Amanda frowned. "That might not apply in this case, T’sai T’Pau. Harry Potter said mages have much longer lifespans; their magic increases their general healing and durability to a degree they survive what would kill an ordinary human. Their headmaster was more than hundred and thirty years old when he was killed in battle around ten years ago. His basic certification exams were conducted by an older witch who was still alive when they left. Griselda Marchbanks would be around hundred and sixty and was still very active in their equivalence for the Ministry of Education. The more powerful and intelligent mages live longer lives. Harry said it was not unheard of for a sorcerer-class mage to live more than two-hundred years though they tended to die prematurely in duels and wars. Harry has not said so, but I would not be surprised if he is sorcerer-class and the other two are just behind him in power levels."
