(Not a bad group to have be your first: the Beatles, 1964.)
My grandmother lived many years on her own after my grandfather died. Then when she was 90, she developed cataracts. After she fell one time, she stopped her daily walks to the store and to visit friends. Even though she had the eye surgery, she retained her fear of falling. Then living a more sedentary life, she only lived until 93.
My father had a stroke when he was 80. They said he might never walk or speak again. Hah! He survived the Battle of the Bulge; he wasn't going to let a stroke keep him down. Up until maybe the week before he died, at 90, once my mother helped him out of bed, she went back to sleep; and, if it took him a v-e-r-y long time, moving around one inch at a time with the walker, and with only the use of one hand, his left, he still set the table and made her a pot of coffee - just as he'd done every day their whole lives together.
When we try to pick out anything by itself, we find it hitched to everything else in the Universe.
