l Swamp Lions, Nat Geo Wild, 20.00
The Swamp Pride is on its knees. Its mighty male was killed by poachers, leaving three moms and their cubs defenceless. Busanga Swamp is a quagmire. Hunting in shoulder-deep water is all but impossible, and deadly hippos and crocodiles patrol the waters. Keeping cubs alive is hard work, but for these lionesses it just got harder: two large young male lions are hunting them down. The males want to claim the Swamp Pride as theirs, but to take over a pride they must kill its cubs. The mothers must fight to make sure that doesn’t happen.

Michael Mosley goes to physical and mental extremes to unravel the biological, sensory and evolutionary mysteries of pleasure and pain. He learns how pleasure is at the root of our ability to make sense of the world, and how it reinforces healthy behaviours such as eating, having sex and keeping warm. He eats a year’s worth of chocolate to find the precise moment when pleasure turns to pain. Pain is a part of everyday life, but it is a mysterious, subjective phenomenon, dependent on our ability to articulate it.
