Every time I see my mom, she tells me, “Dye your hair. You look like an aging hippie.” / I’m 51, and while I fear I’m aging out of a lot of things—the ability to run miles and miles without getting injured, for one—I’m not aging out of looks. There’s a photograph of the writer Susan Sontag taken at 58. She’s lying back, holding her elbow up with her hand resting on her head. Sontag was known for her political theories, but also for the thick swath of gray hair right in front, while the rest was dark brown. In the photo, you can see the gray and also the loosening of the skin under her eyes. She looks strong and calm. The picture was taken by Annie Leibovitz, who was her lover.
