“I would have to learn to live in a different way, seeing death as an imposing itinerant visitor but knowing that even if I’m dying, until I actually die, I am still living” (Paul Kalanithi, When Breath Becomes Air, emphasis mine). I want to carry this thought with me all the time as I age; it teaches me how to relate to others, all of whom will die someday, and how to relate to myself, who will also die someday.
