How old would Miep Gies be today?

Hermine "Miep" Gies was one of the Dutch citizens who hid Anne Frank, her family and four other Dutch Jews from the Nazis in an annex above Otto Frank's business premises during World War II. She was Austrian by birth, but in 1920, at the age of eleven, she was taken in as a foster child by a Dutch family in Leiden to whom she became very attached. Although she was only supposed to stay for six months, this stay was extended to one year because of frail health, after which Gies chose to remain with them, living the rest of her life in the Netherlands.
