Respected sports journalist and writer Clinton van der Berg talks about his journey writing his book 'Guns And Needles: A Journey into the heart of South Africa's sport's steroid and drug culture." Van der Berg shares how he managed to get sports people, accused and convicted of doping, to tell their story; how he found out about the shocking incidences of doping in school and junior sport and why both young and old are susceptible to the performance benefits of illegal supplements and drugs. It's a cautionary tale for amateurs and professionals alike no matter what country you come from.Note: We are aware the sound on this one from Clinton is really poor. We had major connectivity problems over the recording and try as we might to correct it post-recording, we just couldn't. We are really sorry, it's hugely frustrating and does detract from the listen and the content. We can only apologize for it and commit to making sure it doesn't happen again in future.
