I am reminded of an image that one of my cousins—a woman who lost her husband to a swift and brutal cancer last year—suggested to me recently over email: that living with a terminal disease is like walking on a tightrope over an insanely scary abyss. But that living without disease is also like walking on a tightrope over an insanely scary abyss, only with some fog or cloud cover obscuring the depths a bit more—sometimes the wind blowing it off a little, sometimes a nice dense cover.
