Paul Kalanithi was a rising, young neurosurgeon, but things changed drastically. He was diagnosed with terminal cancer. His tumors had moved from his lungs to his spine, and then up towards his brain. He spent his 20s reading and thinking about mortality, and death. And at 37, Paul spent his last days thinking about what he’d read. His thoughts became his memoir, “When Breath Becomes Air”. He died in March of last year.
