Michelle Au started medical school armed only with a surfeit of idealism, a handful of old 'ER' episodes to reference, and some vague notion about 'helping people'.This is the story of how she grew up and became a real doctor. Through her years in medical training, she also attempts to maintain a life outside the hospital as she and her resident husband decide to have a baby.A new mother struggling to balance long days and nights in the hospital with her 'real' life, Au finds herself in the classic struggle of working motherhood, trying to do two equally high-stress jobs without losing her sanity or sense of humour. THIS WON'T HURT A BIT is a story about the imperfect, occasionally ridiculous, never boring process of medical training and life outside it, where an ordinary person can learn the kind of doctor and mother she wants to be under the most extraordinary circumstances.
