Actually, I hate to say it, but she'd probably do okay at about 90. 4'11" at her age, she's probably lost all of her muscle mass so I can see her weighing under 100... she probably looks like a bird, though. Oh well, they say the key to living long is having goals.
I wonder who has more fun... the skinny, bird ladies or the big, huge ones who wear massive Jackie O sunglasses (from 1975), red and gold sequin-appliqued caftans, and whoop it up twice a year with the girls in Boca!!!
