Wow, Barbara! Praying your sister and grands are doing better.
Yvonne, you sound like my mamaw. She still walked everywhere until six months before she died. My teen kids were surprised at how old she was because she didn't act it. When my mom died one of her older sisters stayed awhile. My husband asked didn't she have a job. I pointed out she was 72.
I am hoping for those genetics because Mom died at 63. I think staying active is key.
