Faced with a terminal cancer diagnosis, neurosurgeon Paul Kalanithi reflects on his life and passions: neuroscience, literature, and his family.

Life is short, but we go about most days not thinking about our inevitable deaths.

When neurosurgeon Paul Kalanithi found out he was going to die of cancer in his mid-thirties, he wanted to make sure he left a piece of wisdom in writing.

In his memoir When Breath Becomes Air, Kalanithi shares the story of his life and his feelings about his diagnosis.
