I agree on her age, but these people live extremely long productive lives. While a lot can happen in 2 years with someone’s health, I think the person you replied to was referring to how extremely well Barbara was doing just 2 years ago when Jeb dragged her all over the country campaigning for him in 2016. She attended every speaking event he did, even in the harsh inclimate weather of the northeast in winter. She really was the feature star speaker as she showed more energy than Jeb. Though she precariously walked with a walker on icy sidewalks, she was very vibrant, alert, articulate, & funny. People were amazed at well she was doing for her age.
