The human brain is a marvel of mysteries, holding answers that we are still uncovering. Dr Theodore Schwartz's book “Gray Matters: A Biography of Brain Surgery” is filled with anecdotes to help us relate to the organ that sits silently in a dark cell inside our skull. Dr Schwartz has performed over 10,000 operations working in an area as small as a one rupee coin. He reflects on the meditative state he gets into during surgery, the role of empathy in connecting with patients and the exhilarating breakthroughs that makes it all worthwhile. Dr Schwartz recounts his punishing schedule when he was a student and the physical endurance coupled with mental fortitude needed to operate for hours on end. It's a life of sacrifice, brilliance and endless curiosity.
