For more than 40 years, Henry Marsh’s job has been to diessect "the most complex structure we know of in the universe, where everything that makes us human is contained". Henry has written a searing, provocative and deeply personal memoir, Admissions: A Life in Brain Surgery, reflecting on life on the surgical front line, including pioneering the awake craniotomy procedure in Albania and Nepal. In this podcast, recorded at the 2017 Sydney Writers' Festival, Sofija Stefanovic interviews Henry about the difficulties of a profession that deals in probabilities rather than certainties.
