The diagnosis was immediate: Masses matting the lungs and deforming the spine. Cancer. In my neurosurgical training, I had reviewed hundreds of scans for fellow doctors to see if surgery offered any hope. I'd scribble in the chart 'Widely metastatic disease - no role for surgery,' and move on. But this scan was different: It was my own.

It's fun and super exciting to see how other people work, how other people write music, and how other people put things together. To me, it's an endless learning process, and I love doing it because everybody works so completely differently.
