My parents, both doctors, were fit and healthy. They were immigrants from India, raising me and my sister in the small college town of Athens, Ohio, so my grandparents were far away. The one elderly person I regularly encountered was a woman down the street who gave me piano lessons when I was in middle school. Later she got sick and had to move away, but it didn’t occur to me to wonder where she went and what happened to her. The experience of a modern old age was entirely outside my perception. In college, however, I began dating a girl in my dorm named Kathleen, and in 1985, on a Christmas visit to her home in Alexandria, Virginia, I met her grandmother Alice Hobson, who was seventy-seven at the time. She struck me as spirited and independent minded. She never tried to disguise her age. Her undyed white hair was brushed straight and parted on one side, Bette Davis–style. Her hands were speckled with age spots, and her skin was crinkled. She wore simple, neatly pressed blouses and dresses, a bit of lipstick, and heels long past when others would have considered it advisable.
