How could you be this far along in life and still so unsettled? How could you know so much and still be this baffled by it all? Was this what enlightenment felt like, an understanding that life is a cancer that metastasizes so slowly you only have a vague and intermittent sense of your dying? That the dying is happening slowly enough that you get used to it? Or maybe that wasn’t life. Maybe that was just middle age.
