Bridget Kendall presents an ideas discussion show which tackles the big questions of our age with some of the world's most eminent minds.
This week, a programme to test how strong your stomach is. Why is slimy slithery food so often unappetizing? And why do babies respond to bitter tastes by screwing up their noses?
We’ll be exploring disgust: when it’s a useful tool to keep us safe from disease and poisoning, and when it’s a gut reaction that could encourage risk-aversion and even predict the way we vote.
