A grandmotherly woman, white-haired, wrinkled, but beautiful and vibrant, with a twinkle in her eye. (my grannie
) I am thinking a beauty shot type of image almost. Close up, nowhere to hide, where you see everything.
This will sound completely inappropriate, but I love old people. I love that you can look at them and know that if they have lived this long, they have seen and been through some things. I love old people who still have a spring in their step and a zest for living. That, to me, is strength and survival.
Good luck.
