Martin O'Brien has lived beyond his life expectancy twice - first at the age of five, and then again at 30. He was born with the life-limiting disease, cystic fibrosis. Now aged 31, he identifies as a Zombie - half-dead and half-alive - which he tries to convey through his physical artwork - he even spent his 30th birthday in a morgue, for art's sake. Sometimes controversial, he talks about how he uses the sexual, and consensual, practice of BDSM to illustrate life with a chronic illness and where the line between raising awareness and exploitation is drawn. Presented by Beth Rose with Emma Tracey. A transcript will be available soon.
