4:07 The Sunday Feature: Talking Heads - Inside Out: The Chemistry of Food, Sex and Ageing

In three Sunday Feature programmes, Kim Hill talks to chemists to examine some of life’s complex questions. What exactly are free radicals? How does UV light affect our skin? Is there a chemical difference between males and females? And is the saying “you are what you eat” correct?

The 2011 Talking Heads series was recorded at public events in Auckland, Wellington and Christchurch, and produced by the Royal Society of New Zealand in association with Radio New Zealand and the MacDiarmid Institute.
