If I tell you that my grandmother is a strong woman, what will you picture in your mind? Will you think of a fit granny wearing breathable spandex and flexing her biceps? Or will you conjure up someone who has held her own through a hard life? Maybe you will imagine a woman whose heart is 98.5 years old but still beats when it should. Don’t forget the deep wrinkles such a woman must have, and a cheek with skin so thin you want to place it under glass in a museum, or at least lay your own relatively taut cheek lightly against it for a moment. What will the feel of this cheek, almost a century old, tell you about your own mortality?
