether the medical world, and we as individuals, make the right choices around treatment. Are patients always given the facts – and the time - they need to make rational decisions? And could we be at risk of unnecessary overtreatment?

Have pyramids really moved 4km south since they were built?
For years, the media has been claiming that the odds of having identical triplets are one in 200 million – we are very suspicious. And we look at apparently concerning reports about women's life expectancy in the poorest parts of England.

And finally we hear about the joys and perplexities of imperial measures with Hannah Fry and Matt Parker. -
Nobel memorial prize winner Daniel Kahneman is one of the world’s most famous psychologists, known particularly for his work identifying the role of cognitive bias in everyday decision making.

We look into this and the claim that the pandemic pushed South African stress levels up by 56%. With guests Abbas Panjwani from Fullfact and Kirsten Cosser from Africa Check.
