My panji (great-grandma) is 94 years old!!! And she is an amazingly fit 94-year-old too: She has quite some trouble walking and suffers some muscle pain and hearing loss, but thats about it. Her memory is intact (She remembered the last name of my dad's cousin whom he mentioned 8 years ago), she has eagle-sharp eyes (she doesnt and has never and never will wear glasses) and she has a great sense of humour.
