It's a thing with Chinese people to ask how old they are, and the answer is always about 30 years off from your guess. They simply age inwards, whilst keeping a nice and crisp outer shell. But then there are those karate knowing wise old Chinese masters you see on film. Where do they come from? I think it's like caterpillars and butterflies: they just make a cocoon looking all young and emerge as Kong Fu master full of wisdom.
